Answer:

An asteroid is a minor planet of the inner Solar System. Historically, these terms have been applied to any astronomical object orbiting the Sun that did not resolve into a disc in a telescope and was not observed to have characteristics of an active comet such as a tail.

The conditions necessary for an astronomical apocalypse are the shifting of earth from its orbit and collision of big star with earth.

The apocalypse event occurs due to climatic, nuclear war, plague or virus, zombie apocalypse or alien invasion but astronomical apocalypse occurs due to the shifting of earth from its orbit and collision of big star with earth.

So we can conclude that the conditions necessary for an astronomical apocalypse are the shifting of earth from its orbit and collision of big star with earth.

Answer:

The magnitude of the average force to supply to the ball in order to stop the ball is 9.68 N.

Explanation:

Let's think Newton's 2nd Law: F = ma.

We are given the mass of the ball: 219 g ⇒ .219 kg.

We are given the initial velocity, time, and final velocity of the ball ∴ we can solve for acceleration.

We are trying to find the force needed to stop the ball.

Let's find the acceleration of the ball first.

Now, we can plug these known values into this kinematic equation and solve for acceleration, a.

Substitute acceleration and mass into F = ma and solve for the force.

The magnitude of the average force to supply to the ball in order to stop the ball is 9.68 N.

Most stars in the Milky Way's halo are very old

very oldThere is no recycling of gas in the halo, so halo stars are quite old.

The requried, "Most stars in the Milky Way's halo are very old."

The Milky Way halo is a large, spherical region surrounding the disk of the galaxy, and it is believed to be composed primarily of ancient stars that formed early in the history of the galaxy.

Here,

These stars are typically metal-poor, which means they have lower abundances of elements heavier than hydrogen and helium compared to stars in the disk. They are also old, with estimated ages of several billion years or more.

The halo stars are believed to have formed in small, isolated systems that were later accreted by the Milky Way. They are widely dispersed and do not form dense concentrations like those found in the disk or in globular clusters.

Based on the fact that the student is moved twice as far from the center of the earth, her new weight will be 112.5 N.

When the student was moved by the same distance from the center of the earth, her weight was halved.

When she was then moved twice as far, her weight was halved again.

This means that her new weight is:

= 450 x 1/2 x 1/2

= 450 x 1/4

The principle of cause and effect is applied in every life as is seen in damage caused to cells by exposure to large amounts of ultravoilet rays.

Cause and effect refers to the principle in which for every effect received or observed, an underlying cause is present.

Based on cause and effect;

Cells can repair small amounts of damage caused when a person is exposed to large amounts of gamma rays.

If a certain amount of exposure time in the sun is dangerous for adults, would result in a similar damage to a child.

A lot of sun exposure over time will cause an individual to develop a high risk of cell damage just as a shorter exposure time to X-rays gives the same risk.

Ultraviolet light can damage a cell especially with over 5 minutes of exposure to UVB light.

New vaccine studies are sometimes tested on pigs because humans have an immune system very similar to pigs.

Constructive interference in performance halls and the elimination of echoes are reasons why choir concerts better in performance halls than in gymnasiums.

Constructive interference is a phenomenon which occurs when two waves travelling in same direction and which are in phase add up together to produce a wave of greater amplitude.

Constructive interference occurs in performance halls while destructive interference occurs in gymnasiums.

Also in performance halls, echoes are minimized due to the padded walls and the curtains while echoes which disturb choir concerts occur in gymnasiums.

Therefore, choir concerts better in performance halls than in gymnasiums because of constructive interference in performance halls and the elimination of echoes.

force to stop it is the same number

PE = mgh = .5 *9.81  *  .75 =

     doubling height will double PE

2 x 10^6  =  40 * 9.81  *  h      sove for 'h' in meters  

Initial kinetic energy is 11250 J and magnitude of force to stop bullet is 75 N.

The GPE for 0.75m height floor is 3.75J.

The GPE for double of 0.75m height is 7.5J.

The high on which 40 kg mass is lifted is 5000m.

The kinetic energy of an object is the energy that it possesses due to its motion.

Answer:

B. Crest

Explanation:

The high point of a transverse wave is a called the crest.

Answer:

Actually, there is  no force (felt by the object) acting on the object.

It is similar to an  object in orbit around the earth (weightlessness)

F = M a    describes the motion of the particle where

M a = M g    where the acceleration of the particle is equal to the force of gravity acting on the particle

From an external view the only force acting on the particle is M g and it produces an acceleration of M g

There is no force felt by the freely falling body. The cause of free fall is gravitational pull. Where Acceleration is equal to the gravitational acceleration. According to Newton's Law of Gravitation , two bodies attract each other due to their masses and separation , since earth is a very big body therefore the lit body falls towards the earth . Thus the graph plotted is a straight line.

What is Newton's law of Gravitation?

"The force acting between two bodies is directly proportional to product of masses and inversely proportional to the square of the separation ."

F= G.{m_{1} . m_{2} }/r^{2}.

Hence the only force by which the object is falling is gravitational pull.

Answer:

temperature is essentially the speed of the molecules.

Explanation:

temperature is the kinetic energy of molecules, and kinetic energy is dependent on velocity.

Answer:

Initial momentum: [tex]0\; {\rm kg \cdot m \cdot s^{-1}}[/tex].

Final momentum: [tex]150\; {\rm kg \cdot m\cdot s^{-1}}[/tex].

Force on the mass (assuming that the force is constant): [tex]75\; {\rm N}[/tex].

Impulse on the mass: [tex]150\; {\rm kg \cdot m \cdot s^{-1}}[/tex].

Explanation:

The momentum [tex]p[/tex] of an object is equal to the product of mass [tex]m[/tex] and velocity (a vector) [tex]v[/tex].

The initial momentum of this mass was [tex]0\; {\rm kg \cdot m \cdot s^{-1}}[/tex] since the velocity of this object was initially [tex]0\; {\rm m\cdot s^{-1}}[/tex].

At [tex]v = 3\; {\rm m\cdot s^{-1}}[/tex], the momentum of this mass ([tex]m = 50\; {\rm kg}[/tex]) would be:

[tex]\begin{aligned}p &= m\, v \\ &= 50\; {\rm kg} \times 3\; {\rm m\cdot s^{-1}} \\ &= 150\; {\rm kg \cdot m \cdot s^{-1}}\end{aligned}[/tex].

Assume that the external force [tex]F[/tex] on this mass is constant. By Newton's Second Law of motion, the external force on this mass would be equal to the rate of change in the momentum of this mass.

Since the momentum of this mass increased by [tex]\Delta v = 150\; {\rm kg \cdot m \cdot s^{-1}}[/tex] in [tex]\Delta t = 2\; {\rm s}[/tex], the external force on this mass would be:

[tex]\begin{aligned}F &= \frac{\Delta v}{\Delta t} \\ &= \frac{150\; {\rm kg \cdot m \cdot s^{-1}}}{2\; {\rm s}} \\ &= 75\; {\rm kg \cdot m \cdot s^{-2}} \\ &= 75\; {\rm N}\end{aligned}[/tex].

The impulse of an external force on an object is equal to the change in the momentum of that object. Since the change in momentum of this mass was [tex]\Delta v = 150\; {\rm kg \cdot m \cdot s^{-1}}[/tex], the corresponding impulse would also be [tex]150\; {\rm kg \cdot m\cdot s^{-1}}[/tex]:

[tex]\begin{aligned}J &= \Delta v \\ &= 150\; {\rm kg \cdot m\cdot s^{-1}} \\ &= 150\; {\rm N \cdot s}\end{aligned}[/tex].

Answer:m1v1 + m2v2 = (m1f + m2f)vf. 3000kg(10.0m/s) + (15000kg)(0.0m/s) = (18000kg)(vf).
