The small piston of a hydraulic lift has a diameter of 8.70 cm , and its large piston has a diameter of 44.0 cm. The lift raises a load of 1.50×10^4 N. 1. Determine the pressure applied to the fluid in the lift. P = N/m^2
A 0.700kg block is attached to a spring with spring constant 14.5N/m . While the block is sitting at rest, find The amplitude of the subsequent oscillations
Consider an infant who weighs 100 newtons. During each year she grows so that each dimension of her body increases by 5%. How much would she weigh then.
The diffraction pattern produced by the aperture is observed on a screen at a distance of 4 m from the aperture. The power density at the centre of diffraction pattern is measured to be 7 W/m2.
A space traveler weighs 535 N on earth. What would the traveler weigh on another planet whose radius is three times that of earth and whose mass is twice that of earth.
A small piece of Styrofoam packing material is dropped from a height of 1.50 m above the ground. Until it reaches terminal speed, magnitude of its acceleration is given by a = g - bv. After falling 0.40 m, the styrofoam effectively reaches its ter..
A 2200kg sport utility vehicle travelling at 96 km/h can be stopped in 0.20 s if it hits a concrete wall. Suppose a 60 kg person was in the car that hit this wall. The velocity of the person equals that of the car both before and after the crash a..
The end of the spring is next to the 13 cm mark on the ruler. If a 2.0-kg mass is now attached to the end of the spring, elucidate where will the end of the spring line up with the ruler marks?
