Answer:
A) Electrons only
Explanation:
In quantum mechanics, "electron cloud" refers to the region of space where electrons can be found in an atom. In fact, in quantum mechanics, it is not possible to predict the exact position of the electrons, so there is a region where electrons have a certain probability to be found.
The wavelength of a wave varies inversely as its frequency, i.e.
W ∝ 1/F
A wave decreases its frequency from 600kHz to 300kHz, so let's calculate the scaling factor of W due to the change in F.
k = 1/(300/600) = 2
To find the new wavelength, multiply the original wavelength by k:
W = 2×129m
W = 258m
Answer:
a. Fr^2 = 119.7^2 + 49.9^2 = 16,818.1
Fr = 129.7 N.
b. tanA = Y/X = 49.9/119.7 = 0.41688
A = 22.63o = Direction.
Explanation:
Answer:
Explanation:
We are going to use the accelerated motion formula 
on the vertical component taking the upwards direction as positive.
Since <em>at maximum height the speed will be 
</em>, the formula can be written as 
, which for our values is:
Written to three decimal places.
