Q. Determine the shear strain that results if a force of magnitude 1.10×10^6 N is applied to the top square face of the plate, parallel to side, and a force of equal magnitude is applied in the opposite direction to the bottom face of the plate.
Q. A 130-g baseball, moving along the x-axis with speed 29.0 m/s strikes a fence at a 45 degree angle and rebounds along the y-axis with unchanged speed. Give x and y components of its change in momentum.
How long does this pendulum take for one oscillation? Presume that all displacement angles are small.
A broad beam of light of wavelength 485nm is incident at 90° on a thin, wedge-shaped film with index of refraction 1.50. An observer intercepting the light transmitted by the film sees 17 bright and 16 dark fringes along the length of the film. By..
What was an initial speed of the ball
A 2 kg object is attached to a spring and placed on a horizontal, smooth surface. A horizontal force of 20.0 N is needed to hold the object at rest when it is pulled 0.200 m from its equilibrium position.
The difference in potential between the accelerating plates of a TV set is about 26000 V. If the distance between these plates is 1.5 cm, find out the magnitude of the uniform electric field in this region.
For the 4-particle system find the moment of inertia about the y-axis, that passes through the two masses on the left-hand side of the system.
A river flows due east at 1.50 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 15 m/s due north relative to water.
A block of mass 0.570 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. The force constant of the spring is 450 N/m.
Three equal point charges, each with charge 1.15 , are placed at the vertices of an equilateral triangle whose sides are of length 0.600 . What is an electric potential energy of the system? (Take as zero the potential energy of the three charges ..
The radius of a proton is 0.9e-15 m; suppose that if the particles touch, the distance between their centers will be twice that. What will be the total kinetic energy of both particles an instant before they touch.
What is the beat frequency in Hz. A force of magnitude P pushes the block forward and downward as shown in the figure below. suppose the force is applied at an angle of 24.0° below the horizontal.
A Carnot engine whose cold reservoir temperature is 1.0 C has a thermal efficiency of 40%. By how much should the temperature of the hot reservoir be increased to raise the efficiency to 60%?
