Describe, using a clear, complete sentence, how the motion of object 2 differs from the motion of object 1. Explain how you know.
A typical power plant uses some fuel as the source of heat (QH) to drive a heat engine that does work (W) to drive a generator that is connected to the electrical grid. Inevitably, waste heat (QC) is dumped into a river or lake. Analysis of the pl..
A ball is thrown upward in the air by a passengeron a train that is moving with constant velocity. Describe the path of the ball as seen by the passenger
Two thin converging lenses are placed on a common axis, so that the center of one of them coincides with the focus of the other.
A 600 gram particle (initially at rest at the origin) is subjected to a force of F=15i+20j (N) which pushes the particle along a track with a displacement described by s=3i+4j (m). calculate the average power produced by this force
What is the longest wavelength of light capable of ionizing a hydrogen atom in the n = 2 state
A particle with a mass of 2.0×105kg and a charge of +2.9C is released in a (parallel plate) uniform horizontal electric field of 15N/C. How far horizontally does the particle travel in 0.40s? What is the horizontal component of its velocity at that p..
An outside loudspeaker (considered a small source) emits soundwaves with a power output of 75 W. Find the intensity level in decibels at that distance.
a 800kg car pushes a 1900kg truck that has a dead battery. when the driver steps on the accelerator the drive wheels
Starting from a location with position vector r1,x = -16.5 m and r1,y = 22.7 m, a rabbit hops around for 11.3 seconds with average velocity vav,x =-2.27 m/s and vav,y = 1.47 m/s. Find the components of the position vector
A rotating fan completes 1200 revolutions every minute. Consider a point on the tip of a blade, at a radius of 0.13 meter. Find through what distance does the point move in one revolution
What was an initial speed of the ball
A block with mass m has a coefficient of kinetic friction Mk with the floor. If the block is obeying Newton's 1st law while being pushed at angle 0 (theta), show that the power needed to push it at velocity v is given by P=Mkv(mg+fsin0)
