A 100 kg box is loaded into the truck of a car. If the height of the cars bumper decreased by 20 cm, what is the force constant of its rear suspension?

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
