Answer:
continue moving with constant velocity
Explanation:
Answer:
Correct answer : v = 50 m/s
Explanation:
The movement described is a free fall with no initial velocity and we will use the following formula:
v = g · t we take that g = 10 m/s²
v = 10 m/s²· 5 s = 50 m/s
v = 50 m/s

Answer:
(a). 2.8 minutes.
(b). 0.4732
Explanation:
Without mincing words, let's dive straight into the solution to the question.
So, for the part (a), the expected arrival time can be calculated as given below.
The distribution falls between the ranges of 0(lower boundary) to 5.5minutes(upper boundary).
Therefore, the expected time = (0 + 5.5)÷ 2 = 2.75 minutes = 2.8 minutes(to 2 decimal places).
(b). The probability that an elevator arrives in less than 2.6 minutes can be calculated as given below;
Recall: We have that the upper boundary = 0 and the lower boundary = 5.5 minutes for the distribution. Also, the upper limit is equal to 2.6 minutes and the lower limits = 0 minutes.
Therefore, 1/ (5.5 - 0) = 1/5.5 = 0.182.
Therefore, the probability that an elevator arrives in less than 2.6 minutes = 0.182 ( 2.6 - 0).
The probability that an elevator arrives in less than 2.6 minutes = ( 0.182 × 2.6).
The probability that an elevator arrives in less than 2.6 minutes = 0.4732.

Answer: I am pretty sure that you should pick radio waves.
Explanation: The scientist should use radio waves. I think this because you can use the radio waves to analyze the signals from outer space. This will work much better than anything there, to analyze it the best possible.
The best I could do.
