PLEASE HELP DUE TODAY A 65-kg male ice skater is facing a 45-kg female ice skater. They are at rest on the ice. They push off each other and move in opposite directions. The female skater moves backwards with a speed of 3 m/s. Determine the post-impulse speed of the male skater.

A 50-gram tennis ball is loaded into a 2-kg homemade cannon. The cannon is at rest when it is ignited. Immediately after the impulse of the explosion, a photogate timer measures the cannon to recoil backwards a distance of 6 cm in 0.02 seconds. Determine the post-explosion speed of the cannon and of the tennis ball (watch your units!!!)
Post-explosion speed of the cannon:
Post-explosion speed of the tennis ball:

Which simple machine is not part of this compound machine? a. lever b. pulley c. inclined plane d. wheel and axle

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Argon, neon, and xenon are examples of
