What is the ability of the body to function successfully and effectively during physical activity

A 72-kg boy is surfing and catches a wave which gives him an initial speed of 1.6 m/s. He then drops through a height of 1.61 m, and ends with a speed of 8.5 m/s. How much nonconservative work (in kJ) was done on the boy

If weight is a measure of an object's force due to gravity, what is the weight of a student who has a mass of 65 kg? (assume that the acceleration due to gravity equals 9.8 m/s2.)

You are trying to experimentally determine the electric potential of a conducting sphere, which you know is given by V=kQ/r. You experimentally measured the charge to be Q=3.2042e-19 C and the radius to be r=0.

Find the speed required to throw a ball straight up and have it return 6 seconds later. neglect air resistance. how high does the ball go?

Do all electromagnetic waves travel at the speed of light, carry energy, and travel through a vacuum?

The voltage across the primary winding is 350,000 V, and the voltage across the secondary winding is 17,500 V. If the secondary winding has 600 coils, how many coils are in the primary winding? 30 583 12000 332500

A 200 watt t. v. is used for 20 hours in a week. If it is used for four weeks then what is cost of electricity if rate is 5rs/kwh
