Answer:
The net torque about the pivot is and the answer is 'c'
c. 
Explanation:
The torque is the force apply in a distance so it is the moment so depends on the way to be put it the signs so:
Now to find the net Torque is the summation of both torques
Answer:
warmer air
Explanation:
the particles are more excited which increases the probability that the particles will bump into each other
Explanation:
Speed is distance over time.
500 km / 2 hr = 250 km/hr
Velocity is speed and direction.
250 km/hr north
Answer:
Due to Conservation of Energy just as the ball hits the ground it's potential energy is assumed zero
Therefore disregarding air resistance all energy is converted into potential energy.
So KE = PE
(5 J)
Answer:
Since velocity is a speed and a direction, there are only two ways for you to accelerate
Explanation:
change your speed or change your direction—or change both.
