When a diffraction pattern of a crystalline solid is recorded using an X-ray beam of wavelength 0.26 nm, the first order diffraction peak occurs at a scattering angle of 35°. If the error in the measurements of angle and wavelength are 1° and 0.01 nm respectively, then determine the error in…
Athlete jumps horizontally from a platform 10.0 m above the water at a speed of 2.00 m / s. (a) At a distance of 0.800 s after the jump, how far will the athlete be horizontally from the platform? (b) also at what point will the athlete be above the water at this point? (c) What is the…
A raindrop with radius R = 1.5 mm falls from a cloud that is at height h = 1200 m above the round. The drag coefficient C for the drop is 0.60. Assume that the drop is spherical throughout its fall. The density of water is 1000 kg/m 3 , and the density of air is 1.2 kg/m 3 . What is the…
A 3.5 kg block is pushed along a horizontal floor by a force of magnitude 15 N at an angle of 40 with the horizontal (figure 1). The coefficient of kinetic friction between the block and the floor is 0.25. Calculate the magnitudes of (a) the frictional force on the block from the floor…

A proton (mass 1 u) is shot toward an unknown target nucleus at a speed of 2.20×106 m/s . The proton rebounds with its speed reduced by 25% while the target nucleus acquires a speed of 2.96×105 m/s . What is the mass, in atomic mass units, of the target nucleus?
A 6090 kg space probe moving nose-first toward Jupiter at 105 m/s relative to the Sun fires its rocket engine, ejecting 80.0 kg of exhaust at a speed of 253 m/s relative to the space probe.What is the final velocity of the probe?
The figure below shows a cylinder filled with an ideal gas, which has a movable piston resting on it. The cylinder's volume is initially 5.50 L, Iwhen a force on the piston of F = 30.5 kN pushes the piston downward a distance d = 0.125 m, until the volume of the cylinder is 3.00 L. Theprocess…
