Just before opening her parachute a skydiver of mass 50 kg reaches terminal velocity. calculate the force of air resistance

Terminal velocity is described as a velocity attained when an object which falls freely experiences 0 net force owing to gravitational force which is balanced by the resistance of the air. Hence, there is no acceleration thus, the velocity is constant. In order to attain terminal velocity by the skydiver, the weight of the skydiver must be equal to the resistance of the air hence we  have the equation below;

50 kg*9.8 m/s²= 490 Newton.

Summarily, the force or magnitude of the air resistance is 490 Newton

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
