For volleyball a dead ball is, A ball not in play following a point, side-out or any other decision of the referee temporarily suspending play.
For basketball the ball is considered dead, such as when a foul has been committed and called by a referee, a foul shot has been attempted and another one is yet to be attempted, or the ball has gone out of bounds. Player substitutions may then be made.
Answer:
A) Walking would burn up more energy
B) Walking: 1,914,000 J
Running: 1,386,000 J
C) Even though running is more intense and burns energy at higher rate, it burns energy for a much shorter time than walking.
Explanation:
Watt is a unit for power that is equivalent to Joules per second (J/s). Therefore, to figure out the energy burnt up during an activity, first we need to know how long (in seconds) that activity took.
1- Running
V = 10.0 km/h
d = 5.50 km
t = 5.50/10 = 0.55 h = 0.55(h) *60 (min/h) *60(s/min) = 1,980 s
2- Walking
V = 3.0 km/h
d = 5.50 km
t = 5.50/ = 1.83333 h = 1.83333(h) *60 (min/h) *60(s/min) = 6,600 s

Answer:
im pretty sure thats called friction, or did you mean something else?
<span>GPE= mgh = 0.1 kg * 9.8 m/s^2 * 12.5m = 12.25 J</span>
