Question 1 0/1 pts Africtionless cart is at rest on a tabletop and has a mass of 2.3 kg. It is tied by a massless string resting on a massless and frictionless pulley to a mass of 1.

When using a microscope, what position should the stage be in when you first start focusing on your specimen?

A slinky is stretched across a classroom to 9 meters. A compression travels along the slinky at a velocity of 2 m s. How long does it take the compression to travel the entire 9m length of the classroom?

An object is in circular motion with a constant speed of 4 m/s with a radius of 4 m. what is the centripetal acceleration of the object?

Potential energy and kinetic energy are created when work is done to change a position (PE) or a state of motion (KE). Ignoring friction, how does the amount of work done to make the change compare to the amount of PE or KE created? a.

The wavelength of a wave is the wavelength of a wave is how strong the wave is. equal to the speed of the wave times the wave's frequency. the distance between where the wave is emitted and where it is absorbed.
