Answer:

Explanation:
From the question we are told that
Radius of vertical r= 8m
Force exerted by passengers is 1/4 of weight
Generally the net force acting on top of the roller coaster is give to be

where


Generally the net force is given to be 




Mathematical we can now derive V




Therefore the speed of the roller coaster is given ton be 
When rounding you look at the number right after the one you want to round. The tenth place is the one right after the decimal. If the number after it is more than five it goes up by one, it it's less than five it stays the same. So since the number after the 8 is a 3 it stays the same.
The answer is 7.8
Answer:
$25
Explanation:
The computation of the intrinsic value of the stock is shown below:
As we know that
Intrinsic value or Price = Dividend ÷ (Cost of equity - growth rate)
where,
Cost of equity or ke is
= Risk free rate of return + beta × (Market rate of return - risk free rate of return)
= 6% + 0.75 × (14% - 6%)
= 12 %
So the intrinsic value is
= $1.50 ÷ (12% - 6%)
= $25
Explanation:
It is given that,
Bandwidth of a laser source, 
(b) Let t is the time separation of sections of sections of the light wave that can still interfere. The time period is given by :



(a) Let h is the coherence length of the source. It is given by :

c is the speed of light

l = 0.0099 m
Hence, this is the required solution.
