Clothes in a dryer acquire static cling by
The loss of static electricity as electric charges move off an object is called
A student is investigating the properties of Block A. The student writes down the following notes as they investigate:
1. Placed Block A on top of a hot metal block and then touched Block A with finger.
2. Held finger on Block A for five minutes, but Block A is still only room temperature.
How do electrically charged objects affect neutral objects when they come in contact?
This diagram shows a negatively charged balloon. When the charged balloon is brought near some pieces of paper, the papers are attracted to the balloon.
A balloon has a negative charge. A glass rod has a positive charge.
What will happen when the glass rod is brought near the balloon?
Thunder clouds carry a vast amount of negative charges near the bottom and an equal amount of corresponding positive charges near the top. When the clouds build up over us in the sky, these charges accumulate at sharper points. Then, suddenly a massive electric flow takes place between such a point and the cloud in question. This is called a lightning strike or thunderbolt. Which of the following statements it most accurate.
An electrician wraps rubber electrical tape around a copper wire. Since rubber is an insulator, which statement BEST explains the point of wrapping rubber around a copper wire?
Suppose you acquire a positive charge from walking across a carpet. You then touch a doorknob and receive a shock. This leaves you
How does alternating current differ from direct current?
The table lists the current and number of turns in the wire for four electromagnets.
Which electromagnet will generate the strongest magnetic force?
An electromagnet is a kind of permanent magnet.
The material of the coil does not affect the strength of an electromagnet.
The poles of an electromagnet can even be reversed by reversing the flow of electricity.
Match the term to the correct definition.
Match the term to the correct definition.
What states that charges cannot be created or destroyed?
An electromagnet can be made stronger by ______ the number of turns on a coil and ______ the current flowing in the wire.
