Answer:
90 A
Explanation:
Applying,
P = VI.............. Equation 1
Where P = Power, V = Supply voltage, I = current.
Make I the subject of the equation
I = P/V.............. Equation 2
From the question,
Assuming the Voltage of the main electric supply is 120 V
Given: P = 10.8 kW = 10800 W, V = 120 V (household voltage)
Substitute these values into equation 2
I = 10800/120
I = 90 A
"1 Ampere" (A) means "1 coulomb of charge per second"
140 A means 140 coulombs per second
(140 coulomb/sec) x (0.9 sec) = 126 coulombs of charge.
Go a little farther:
Electrons are the things that move through wire carrying charge.
6.25 x 10¹⁸ electrons carry 1 coulomb of charge.
126 coulombs = 787,500,000,000,000,000,000 electrons (rounded)
Malleable basically means bendable and shapeable. notebook paper is the easiest to bend and shape
Answer:
I believe you are correct but we just started this unit
Explanation:
<span>Answer:
F=GMm/r^2 where G is the newtonian grav cst, M the mass of the star, m the mass of the planet, and r the planet-star distance
F1=GMm1/r1^2
F2=GMm2/r^2
F2/F1 = [GMm2/r2^2]/[GMm1/r1^2]
F2/F1=(m2/m1)(r1/r2)^2 = (2)(1/2)^2 = 1/2
because m2/m1=2 and r2/r1=2</span>
