Do neutrons have an electric charge

Neutrons have a neutral charge
Neutrons have no charge.

2001 toyoto blows fuse when you go in reverse

Not enough information. WHICH fuse blows out???

What is an example of electromagnetic

Which one of the following is not an example of and electromagnetic wave?

Is nickel attracted to a magnet

Yes yes it is............................................. because it has an ability to attacted the magnet

According to Coulomb's Law how does distance affect the electric force

Electric force can act at a distance, but is stronger when objects are closer.

the electric force is larger the closer the two objects are

The electric force varies with the distance between the charges. The closer they are, the stronger the force. The farther apart they are, the weaker the force.

How many electrons does a neutral atom with four protons contain
4 electrons
Charges repel each other

____________ charges repel each other.

like

What happens when two sound waves meet in destructive interference

The sound becomes softer or disappears.

When charging an object by conduction what happens to the charges in the object

Electrons move onto the object, giving it a static charge.

Apex ;)

Electromagnetic waves whose photons carry the highest energy also have what

Shortest wavelengths

What is a wave that requires a medium through which to travel

A mechanical wave such as a sound wave requires a medium to travel through.

Current is the movement of negative charges called protons

false

In a series circuit the is the same at every point

In a series circuit the current is the same at every point. This is Kirchoff's current law.

Do Electric field lines point from positive charges to negative charges

No not always. There could be from negative charges to positive charges.

!

After it passes how is the frequency you hear different from that being produced by the ambulance

It is lower due to the Doppler effect.

When a sounds intensity increases by a factor of 10 its decibel reading increases by dB

10

A 120 V power supply connected to a 30 ohm resistor will produce how many amps of current

A 120V power supply connected to a 30 Ohm resistor will produce 120/30 or 4 amps of current.

What has the lowest frequency on the electromagnetic spectrum

radio waves has lowest frequency in electromagnetic spectrum

What occurs to current in a circuit when voltage is increased

It increases

Why do radio waves travel faster than the sound wave

Radio waves are just low frequency light waves. They travel at the speed of light, much faster than sound waves which are just changes in pressure traveling in waves

Where are you most likely to build up enough static charge to receive shock

On a nylon carpet in a dry area.

Electrons are the smallest particle of an element that retains the original characteristics of the element

False
