Explanation:
Given
radius of wheel 
mass of wheel 
Force 
Moment of Inertia of solid wheel 
Torque is given by
Force on the axle is 32 N since there is no linear acceleration of the system
using Third law F=32 N
Torque of the axle applied to the wheel is zero because force of axle imparted at the center of axle
Answer:
The rate of acceleration is 7.441 m/s/s.
(19 - 2.6) * 9.8 / (19 + 2.6) = 7.441
The tension in the cord is 44.826 Newtons.
2.6 * (9.8 + 7.441) = 44.826
or
19 * (9.8 - 7.441) = 44.826
Explanation:
Answer:
Circulatory System
Explanation:
The respiratory system works with the circulatory system to provide tis oxygen and to remove the waste products of metabolism. It also helps to regulate PH of the blood. Respiration is the sequence of events that result in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
Answer:
cold air is more dense than warm water so it sinks to the bottom of the pool
