Answer:
it is an upside-down image but the brain realizes it and corrects it in its orientation so we see it in right direction.
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.
We can salve the problem by using the formula:
where F is the force applied, k is the spring constant and x is the stretching of the spring.
From the first situation we can calculate the spring constant, which is given by the ratio between the force applied and the stretching of the spring:
By using the value of the spring constant we calculated in the first step, we can calculate the new stretching of the spring when a force of 33 N is applied:
Answer:
The answer is A
Explanation:
Argon is the stable element that is used to determine the age of volcanic rock as it is found inside of it.
I dont know if the top is correct but the answer is because i just took the test.
I think the stream with the steep slope but i'm not entirely sure.
