If the Sun were twice as massive, its pull on Mars would be A. unchanged. B. twice. C. half. D. four times as much.

How is temperature defined in terms of molecular action?

How do you increase kinetic energy of an apple

How does increasing the amount of charge on an object affect the electric force it exerts on another charged object?

A Thomson's gazelle can run at very high speeds, but its acceleration is relatively modest. A reasonable model for the sprint of a gazelle assumes an acceleration of 4.2 m/s2m/s2 for 6.5 ss, after which the gazelle continues at a steady speed.

A tuning fork produces a sound wave on air with a frequency of 261.6 hz. at room temperature the speed of sound is 343m/s. what is the wave length

the acceleration of gravity is 28 times on sun than earth. Imagine there is a space suit that let you stand on sun. Calculate the weight of 100 kg person on earth in newtons

A force of 20 n acts upon a 5 kg block, calculate acceleration of the object

What resultant force is needed to accelerate a train of mass 3.41000000 kg from rest to 15.0ms in exactly 20s
