Answer: Salt
Explanation: Alkenes, esters, and salts are all functional groups either containing or being functional groups.
Answer: Electrostatic force of attraction
Explanation: Electrostatic force of attraction is the force of attraction or repulsion between two electrically charged particles at rest. Like charges repel and unlike charges attract each other.
The formula (there is one) that determines the strength of an electromagnet is
H = I*N/L
H is the strength
I is the current
N is the number of turns
L is the length.
Question One
As N goes up, so does the strength of the electromagnet. The formula tells you this. If he wants a stronger magnet, he must <em>Increase </em>the number of turns.
The resistance of the wire will likely stay the same when you don't add any more turns. So if you increase the voltage, you will increase the current. That means you get a stronger magnet.
Power is the rate of work or energy. It has units of Watts. For an electrical circuit, it can be calculated by multiplying the voltage and the current flowing. Ampere represents the amount of electricity while voltage represents the force of the electricity flowing. We calculate as follows:
P = IV
P = 1 A (5x10^2 V)
P = 5x10^2 W
