Q. Four astronauts are in the spherical space station.
1) If, as is typical, each of them breathes about 500 {rm{ cm}}^3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year?
2) What would the diameter (in meters) of the space station have to be to include all this air?
A box of books weighing 334 N is shoved across the floor by a force of 479 N exerted downward at an angle of 33° below the horizontal. What is the maximum coefficient of kinetic friction between the box and the floor that allows the box to move with ..
What is the magnitude of displacement
What is magnitude of the force that a concrete support exerts on the bridge at each end. The cloth exerts a friction force of 0.100 N on the mug and the cloth is pulled with a constant acceleration of 3.00 m/s.
Calculate the force required to move an object.
Next you eliminate the 11 kg mass, place the rod horizontally, and strike one end with a hammer. How much time t would elapse before a microphone at the other end of the bar will detect a disturbance.
Estimate how many times planet has orbited its star
What mass (in grams) of steam at 100°C should be mixed with 257 g of ice at its melting point, in the thermally insulated container, to produce liquid water at 84.0°C.
Sketch the shear force and bending moment diagram and Verify that the support reactions are correct.
A steel beam that is 7.00m long weighs 330N. It rests on two supports, 3.00m apart, with equal amounts of beam extending from each end. Suki, who weighs 505 N, stands on the beam in the center and then walks toward one end. How close to the end can s..
At one point in a pipeline, water's speed is 3.30 m/s and the gauge pressure is 4.00×10^4 Pa. Find out the gauge pressure at a second point in the line 13.0 m lower than the first if the pipe diameter at the second point is twice that at the first.
An observer on the ground watches the boy throw the can and catch it. In this observer's ground frame of reference, explain the shape of can's path and determine the initial velocity of the can.
