A heavy planet and a light planet are found to have the same momentum.

Physics

Licemer1 [7]3 years ago

•The light planet is faster,

Explanation:

Since we have two planets whose momentum have been found to be the same, and we know that one has a higher mass than the other, then the light planet can be said to be faster moving.

This way, the momentum of the light planet can measure up.

  • Momentum is the product of mass and velocity of a body.

Momentum = mass  x velocity

 If a body is heavier than another, it will have more mass than it.

To compensate for the momentum, the lighter body must have a higher velocity.

This way, their momentum will be the same.

What is the direction of propagation of the wave if E⃗ =Ei^,B⃗ =−Bj^. Express the direction of the propagation vector, P⃗ , as a
nataly862011 [7]

Answer with Explanation:

We are given that

Electric field vector=\vec{E}=E\hat{i}

Magnetic field vector=\vec{B}=-B\hat{j}

We have to find the direction of propagation of the wave.

We know that  

The direction of propagation of wave=\vec{E}\times \vec{B}

The direction of propagation of wave=\hat{i}\times (-\hat{j})=-\hat{k}

Because (\hat{i}\times \hat{j}=\hat{k})

The  wave propagate in -z direction.

Therefore, the component of the vector is (0,0,-1).

Hence, the direction of the propagation of wave is - z direction and component of direction of propagation vector is (0,0,-1).

At a waterpark, sleds with riders are sent along a slippery, horizontal surface by the release of a large, compressed spring. Th
steposvetlana [31]

The sleds speed when the spring returns toits uncompressed length is v = 0.03 m/s.

<u>Explanation</u>:

Given,

force constant = 42 N/cm = 0.42 N/m,   mass m = 68 kg, spring x = 0.39 m

The potential energy, U, stored in the spring is

                     U = 1/2 kx^2  

                       = 1 / 2 \times 0.42 \times (0.39)^2

                       = 0.032 J

All its potential energy has been converted into kinetic energy since it has a uncompressed length.

                    K = 1/2 mv^2

                     v = sqrt (2K / m)

                       = √(( 2 \times 0.032) / 68)

                    v = 0.03 m/s .

Jlenok [28]

Answer:

acceleration m/s²

Explanation:

The units on the left side of the equation are units of length. The units on the right side of the equation must be units of length also. Acceleration times time squared gives length.

If gravity did not affect the pain of a horizontally thrown ball the ball would
Drupady [299]

If gravity had no effect on a ball after you threw it ... and there also
were no air to slow it down ... then the ball would continue traveling
in a straight line, in whatever direction you threw it. 

That's the heart and soul of Newton's laws of motion ... any object
keeps moving at the same speed, and in a straight line in the same
direction, until a force acts on it to change its speed or direction.\

If you threw the ball horizontally, then it would keep moving in the
same direction you threw it.  But don't forget:  The Earth is not flat.
The Earth is a sphere.  So, as the ball kept going farther and farther
in the same straight line, the Earth would curve away from it, and it
would look like the ball is getting farther and farther from the ground.
