A60kg block is at rest on a ramp inclined at 35 degrees.

a) draw a fbd. label normal, gravitational, and frictional force.
b) determine the magnitude of the force of friction acting on the block
c) determine the magnitude of the normal force acting on the block
d) determine the coefficient of friction between the block and the ramp.

List one type of erosion and describe how it happens?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

Which are advantages of renewable resources? check all that apply. renewable energy supplies are completely reliable everywhere. some renewable resources will never be used up. little or no waste is produced by renewable resource plants. electricity can be generated in large quantities. many renewable energy facilities have lower operating costs.
