1. Calculate the resistance of a 12v, 20-amp circuit.

Physics
1 answer:
Elis [28]3 years ago
7 0

Answer:

R = 0.6 ohms

Explanation:

We have,

Voltage of the circuit is 12 V

Current flowing in the circuit is 20 A

It is required to find the resistance of the circuit. Ohm'slaw gives the relationship between voltage, current and resistance. It is given by :

V=IR

R = resistance

R=\dfrac{V}{I}\\\\R=\dfrac{12}{20}\\\\R=0.6\ \Omega

so, the resistance of the circuit is 0.6 ohms.

The sound from a bolt of lightning travelled 4.08 km in 12.0 s. What was the speed
LenaWriter [7]

Answer:

83.67 m/s

Explanation:

Set up a calculation to convert units of measure to what you need.

You have km/s and you need m/s.

4.08km     1000 m         83.67m

-----------  X ----------  =  ---------------   the km will cancel out and you are left

 12.0 s          1 km              s              with m/s

a brick is suspended above the ground at a height of 6.6 m. it has a mass of 5.3 kg. what is the potential energy of the brick
Svetradugi [14.3K]
The formula for potential energy is
E(p) = mgh

(Mass x gravity x height)

Therefore energy = (5.3)(9.8)(6.6)
= 342.8 J

How did I get 9.8?
9.8 is the constant for gravity
