Block A with mass 3.72 kg travels with speed vi=3.74 m/s on a smooth horizontal surface and collides with a stationary block B whose mass is 2.29 kg. The blocks stick together when they collide. How much kinetic energy was lost in the collision?
Two positive point charges each have a charge of +q and are fixed on the y axis at y = +a and y = -a. (Use the following as necessary: k, q, a, and x.), Find the electric potential at any point on the x axis
A block of mass m=1.40 kg oscillates in simple harmonic motion due to the force of the spring to which the block is attached to. Express the displacement of the spring in terms of A when v= vm/2 and find its value
6 kg of an ideal gas is in a volume of 1 m3 at 250°C. The gas undergoes a constant pressure change of state until the temperature is 500°C. Find the pressure at the initial state
At what distance from the ring's center is E maximum. How deep is the tank.
Three small spheres, each have a charge of 3.60 %u03BCC, are arranged in a line, with sphere 2 in the middle. Adjacent spheres are initially 8.70 cm apart. What is the speed of each sphere when they are far apart
Attaching this non-ideal voltmeter decreases the voltage across R2. Calculate the magnitude of this decrease using an emf of 14 V and R1 = R2 = 350 k?
A 2.4-kg block is dropped from a height of 5.0 m onto a spring of spring constant 3955 N/m. When the block is momentarily at rest, the spring has compressed by 25 cm.
