Putting effort at point IV of this lever gives no mechanical advantage because it <em>requires a greater force.</em> So the correct answer is <em>C)</em>.
Answer:

Explanation:
Given
Density = 3 starts in 10 cubic light years.
Required
Determine the probability of 1 or more in 10 cubic light years
Since the number of stars follow a Poisson distribution, we make use of:




T = the light years

Calculating 
In probability:

Calculating P(X=0)
Substitute 0 for k and the values for
and T in








Substitute 0.04979 for P(X=0) in 


--- approximated
<em>Hence, the required probability is 0.9502</em>
Recall that

We're given
,
(so we take the upward direction to be positive), and
. Then the final velocity
satisfies
