Q. A 10.0-cm-high object is situated 25.0 cm in front of a convex mirror that has a radius of curvature of 1.00 102 cm.
(a) the location of the image is:The image is 16.7 cm in front of the mirror.The image is 16.7 cm behind the mirror. The image is 25.0 cm behind the mirror.The image is 25.0 cm in front of the mirror.
(b) the height of the image is:The image height is 8.67 cm.The image height is 10.0 cm. The image height is 7.67 cm.The image height is 6.67 cm.
A snowmobile climbs a hill at velocity v-up. The slope of the hill is a 2 ft rise for every 70 ft of distance. The resistive force of the snow is equal to 4.12 percent of the weight of the snowmobile. How fast will the snowmobile move downhill, assum..

A stream of water strikes a stationary turbine blade horizontally. The incident stream has a velocity of +16m/s whilst the exit has a velocity of -16m/s. mass of water per second that strikes the blade is 30kg/s.find the magnitude of average force ex..
Starting from rest, a 40 kg body reaches a speed of 8.0m/s in 2s. Calculate the force acting on the body?
A plate carries a charge of -3.9 µC, while a rod carries a charge of +2.2 µC. How many electrons should be transferred from the plate to the rod, so that both objects have the same charge.
Compute magnitude of the average velocity
A 105 granite cube slides down a 40 frictionless ramp. At the bottom, just as it exits onto a horizontal table, it collides with a 265 steel cube at rest. How high above the table must the granite cube be released to give the steel cube a speed of..
A 3.9 kg block originally at rest is pulled to the right along a horizontal, frictionless surface by a constant, horizontal force of 18 N.
Find the magnitude of the maximum force applied horizontally to upper block (block 1) that will cause the two blocks to slide together.
