A block slides across a rough, horizontal tabletop. As the block comes to rest, there is an increase in the block-tabletop system's (1) gravitational potential energy (2) elastic potential energy (3) kinetic energy (4) internal (thermal) energy

Drag a battery into the construction panel, and use the voltmeter to determine which end of the battery is the positive terminal.

What is true about the direction of the force of friction?

Which is true? An ideal emf device has internal resistance and a real emf device does not. A real emf device sets up a potential difference and an ideal emf device does not.

An object is released from rest on a planetthat has no atmosphere. The object fallsfreely for 2.03 m in the first second. What is the magnitude of the accelerationdue to gravity on the planet?

Two cards are drawn at random with replacement. Find P (not blue, then pink). (Remember, percent is a fraction with 100 in the denominator.)
