Two football players are running next to each other on a football field in a straight line from one end of the field to the other end . As they are running one of the football players is carrying a heavy weight and decides to throw the weight to the other player . If neither football player exerts any force perpendicular to their direction of motion , which of the following choices is correct about their motion after the weight is thrown and caught by the other football player ?

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

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?
