An incident ray and the corresponding reflected ray are mutually perpendicular on each other. calculate the angle of reflection and angle of incidence ray.
A bicycle wheel has a mass of 1.5 kg and a radius of 0.3 m. Ignore the mass of the spokes of the wheel. What is the angular velocity and the tangential velocity of the wheel after 4.0 sec
Oxygen in the Lungs: In the lungs, the respiratory membrane separates tiny sacs of air (pressure1.00x105Pa) from the blood in the capillaries. These sacs are called alveoli. The average radius of the alveoli is 0.125 mm, and the air inside contains 1..
If each spring is stretched 300 mm, determine the mass m of each block. Neglect the weight of the pulleys and cords. The springs are unstretched when d = 2 m.
Estimate the volume of your body. (Consider your body to be a cylinder having a radius of about 6 inches ( or 0.15m and a height of about 1.5 meters)
