1.) A thin, rectangular sheet of metal has mass M and sides of length a and b. Find the moment of inertia of this sheet about an axis that lies in the plane of the plate, passes through the center of the plate, and is parallel to the side with length b.
I = ?
2.) Find the moment of inertia of the plate for an axis that lies in the plane of the plate, passes through the center of the plate, and is perpendicular to the axis in part A.
Oasis B is located 25 km east from oasis A. A camel starts from oasis A and travels 19.6 km in the direction 14.7 degrees south of east. Then it walks 8 km directly to the north. How far is the camel from oasis B?
What should the charge (sign and magnitude) of a particle of mass 1.487 be for it to remain stationary while placed in a downward-directed electric field of magnitude 630.
A satellite is circling a small planet at a speed of 3.60 rev/day. If the satellite's orbit has a diameter of 30,000 km, how fast is the satellite moving
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.
he box is taken up a mountain where the air pressure outside the box is 8.00 104 Pa. The inside of the box is completely evacuated. Illustrate what is the magnitude of the force required to pull the lid off the box?
The 4 block in the figure is attached to a vertical rod by means of two strings. When the system rotates about the axis of the rod, the strings are extended and the tension in the upper string is 77.
Find out the translational speed at the bottom of the fall where it is horizontal. Ignore the frictional losses and assume mass of the cylinder is distributed uniformly.
A string of mass 0.0003kg/m and 0.5m long is vibrating 200 cycles per second. What must be the tension? What hanging mass would generate this tension? I got 12N for tension. Is this correct? And how would you solve for hanging mass.
What is the rotational kinetic energy of the Earth? Use the moment of inertia you calculated in Part A rather than the actual moment of inertia given in Part B.
The Large Hadron Collider, or LHC, to be completed later this year, accelerates protons around a nearly circular track of circumference 26.66 km to a momentum of up to 3.74e-15 kg m/s, For the same magnetic field as in part (a), what is the momentu..
What is the distance between the centers of the two slits? Describe answer in m.
