Answer:
a.
Explanation:
a. Find the probability that exactly one photo detector of a pair is acceptable:
Let photo is accepted and the probability
is defected.
Therefore:
#The probability of exactly one photo detector of a pair is accepted is 7/25
b.Find the probability that both photo detectors in a pair are defective,P(D1D2):
Hence, from out tree diagram,the probability that both photo detectors in a pair are defective is 6/25
Answer:
It increased by a factor of 3.
Explanation:
The gravitational potential energy of an object is given by
where
m is the mass
g is the gravitational acceleration
h is the heigth of the object relative to some reference point (for instance, the ground)
As we see from the formula, the gravitational potential energy is directly proportional to the mass, m: therefore, if the mass of the cylinder is increased by a factor 3, then the gravitational potential energy will also increase by a factor 3.
