QUESTION 1: Find the speed of an electron that has a kinetic energy of 1.48 eV. 1 eV = 1.602 × 10^?19 J.
QUESTION 2: Calculate the speed of a proton with a kinetic energy of 1.48 eV.
Coherent light with wavelength 603 passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00 from the slits.
After the Sun exhausts its nuclear fuel, its ultimate fate might be to collapse to a white dwarf state. In this state, it would have about the same mass as it has now, but its radius would be equal to the radius of the Earth.
A merry-go-round starts from rest and accelerates uniformly over 23.5 s to the final angular velocity of 6.55 rev/min.
What is the capacitance of this capacitor. Estimate the terminal speed of a wooden sphere (density 0.810 g/cm3) falling through air, if its radius is 8.00 cm and its drag coefficient is 0.5.
A proton, initially traveling in the +x-direction with a speed of 5.00×105m/s, enters a uniform electric field directed vertically upward, What is the strength of the electric field
A cardboard tube of radius R and length L has a uniform charge density on its surface. Find the potential at a point on the axis of the tube at a distance d from the center.
The potential difference between the plates of a capacitor is 180V. Midway between the plates; a proton and an electron are released. The electron is released from rest.
A ship sets out to sail to a point 141km due north. An unexpected storm blows the ship to a point 138 km due east of its starting point. (a) How far (in km) and (b) in what direction (as an angle from due east, where north of east is a positive an..

How much energy is lost through the walls of the hot water heater in one week? (Assume thinner surface of the heater is 90 C and the outer surface is 27 C.)
Evaluate if the ball clears the crossbar, what is its height with respect to the crossbar when it reaches the plane of the crossbar?
In the 1950s, an experimental train that had a mass of 2.30 x 10^4 kg was powered across a level track by a jet engine that produced the thrust of 5.30 x 10^5 N for a distance of 504 m. unless otherwise directed, suppose that air resistance is neglig..
