What particles contribute to the net charge

What substances will go to the core of a planet after it undergoes differentiation?

Why does the hood of a car heat up after the car has been running for a while? A) According to the fourth law of thermodynamics, the temperature of the other parts of the car increases due to the coolant used for the engine.

What is the momentum of a 91 - kilogram ice skater gliding across the ice at a speed of 9 m/s

Two blocks connected by a rope of negligible mass are being dragged by a force at a 22° angle above horizontal (see figure below). Suppose F = 89.0 N, m1 = 14.0 kg, m2 = 22.

Freight trains can produce only relatively small acceleration and decelerations. (a) what is the final velocity (in m/s) of a freight train that accelerates at a rate of 0.0600 m/s2 for 8.00 min, starting with an initial velocity of 5.00 m/s?

A D note has a frequency of 587.33 Hz. Calculate its wavelength in meters. The speed of sound is 343 m/s

A cyclist allows his bike to roll down a hill without pedaling. Towards the bottom of the hill he applies his brakes. The bike comes to a stop. Applying the brakes causes the brakes to warm up. Describe the energy transfers that have occurred.

An object is placed in a fluid and then released. Assume that the object either floats to the surface (settling so that the object is partly above and partly below the fluid surface) or sinks to the bottom.

Explain why it is important to have strong core muscles?

Potential energy is the energy an object has because of its A. density. B. size. C. location. D. speed. E. temperature.
