A 1.56m tall student stands before a vertical mirror. She can just see her whole body, from head to toe.
Part A How tall is the mirror?
Part B If the student's eyes are 14cm below the top of her head, how far is the bottom of the mirror above the ground?
Calculate the capacitance of a planet, assuming it is a spherical capacitor of radius R = 9050.0 km with charge distributed throughout the volume of the sphere
A ferry boat transports tourists among three islands. It sails from the first island to the second island, 4.7 km away, in a direction 37.0° north of east. It then sails from the second island to the third island in a direction 69.0° west of north..
A golf ball is dropped from rest from a height of 8.30 m. It hits the pavement, then bounces back up, rising just 5.90 m before falling back down again, calculate the total amount of time that the ball is in the air
When a single person shouts at a football game, the sound intensity level at the center of the field is 59.9dB. When all the people shout together, the intensity level increases to 111dB.
Two, concentric, thin spherical shells of radii R1 = 31.3 cm and R2 = 39.1 cm are uniformly charged with a total charge Q1 = -56.5 ?C, What is the potential of the outer shell
Three resistors, 28, 48, and 80 ?, are connected in series, and a 0.53-A current passes through them. What is the potential difference across the three resistors
Police determine skid marks 83 m long on the highway showing where the car made an emergency stop. Assume that the acceleration was -10 m/s2 (about the highest for dry pavement), how fast was the car going.
