1) A 15-kg iron ball is dropped onto a pavement from a height of 80m. Suppose half of the heat generated goes into warming the ball. What is the temperature increase of the ball in degree C? (the specific heat of iron in SI is 450J/kg*C) Why is the answer the same for an iron ball of any mass? Show equations and work.
Which has a greater packing fraction, a diamond crystal structure or a copper crystal structure, how much empty space would be left in each structure
Two traveling sinusoidal waves are described by the wave functions, What is the amplitude of the resultant wave, What is the frequency of the resultant wave
The pressure in the fluid at the distance from the axis of rotation is. You may ignore the variation in pressure with depth; suppose that it is much smaller than the variation in pressure with radius.
A 41 kg crate, starting from rest, is pulled across a floor with the constant horizontal force of 250 N. For the first 10m the floor is frictionless, and for the next 11.00 m the coefficient of friction is 0.17. What is the final speed of the crat..
The electric field points radially outward at all points within the sphere (and outside too, for that matter). What is the strength of the electric field at a distance r from the center, inside sphere.
Diffracted light from a circular aperture is viewed on a distant viewing screen, Find the radius of the aperture if the wavelength of light is 680 nm
An 86 Kg person stands on a uniform ladder 4m long, that weighs 70N. The floor is rough; hence, it exerts both a normal force, and a frictional force, on ladder. The wall, on the other hand, is frictionless; it exerts only the normal force. What a..
