An electric iron consumes energy at a rate of 840 W when heating is at the maximum rate and 360 W when the heating is at the minimum. The voltage is 220 V. What are the current and the resistance in each case?
Don't spam
Answer:
At maximum the current is 4A and resistance is 55Ω
At minimum the current is 1.636A and resistance is 134.45Ω
Explanation:
The computation of the current and the resistance in each case is shown below:
At the time when it is heated at max rate,
power, P = 840W
V = 220V
As We know that
P = VI
840 = 220 × I
I = 840 ÷ 220
I = 4 A
Now
R = V ÷ I
= 220 ÷4
= 55 Ω
Hence, the current is 4A and resistance is 55Ω
At the time When it is heated at minimum rate,
power, P = 360W
V = 220V
As We know that
P = VI
360 = 220 × I
I = 360 ÷ 220
I = 1.636 A
Now
R = V÷ I
= 220 ÷1.636
= 134.45 Ω
Hence, the current is 1.636A and resistance is 134.45Ω
the moon doesn't fall to earth because of it's friction?
Answer:
The Moon does not fall towards Earth right now because Earth rotates itself. The energy from the Earth's own rotation around its axis is gradually tranferred into energy of the Moon's orbital motion. That's why the Earth's rotating speed decreases but the distance to the Moon increases.
Answer:
I think No since the gravitational force of earth is not eneogh to pull moon to it
in prokaryotic and eukaryotic cells the amount of water in the cell is kept at a steady state. The organelles
through which water passes into and out of cell is the
A) cell membrane
B) cell wall
C) nuclear
D) ribosome
Answer:
A
Explanation:
It would not be C because prokaryotic cells don't have a nucleus. And if you're looking for a body in the cell that controls the nutrients and water it would be A.

Answer #1:
Physical.
Explanation:
The only thing mentioned to change is the color. Nothing about the gas in general is changing
Answer #2:
Chemical.
Explanation:
The fact this interacted with another element to completely turn something else rather than just being that color makes this a chemical change.
Answer #3:
Physical
Explanation:
Well, how does an element's density have to do anything with a chemical change?
Answer #4:
Chemical.
Explanation:
Fire/heat is involved, and it makes it change states.
How fast must a person lift a barbell with a weight of 635 N to a height of 2.43 meters in order to have a power of 482 W
Answer:
Time = 3.2 seconds
Explanation:
Given the following data;
Weight = 635 N
Height, h = 2.43 m
Power = 482 Watts
To find the time;
Power = mgh/time
But weight = mg = 635
Substituting into the formula, we have;
482 = (635 * 2.43)/time
482 = 1543.05/time
Time = 1543.05/482
Time = 3.2 seconds
