Acylindrical capacitor is made of two thin-walled concentric cylinders. the inner cylinder has radius 8 mm , and the outer one a radius 12 mm . the common length of the cylinders is 156 m . what is the potential energy stored in this capacitor when a potential difference 7 v is applied between the inner and outer cylinder? (k =1/4∗π∗ϵ0=8.99×109n⋅m2/c2)

Aplane flying horizontally at an altitude of 1 mile and a speed of of 500mih passes directly over a radar station. find the rate at which the distance from the plane to the station is increasing when it is 2mi away from the station.

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?
