Why are circuits important? Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different. Describe Ohm’s law and give an example of how Ohm’s law works. Define resistance and describe why resistance is important in a circuit.
Force of impact is the force ________________. A. of velocity B. of acceleration C. generated when objects meet D. of momentum
A 33 kg gun is standing on a frictionless surface. The gun fires a 57.7g bullet with a muzzle velocity of 325m/s. The positive direction is that of the bullet. Calculate the kinetic energy of thebullet immediately after the gun was fired. Answer in units of J
a ball is thrown with an initial velocity of 80 feet per second, at an angle of 40 degrees with the horizontal. Find the vertical and horizontal components of the velocity.
Two steel blocks rest on a frictionless, horizontal surface. Block X has a mass of 6.0 kg and is attached by means of a light taut string to block Y that has a mass of 12 kg. A force of 36 N [E] is applied to block X as shown below. Calculate the force block Y exerts on block X.
