The structure and curvature of the Earth results in beams of sunlight glancing off the equator and reaching other areas of the Earth. This means that the areas at the equator receive more energy as sun's rays hit them directly.
Therefore, the answer is C.
Answer:
The answer is 80 Joules
Explanation:
Electrical energy = Q x V
Energy = 2 x 40
= 80
I just took the test and it was right :D
The correct answer is B.
I hope this helped! :D
If the length and linear density are constant, the frequency is directly proportional to the square root of the tension.
Answer:
C has 5 electrons
Explanation:
Given:
The data acquired from the experiment performed by Millikan:
Q_a = 3.20 x10^{-19} C
Q_b = 4.80 x10^{-19} C
Q_c = 8.00 x 10^{-19} C
Q_d = 9.60 x 10^{-19} C
Find:
How many Electrons were present in drop C
Solution:
It is known that the charge of an electron e = 1.602 *10^-19 C / electron.
Hence the number of electrons n in drop C will be:
n = Q_c / e
n = 8.00 x 10^{-19} / 1.602*10^-19
n = 4.99 = 5 electrons
Answer: The drop C contains 5 electrons.
