Answer:

Force

Explanation:

Force is a push or pull which can change the state of body whether it is rest or in motion or tries to change the state of body.

Force is equal to the rate o change of momentum of body.

Three cars, car x, car y, and car z, begin accelerating from rest, at the same time. car x is more massive than car y, which is

grigory [225]

When the net force exerted on each car is identical. after 10 seconds, the amount of momentum is same for all cars.

<h3>What is impulse?</h3>

The change in momentum is equal to the product of impact force applied while colliding and time for that impact.

F. t = m (Vf -Vi)

where, Vf is the final velocity and Vi is the initial velocity.

For car X, Fx x t = Mx Vx

For car Y, Fy x t = My Vy

For car Z, Fz x t = Mz Vz

The force applied is same for all and the the time is also same equal to 10 seconds. The impulse is same for all the cars.

Thus, the three cars have same momentum.

In 1929 Edwin Hubble used a telescope to discover the movement of galaxies. True or false

larisa86 [58]

Explanation :

Edwin Hubble used a telescope to discover the movement of galaxies in 1929. He was an American Astronomer.

The telescope invented by him is called a Hubble telescope. It has a 2.4-meter mirror.

He gives the relation between the distance to a galaxy and its recessional velocity. This is known as the Hubble law. The relation is as follows :

$v=H_0\ r$

where,

$v$ is recessional velocity.

$H_0$ is Hubble constant.

$r$ is distance.

<em>So, the given statement is True.</em>
