The brightness of stars depends on its distance from earth. Stars that are closer look brighter. Star stuff is my favorite thing to learn about because I'm a sweaty nerd, so if you have anymore related questions I'd love to answer them.

The apparent brightness of a star depends on how bright it really IS, and also on its distance from Earth.  Just like matches, flashlights, and fireflies, stars that are closer to us look brighter to us.  (Think about the Sun.)

On a straight horizontal track along which blocks can slide with negligible friction, block 1 slides toward block 2, which is in
vivado [14]

If the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.

<h3>What is momentum?</h3>

The momentum of an object in motion is the product of mass and speed of the object.

P = mv

<h3>Conservation of linear momentum</h3>

The principle of conservation of linear momentum states that, the sum of the initial momentum must be equal to the sum of the final momentum.

m_1v_1 = m_2 v_2

Thus, if the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.

A 43-N crate is suspended from the left end of a plank. The plank weighs 21 N, but it is not uniform, so its center of gravity d
lesya [120]

Answer:

d_{2}=0.585m

Explanation:

The torque is the force by the distance so to determinate that both torque are the same magnitude so

T_{1}-T_{2}=0

T_{1}=T_{2}

F_{1}*d_{1}=F_{2}*d_{2}

43N*0.30m=21N*d_{2}

Solve to d2

d_{2}=\frac{41N*0.30m}{21N}

d_{2}=0.585m
