The linear acceleration of collar D when θ = 60° is - 693.867 inches per square second.

How to determine the angular velocity of a collar

In this question we have a system formed by three elements, the element AB experiments a pure rotation at constant velocity, the element BD has a general plane motion, which is a combination of rotation and traslation, and the ruff experiments a pure translation.

To determine the linear acceleration of the collar ([tex]a_{D}[/tex]), in inches per square second, we need to determine first all linear and angular velocities ([tex]v_{D}[/tex], [tex]\omega_{BD}[/tex]), in inches per second and radians per second, respectively, and later all linear and angular accelerations ([tex]a_{D}[/tex], [tex]\alpha_{BD}[/tex]), the latter in radians per square second.

By definitions of relative velocity and relative acceleration we build the following two systems of linear equations:

Velocities

[tex]v_{D} + \omega_{BD}\cdot r_{BD}\cdot \sin \gamma = -\omega_{AB}\cdot r_{AB}\cdot \sin \theta[/tex]   (1)

[tex]\omega_{BD}\cdot r_{BD}\cdot \cos \gamma = -\omega_{AB}\cdot r_{AB}\cdot \cos \theta[/tex]   (2)

Accelerations

[tex]a_{D}+\alpha_{BD}\cdot \sin \gamma = -\omega_{AB}^{2}\cdot r_{AB}\cdot \cos \theta -\alpha_{AB}\cdot r_{AB}\cdot \sin \theta - \omega_{BD}^{2}\cdot r_{BD}\cdot \cos \gamma[/tex]   (3)

[tex]-\alpha_{BD}\cdot r_{BD}\cdot \cos \gamma = - \omega_{AB}^{2}\cdot r_{AB}\cdot \sin \theta + \alpha_{AB}\cdot r_{AB}\cdot \cos \theta - \omega_{BD}^{2}\cdot r_{BD}\cdot \sin \gamma[/tex]   (4)

If we know that [tex]\theta = 60^{\circ}[/tex], [tex]\gamma = 19.889^{\circ}[/tex], [tex]r_{BD} = 10\,in[/tex], [tex]\omega_{AB} = 16\,\frac{rad}{s}[/tex], [tex]r_{AB} = 3\,in[/tex] and [tex]\alpha_{AB} = 0\,\frac{rad}{s^{2}}[/tex], then the solution of the systems of linear equations are, respectively:

Velocities

[tex]v_{D}+3.402\cdot \omega_{BD} = -41.569[/tex]   (1)

[tex]9.404\cdot \omega_{BD} = -24[/tex]   (2)

[tex]v_{D} = -32.887\,\frac{in}{s}[/tex], [tex]\omega_{BD} = -2.552\,\frac{rad}{s}[/tex]

Accelerations

[tex]a_{D}+3.402\cdot \alpha_{BD} = -445.242[/tex]   (3)

[tex]-9.404\cdot \alpha_{BD} = -687.264[/tex]   (4)

[tex]a_{D} = -693.867\,\frac{in}{s^{2}}[/tex], [tex]\alpha_{BD} = 73.082\,\frac{rad}{s^{2}}[/tex]

If a 5-kg object experiences a 10-N force for a duration of 0. 10-second then what is the impulse exerted by the force on the object? What is the momentum change of the object? What is the change in velocity for the object?

Answers

Answer:

orce = rate of change of momentum which is m a if the mass is constant

10 Newtons = change of momentum/0.10 second

so change of momentum = 1 kg m/s

by the way the change in speed would be 1/5 = .2 m/s

Explanation:

If a 5-kg object experiences a 10-N force for a duration of 0. 10-second then the impulse exerted by the force on the object would be 1 Ns, and the change in the momentum would be  1 Ns.

What is momentum?

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

As given in the problem If a 5-kg object experiences a 10-N force for a duration of 0. 10-second then we have to find out what the impulse exerted by the force on the object.

P = force × time

  = 10 × 0.1

  = 1  Ns

Thus, If a 5-kg object experiences a 10-N force for a duration of 0. 10-second then the impulse exerted by the force on the object would be 1 Ns, and the change in the momentum would be  1 Ns.

collides with object Y
.

Consider the situation in which the objects collide but do not stick together. Which of the following predictions is true about the center of mass of the two-object system immediately after the collision?

Answers

After the collision, object X will move at a speed of 2 m/s in its original direction while object Y will move at a speed of 5 m/s in its original direction.

Elastic collision of the two objects

When the two objects collide but do not stick together, the type of collision is elastic collision.

In elastic collision, both momentum and kinetic energy are conserved.

Final velocity of the two objects after collsion

mu₁ + mu₂ = mv₁ + mv₂

5m + 2m = mv₁ + mv₂

m(5 + 2) = m(v₁ + v₂)

7 = v₁ + v₂ -------- (1)

Apply the concept of one direction velocity;

u₁ + v₁ = u₂ + v₂

5 + v₁ = 2 + v₂

v₂ = v₁ + 3 ------ (2)

Solve (1) and (2) together;

7 = v₁ + v₁ + 3

4 = 2v₁

v₁  = 2 m/s

v₂  = 2 + 3 = 5 m/s

Thus, after the collision, object X will move at a speed of 2 m/s in its original direction while object Y will move at a speed of 5 m/s in its original direction.

Explanation:

It's because the difference in speed of light and sound

Light has speed about 3×10^8m/sSound has speed 344m/s

So we hear thunder later

Answer:

C

Explanation:

Lightning is a giant spark. A single stroke of lightning can heat the air around it to 30,000 degrees Celsius This extreme heating causes the air to expand at an explosive rate. The expansion creates a shock wave that turns to a booming sound wave, better known as thunder. Thunder & lightning occur at roughly the same time, although u see the flash of lightning before u hear the thunder. This is because light travels much faster than sound.Lightning always follows the easiest path. Lightning strikes buildings or projecting objects such as trees, poles, wires or building than larger, flatter surfaces because the material in them provide easier paths to the ground than the other. The primary target of lightning are lone buildings.

Therefore, Thunder Follows The Easiest Part. And it is not (A) because Thunder Follows A Lightening Not Vice Versa.

what is the result of ocean acidification

Answers

Answer:

Ocean acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve.

Answer:

The intake of carbon dioxide (CO2) from the atmosphere causes ocean acidification, which is the continual decline in the pH value of the Earth's oceans. The burning of fossil fuels by humans is the primary cause of ocean acidification. The amount of carbon dioxide absorbed by the ocean grows in lockstep with the amount of carbon dioxide in the atmosphere. This causes a sequence of chemical reactions in the seawater, which has a negative impact on the, however, their rine life that lives beneath the surface. Carbonic acid is formed when carbon dioxide dissolves in seawater (H2CO3). The pH value of the ocean surface is estimated to have decreased from approximately 8.25 to 8.14 between 1751 and 1996, representing a nearly 30% increase in H+ ion concentration in the world's oceans (note that the pH scale is logarithmic, so a change of one pH unit equals a tenfold change in H+ ion concentration). The pH of the ocean in 2020 will be 8.1, according to the National Oceanic and Atmospheric Administration.

This question involves the concept of the law of conservation of momentum.

The horizontal speed acquired by catching the ball will be "0.223 mph".

Law of Conservation of Momentum

According to the law of conservation of momentum applied in horizontal direction:

The magnetic flux through a coil of wire containing two loops changes at a constant rate from -58 wb to 38 wb in 0. 34 s. What is the emf induced in the coil?

Answers

Since the magnetic flux through a coil of wire containing two loops changes at a constant rate from -58 wb to 38 wb in 0. 34 s, the emf induced in the coil is -5.65 V

Induced emf in coil

The induced emf in the coil is given by ε = -NΔΦ/Δt where

ΔΦ = change in magnetic flux Φ₂ - Φ₁ where Φ₁ = initial magnetic flux = -58 Wb and Φ₂ = final magnetic flux = 38 Wb and and Δt = change in time = t₂ - t₁ where t₁ = initial time = 0 s and t₂ = final time = 34 sand N = number of loops of coil = 2

Since ε = -NΔΦ/Δt

ε = -N(Φ₂ - Φ₁)/(t₂ - t₁)

Substituting the values of the variables into the equation, we have

ε = -N(Φ₂ - Φ₁)/(t₂ - t₁)

ε = -2(38 Wb - (-58 Wb))/(34 s - 0 s)

ε = -2(38 Wb + 58 Wb)/(34 s - 0 s)

ε = -2(96 Wb)/34 s

ε = -192 Wb/34 s

ε = -5.65 Wb/s

ε = -5.65 V

So, the emf induced in the coil is -5.65 V

What is EMF?

The electrical action generated by a non-electrical source, measured in volts, is referred to as emf or electromotive force. Devices, such as batteries or generators, generate an emf by converting various sources of energy into electrical energy.

The emf induced in a coil is given by

[tex]\varepsilon = \dfrac{-N \times \triangle \phi}{ \triangle t}[/tex]

where

ΔΦ is the change in magnetic flux, Δt is the change in time, and N is the number of loops.

Given that the initial magnetic flux is -58 Wb while the final magnetic flux is 38 Wb. Also, the change in time is 0.34 seconds and the number of loops is 2. Therefore, the emf induced can be written as,

[tex]\varepsilon = \dfrac{-N \times \triangle \phi}{ \triangle t}[/tex]

[tex]\varepsilon = \dfrac{-(2) \times [38-(-58)]}{0.34}\\\\\varepsilon = -564.7\rm\ V[/tex]

But there are two other interesting coins currently in circulation. Here are some details about those coins. Be on the lookout for these rare beauties and add them to your collection!The DollarThe one-dollar coin is the largest circulating coin; it represents 100 pennies! When you hear the word dollar, you probably think of the basic unit of money in the United States, whether paper or golden coins. But our first dollars were coins made of silver. The word dollar comes from the German word thaler, which was a large silver German coin.Because lots of people around the world used these silver thalers, other countries began making their own versions. American colonists were used to using the Spanish dollar, a coin often used in the nearby lands that traded with the colonies. So dollar was a pretty easy choice as a name for the brand-new currency of the United States.The dollar was one of the first silver coins made in the United States, back in 1794. Over the years, there were times when dollar coins were not made, and people used other denominations. But the dollar coin is back in production again, only it is no longer made of silver. Kennedy half dollars and dollar coins are produced as collectibles, not for everyday transactions. However, they may be still used as legal tender.The coins golden color does not come from gold, but a special mixture of copper, zinc, manganese, and nickel. This mix not only looks golden to human eyes, but looks like the silver-colored Susan B. Anthony dollar to vending machines. Despite their different color, both silvery and golden dollars have the same electromagnetic signature, so they can both be read by the same machines.The 2019 reverse depicts Mary Golda Ross, the first Native American engineer in the U.S. space program. The dollar coins obverse design has included different versions of Liberty and other individuals including President Dwight D. Eisenhower (19711978), suffragist Susan B. Anthony (19791981, 1999), and Sacagawea in 2000. The Presidential $1 Coin Program launched in 2007, and the obverse design has featured different U.S. presidents. The Native American $1 Coin Program, launched in 2009, features Sacagawea.The Half DollarThe current design is based on the Presidential Seal. It consists of an eagle with a shield on its breast holding a symbolic olive branch and a bundle of 13 arrows. A ring of 50 stars surrounds the design.The half dollar is the United States fifty-cent coin. If youve ever seen a half dollar, you probably know it shows President John F. Kennedy on the front. But many other designs have appeared on the half dollar coin over the years.From 1794 to 1947, the half dollar, like most coins of the time, were made of silver and decorated with the head or form of an imaginary woman who stood for liberty. Then Benjamin Franklin became the face on the front of the half dollar. Although he was never president, like the men on our other coins, Franklin was a major force in shaping the United States of America. Below his bust are the initials of John R. Sinnock, who also sculpted the bust on the Roosevelt dime.Soon after the assassination of John F. Kennedy, the late presidents profile took its place on the half dollar.
