Answer:
And as we can see on the plot we have the distribution left skewed so then this distribution is not normal because we don't have a bell shaped histofram and is not symmetric.
Explanation:
Assuming the following dataset
Temperature (F) Frequency
50-54 2
55-59 0
60-64 4
65-69 12
70-74 7
75-79 5
80-84 1
For this case we can construct the histogram with the following R code.
f<-c(2,0,4,12,7,5,1)
> barplot(f)
And the result is on the figure attached.

Answer:
In summary, a photon is the tiniest possible particle of light, a quantum of light. A quantum, on the other hand, is the tiniest possible particle of any substance at the subatomic level and includes, for example, electrons and neutrinos.
A quantum is a packet of energy of definite magnitude, which may or may not be light energy. A photon is a packet of light energy having a difinite magnitude. Thus, a quantum may not be a phoyon but photon is a quantum.

Answer:
a) 3 * 10^9 ms
b) 1.6 * 10^-9 gm
c) 6.4 * 10^6 m
d) 5.48 * 10^5 s
Explanation:
Scientific notation is always written in [number from 0-10] (multiplied by) [10] raised to the power 'n'
Rate of change of momentum = impact force
(m*v-m*u)/t = F
4000*20/t = 80000 (note: v is zero as it stopped)
<span>soo, t = 1 sec</span>
