Consider two planets, a and b, orbiting a distant star. planet b orbits twice as far from the star as planet a does. how does planet b's orbital period compare to planet a's?

Why are concepts in physics described in formulas?

While running at a constant velocity, how should you throw a ball with respect to you so that you can catch it yourself?

Suppose that 2J of work is needed to stretch a spring from its natural length of 30cm to a length of 42cm how much work is needed to stretch the spring from 35 to 40cm So Hookies law Work = kx^ (2) I get k = 2/144

A 4.25 kg block is sent up a ramp inclined at an angle theta=37.5° from the horizontal. It is given an initial velocity?0=15.0 m/s up the ramp. Between the block and the ramp, the coefficient of kinetic friction is? k=0.

Will Upvote! If the mass of two objects increases, the force of gravity between them increases decreases remains the same could increase or decrease, depending on the shape of the objects

A farmer had 15 sheep, and all but 8 died. How many are left?

While playing with her 5 year old cousin, a Physics 135 student pushed him forward on his scooter. She pushes with a force of 50 Newtons for 3.5 seconds. If the boy and the scooter together have a mass of 30 kg, what is their final velocity? a. 2.

3. A 120.0 V generator supplies 3.0 kw of power. How much current ca the generator deliver?

An apple drops from a tree and hits the ground in 1.5s what is its speed just before it hits the ground?

Sound travels slow in cold air. Why does the speed of sound depend on air temperature?
