A child slides down a slide with a 24° incline, and at the bottom her speed is precisely three-fifths what it would have been if the slide had been frictionless. calculate the coefficient of kinetic friction between the slide and the child.

How much heat energy must be removed from 100 g of oxygen at 22°C to liquefy it at - 183°C? (The specific heat of oxygen gas is 0.218 cal/g⋅°C, and its heat of vaporization is 50.9 cal/g.) a. 13 700 calb. 9 560 calc. 4 320 cald. 2 160 cal

The minimum amount of energy that can be absorbed or released by matter is called

A circuit consists of a 12.0-V battery connected to three resistors (44ohm, 17ohm and 110ohm) in series. a. Find the current that flows through the battery. I=__mAb. Find the potential difference across the 44ohm resistor. V1=__Vc.

A ball is moving at a speed of 5 mi/h along a frictionless surface. It will continue moving at this speed as long as (Select all that apply) A) something keeps pushing it because it requires a force to continue its motion B) balanced forces act up

Sort the tiles into the appropriate categories.

My Notes A basketball rolls across a classroom floor without slipping, with its center of mass moving at a certain speed. A block of ice of the same mass is set sliding across the floor with the same speed along a parallel line.

How does sound travel through waves?

Solve for real t: - 25=20t-5t^2

Contrast balanced and unbalanced forces.

A wave will travel only as long as it has energy
