Q. A rabbit runs in a straight line with a velocity of +1.40 m/s for a period of time, rests for 12 s, and then runs again along the same line at +0.63 m/s for an unknown amount of time. The rabbit travels a total distance of 1092m, and its average speed is 0.730 m/s. How long did the rabbit run for 1.40 m/s and how long did it run for 0.63 m/s?
Q. Imagine adding electrons to the to the pin until the negative charge has the very large value 1 mC. How many electrons are added for every electron before now present?
The two blocks are on frictionless inclines and are in static equilibrium. The block on the left has a mass of 49 Kg, and the block on the right has a mass of n3 Kg. If the left incline has the length of n1 meters, and the right incline the length of..
What could you expect the intrusion into the vechicle is, based on this information? Explain how you arrived at this intrusion.
The distance between a loudspeaker and the left ear of a listener is 1.60 m. compute the time required for sound to travel this distance if the air temperature is 20° C.
A rocket is launched at an angle of 57.0° above the horizontal with an initial speed of 99 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 30.0 m/s2. At this time, its engines fail and the rocket proceeds ..
A broad beam of light of wavelength 642 nm is incident at 90° on a thin, wedge-shaped film with the index of refraction 1.50. An observer intercepting light transmitted by the film sees 17 bright and 16 dark fringes along the length of the film. B..
A car is driven 155 km west and then 75 km southwest. What is the displacement of the car from the point of origin (magnitude and direction).
the magnitude of the net electric field. A lead ball is dropped into a lake from a diving board 6.40 above the water. After entering the water, it sinks to the bottom with a constant velocity equal to the velocity with which it hit the water.
Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles q1, q2 and q3 respectively and free. The approximation sin q = q holds for all three angles, with q3 > q2 > q1. How do the angular frequencies of th..
