The mass of liquid in the container is 94 grams and the density of the liquid is 0.78 grams/cm³ or 780 Kg/m³.

Given in the question

The volume of the liquid = Volume of the container

                                  =  120 cm³

Total Mass = 145 grams

Mass of the empty Beaker = 51 grams

To find

Mass of the liquid

The density of the liquid

Now,

Total Mass = Mass of LIquid + Mass of the empty Beaker

Mass of LIquid = Total Mass -  Mass of the empty Beaker  

Put in the value, we get

Mass of liquid = 145 - 51 grams

Mass of liquid = 94 grams

Now, Density is the ratio of the mass of the substance and the volume, the substance occupies in the space. It is not a constant value and is variable with the variation in the temperature of the substance. Its S.I. unit is Kg/m³. B ut its other commonly used unit is gram/cm³.

The density of liquid = Mass of the liquid/ Volume of the liquid

Put in the value, we get

The density of the liquid = 94/120  grams/cm³

The density of the liquid = 0.78 grams/cm³ = 780 Kg/m³

Therefore, the mass of liquid in the container is 94 grams and the density of the liquid is 0.78 grams/cm³ or 780 Kg/m³.

The maximum height reached by the baseball is 31.89 m and the time taken to reach there is 1.3 seconds

Linear motions are straight line motions. It can be horizontal motion, or vertical motion which is motion under gravity.

Given that a baseball is hit almost straight up into the air with a speed of 25m/s estimate how high it goes.

At the maximum height, final velocity V = 0

Using third equation of motion, that is, V² = U² - 2gH, we can estimate how high it goes.

0 = 25² - 2 × 9.8 × H

625 = 19.6H

H = 625/19.6

H = 31.89 m

To know how long it is in the air, the factors that make this estimate will be

Speed = s / t

25 = 31.89 / t

t = 31.89 / 25

t = 1.2756

t = 1.3 s

Therefore, the maximum height reached by the baseball is 31.89 m and the time taken to reach there is 1.3 seconds

Energy transformation, also known as energy conversion, is the process of changing energy from one form to another.

The energy of transformation in a proper way is known as the transformation chain. When we boiled water in the kettle, then the water starts to boil so electrical energy is converted into thermal energy. When we drop the water from the kettle into the cup, then the gravitational potential energy is converted into the kinetic energy because the height is involved in it. Generator is the source of electrical energy in which mechanical energy is converted into electrical energy.

The acceleration of the boat is 2.5 m/s².

The weight of a small sailboat is 200 kg.

The accelerating force of the wind on the boat is 707 N northwest and 500 N acting west.

Taking into consideration the wind's accelerating force. It can be visualized as the combination of two elements:

707 /√2 = 500 N acting north, and

707 /√ 2 = 500 N acting east.

It is acting both to the North and to the East because it is supposed to be acting in the Northeast wards. The drag of the keel's eastward component will then cancel out its westward counterpart.

Essentially, 500 N north will then be the result of two forces acting on the boat.

Combining like terms,

24T + 19.6T - 20T = 48 +19.6

23.6T = 67.6

T = 2.86 sec.

In other words, the stone will pass the ball 2.86 seconds after the ball has been tossed (or 0.86 sec after the stone has been tossed).

Solving for Sb,

Sb = 20(2.86) - (1/2)(9.8)([tex]2.86^2[/tex])

The buoyancy of a boat and the density of the materials used in its construction have an impact on the connection between its volume and the amount of mass it can support before sinking.

Thus, The buoyancy principle asserts that the upward force a fluid (in this case, water) exerts on a submerged or floating item is equal to the weight of the fluid displaced by the object, which is why a boat floats in water.

A boat moves as much water as its own volume while it is submerged in water.

A boat will float if its total weight, including its passengers and cargo, is less than the weight of the water it moves.

1 The ball travel 58.29 m high

2. The time the ball spend in the air is 8.67 s

The maximum height reached by the ball can be obtained as follow:

v² = u² – 2gh (since the ball is going against gravity)

0² = 33.8² – (2 × 9.8 × h)

0 = 1142.44 – 19.6h

Collect like terms

0 – 1142.44 = –19.6h

–1142.44 = –19.6h

Divide both side by –19.6

h = –1142.44 / –19.6

h = 58.29 m

We'll begin by calculating the time to reach the maximum height . This can be obtained as follow:

v = u – gt (since the ball is going against gravity)

0 = 33.8 – (9.8 × t₁)

0 = 33.8 – 9.8t₁

Collect like terms

0 – 33.8 = –9.8t₁

–33.8 = –9.8t

Divide both side by –9.8

t₁ = –33.8 / –9.8

t₁ = 3.45 s

Next, we shall determine the time take to fall to the ground

h = ½gt²

133.29 = ½ × 9.8 × t₂²

133.29 = 4.9 × t₂²

Divide both side by 4.9

t₂² = 133.29 / 4.9

Take the square root of both side

t₂ = √(133.29 / 4.9)

t₂ = 5.22 s

Finally, we shall determine the time spend by the ball in the air. This is shown below:

T = t₁ + t₂

T = 3.45 + 5.22

The Moment of inertia of the cylinder is equal to 8.82 Kgm².

The propensity of a force to produce or modify the rotational motion of a body is known as torque, also known as moment, or moment of force. It is a force that causes an object to twist or turn. Force and distance are multiplied to calculate torque. It has both a direction and a magnitude because it is a vector quantity. Newton-meters, or N*m, is the torque unit in the SI system.

A spinning object's change in angular velocity per unit of time is expressed quantitatively as angular acceleration, also known as rotational acceleration. It has a vector form.

Given in the question

Torque = 75 Nm

Angular acceleration = 8.5 rad/s²

Torque = Angular acceleration × moment of inertia

Since the graph provided represents voltage and current data for resistor R, the resistance of R is 2.0 Ω

The resistance of a metallic material is its opposition to the flow of electric current.

Resistance is given by R = V/I where

To find the resistance of R, we take the gradient of the graph since reistance R = V/I.

So, the resistance R = ΔV/ΔI where

R = ΔV/ΔI

= (V' - V)/(I' - I)

Taking points from the graph

So, substituting the values of the variables into the equation, we have

R  = (V' - V)/(I' - I)

= (9.0 V - 0 V)/(4.5 A - 0 A)  

= 9.0 V/4.5 A

Answer:

200m west

Explanation:

Displacement = v.t where v is the velocity of the object ad t = time

At 50m/hr for 4 hours

Displacement = 50 x 4 = 200m west of origin

The total displacement of the object was 7.5 meters.

There's a relation between the common movement analysis graphs that we can always use. These relations are the following:

The derivative (slope) of a displacement vs. time graph gives you the function of speed vs. time. Also, when you take the speed vs. time graph and find its derivative, you will get the acceleration function of the observed body.

Now, doing to opposite of derivation (integration), we are able to calculate the displacement of an object when we integrate the function of velocity vs. time. This is not a complicated process when we have a linear function, because integration is just calculating the area under the curve or line of a graph.

In this case, the graph forms a right triangle with the x axis, therefore, we are able to calculate displacement by finding the area under the line of the graph. It could also be made with integration, we are going to do it with both processes as they are both used, and in some cases you have to strictly use one of the 2 in order to get the most precise answers.

When we observe the line, we can crearly tell that the area under the graph constitutes a right triangle. Hence, the area under the graph is given by the following formula:

[tex]A=\frac{bh}{2}[/tex]

Substitute the values and calculate.

(Check attached image 1 to see where the values of b and h are taken from).

[tex]A=\frac{(5)(3)}{2}\\ \\A=7.5[/tex]

Hence, the total displacement of the object was 7.5 meters.

In this method, we'll need to find the equation of the line and then generate and solve a definite integral.

Take 2 points from the line.

(0, 0) and (5, 3).

Find the slope.

Answer:

Explanation:

Given average acceleration a and initial velocity  v0 we can compute the final velocity  using the equation

a = (v - v0)/t where t is the time taken to reach final velocity from initial velocity

Here a = 2 m/s² and v0 is the initial velocity when she passes her younger brother v0 = 5m/s.

It takes t = 4 s to pass her older brother at which time her speed is v, say

Then

a = (v - v0)/t

Plugging in known values,

2 = (v - 5)/4

Switch sides:
(v- 5)/4 = 2

Multiply both sides by 4:
v - 5  = 8

v =5 + 8 = 13 m/s - the speed at which she passes her older brother
