Each croquet ball in a set has a mass of 0.52 kg. The green ball, traveling at 13.1 m/s, strikes the blue ball, which is at rest. Assuming that the balls slide on a frictionless surface and all collisions are head-on, find the final speed of the blue ball in each of the following situations:
a) The green ball stops moving after it strikes the blue ball.
b) The green ball continues moving after the collision at 2.7 m/s in the same direction.
c) The green ball continues moving after the collision at 0.2 m/s in the same direction.
express what would be the frequency of vibrations.
What will be the speed if the string is replaced by one made of the same material and under the same tension however having twice the radius? (Answer in m/s)
A Carnot engine operating with an ideal gas takes heat energy from the hot reservoir at 500 degrees C and exhausts heat energy to the cold reservoir at 250 degrees C. If the engine does 400J of work per cycle, what is its efficiency.
You throw a 12-N stone vertically into the air from ground level. You observe that when it is 15.0 m above the ground, Find the stone's speed just as it left the ground
A recently developed method to study brain function is to produce arapidly changing magnetic field within the brain. When thistechnique, known as TMS, is applied to the prefrontal cortex, forexample, it can reduce a person's ability to conjugate v..
A 3.2- cm-radius 120-turn coil of 12.5 Ω resistance rotates about a diameter in a uniform magnetic field of 0.07 T. how much charge would it record when the coil is flipped
A 83-turn circular coil (radius = 37 cm) by a total resistance of 7.4 Ω is placed in a uniform magnetic field directed perpendicular to the plane of the coil. The magnitude of this field varies by time according to B = A sin (ωt), where the amplitude..
