If the resistance remains constant and the voltage doubles, what effect will that have on the power?

Physics
1 answer:
aalyn [17]3 years ago
6 0
One of the handy formulas for electrical power is

Power = (Voltage)² / (Resistance)

Since the voltage is squared, if you double the voltage and
the resistance doesn't change, the power will increase by
the factor of (2²), which is 4 times the original power.

Guillaume Amontons first took a stab at measuring absolute zero in 1702. What would be the most reasonable way it would have bee
Oliga [24]

He would measure the speed of molecules as the temperature gets colder until the temperature is measured at which motion stops.

<h3>What is the absolute zero?</h3>

The absolute zero refers to the temperature at which the gas seems to stop moving. Recall that temperature is the measure of the average kinetic energy of the molecules of a gas.

Hence, if Guillaume Amontons first took a stab at measuring absolute zero in 1702, he would measure the speed of molecules as the temperature gets colder until the temperature is measured at which motion stops.

Which value represents accuracy: the mean, median, mode, range from center, or distance between farthest beanbags?
Olin [163]

Answer:

the mean

Explanation:

The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30. The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.

A 9Ω resistance is cut into three equal parts and connected in parallel. Find the equivalent resistance of the combination.​
sammy [17]

Answer:

the ans i 1 ohm

Explanation:

if i cut a resistor of 9 ohm into 3 equal parts then each resistor will have a resistance of 3 ohm and if they are in parallel combination the net resistance will be R

so 1/R=1/R1+1/R2+1/R3

     1/R=1/3+1/3+1/3

      R=1

Johnathan wants to lift a 200N box onto a 5m ledge. How much work is done?
Y_Kistochka [10]

Answer:

1000 J which agrees with answer a in your list of options

Explanation:

Recall the formula for work (W) as the force (F) applied times the distance (d) covered in the same direction of the force:

W = F * d

W = 200 N * 5 m = 1000 J
