Momentum usually has the symbol p It is a vector, What is the correct way to write the symbol to show that it is a vector?

Many plants will grow from cuttings. The cutting develops a new root system and becomes a clone of the parent plant, but an independent new plant. This type of reproduction is called

Consider an electric dipole in a uniform electric field. In which orientation does the dipole-field system have the greatest potential energy?

You find a micrometer (a tool used to measure objects to the nearest 0.01 mm) that has been badly bent. How would it compare to a new, high-quality meterstick in terms of its precision? Its accuracy?

Sound with frequency 1300 Hz leaves a room through a doorway with a width of 1.03 m. At what minimum angle relative to the centerline perpendicular to the doorway will someone outside the room hear no sound

In static electricity what are the subatomic particles, their charges, their location in the atom

How does resistance affect the current in a circuit?

The period of a cepheid variable star and the time of one recent maximum can be used to predict the time of a future maximum. suppose that you calculate the time of future maximum brightness and then make measurements to observe this maximum.

An Ohmic material is one in which its resistance does not depend on the voltage across it or the current within it. In that case, the resistance does NOT depend on:

A concave lens is also called a diverging lens.
