Answer:
A. kinetic energy
B. angular velocity
E. angular position
Explanation:
The quantities that cannot be constant if a constant net torque is exerted on an objecta are:
A. Kinetic energy. If a torque is applied, the linear or angular speed will be changing at a rate proportional to the torque, so the kinetic energy will change too.
B. Angular velocity. It will change at a rate equal to the torque.
C. Angular position. If the angular velocity changes, the angular position will change.

In circuits, the average power is defined as the average of the instantaneous power over one period. The instantaneous power can be found as:
So the average power is:
But:
So:

In terms of RMS values:
The liver, because its liver cancer.. lol
The liver filters your blood, without it, your blood will stay 'dirty' and cannot do its jobs like it usually should be
Answer:
Explanation:
Average speed is distance traveled over time taken to do so
home to station
d = 60 km
t = 60 km/60 km/hr = 1 hr
station to shop
d = 60 km
t = 60 km / 120 km/hr = ½ hr
speed
s = (60 + 60) / (1 + ½) = 120/1.5 = 80 km/h
