Two masses, m1 and m2, are connected by a light rod of length L. Calculate the moment of inertia I of the system with respect to the axis going through mass m1 perpendicularly to the direction of L. Same for m2. Same for the axis going through the center of mass. Which of the results is the smallest?
A two-stage rocket moves in space at a constant velocity of +4940 m/s. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 1000-kg upper stage is +5930 m/s.
n AC voltage of the form ?v = 100 sin 1 000t, where ?v is in volts and t is in seconds, is applied to a series RLC circuit. Find the average power in Watts delivered to the circuit
Find the area of a circle of diameter d and circumference C? Use d for the diameter and C for the circumference. Note that your answer should depend on both d and C but not explicitly on the radius
when two lenses are used in combination the first one forms an image that then serves as the object for the second
One mole of an ideal monatomic gas is taken through the cycle shown in the figure. Assume that p = 3 p0, V = 3 V0, p0 = 1.01×105 Pa, and V0 = 0.0250 m3. Calculate the energy added as heat during stroke abc
Two identical sinusoidal waves by wavelengths of 2.00 m travel in the same direction at a speed of 1.50 m/s. The second wave originates from the similar point as the first, however at a later time. The amplitude of the resultant wave is the similar a..
