True because it have a lot of energy at the top because of gravity and air restrictsence
Answer:
The probability is 0.2212
Solution:
As per the question:
Poisson rate, 
Now,
Let
X: time of waiting for the next vehicle on the highway
Now,
To find the probability of the next vehicle to arrive after 10 s
The probability distribution function is given by:

Now,
P(X < x) = 

For X> 0,
P(X > x) = 
P(X < 5) = 
Answer:
0.045 J
Explanation:
The work done on a charge moving through a potential difference is given by

where
W is the work done
q is the charge
is the potential difference
In this problem, we have
q = 0.0050 C is the charge
is the potential difference
Using the formula, we find the work done:

She does 200J .
We know she uses 20N of force and 10m is the distance. We multiply both numbers and we are given our answer of 200J. Hope this was helpful. :)
