Which in is it Speed (S) or Velocity (V)?

Physics
1 answer:
Andrej [43]3 years ago
8 0

Explanation:

Speed has only magnitude.

Velocity has magnitude and direction.

"A bike goes 25 m/s toward  main street."

This includes a direction, so it is velocity (V).

"A person walks 4 mph."

This has only magnitude, so it is speed (S).

"A plane flies 200 m/s."

This has only magnitude, so it is speed (S).

"A bird flies 100 mph due south."

This includes a direction, so it is velocity (V).

2. Determine the current in a 120-watt bulb plugged into a 120-volt outlet.
Sergio039 [100]

Answer:

1 ampere

Explanation:

Power = VI

V = voltage

I = current

Given

Power = 120 watts

V = 120 volts

Therefore

120 = 120 x I

Divide both sides by 120

120/120 = 120/120 x I

1 = I

I = 1 ampere

what is the relationship between the number of turns of the wire and electrical output of the generator?
xxTIMURxx [149]

The number of turns of wire is directly proportional to voltage.

The higher the number of turns of wire the higher the voltage

Since .

Power (output) of a generator = voltage x current. Therefore the higher the voltage the higher the output of the generator.

So, the higher the number of turns of wire the higher the output of the generator.
