1. calculate how many electrons you need to get a charge of 1 coulomb.

2. calculate the charge that flows through the cross-section of a wire in 60 seconds at a current of 100ma. how many electrons are needed to get that charge?

3. there is an electrical voltage of 5 volts between two points. what does that mean? use the words work and energy in your explanation.

4. right or wrong?
- voltage is the consequence and current is the cause
- a battery and a socket are both voltage sources.
- an electric current can only flow in a closed circuit.

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

snell's law

refractve index = sin incidence / sin refraction
