27. calculate the impulse when an average
force of 10 n acts on a cart for 5.0 s.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
