When the temperature lowers the plants can freeze and die. One way to prevent that is to cover the plants so they dont freeze
To be honest, the picture is so far above that I can't see it at all.
But reading the information in the question's statement, I'd say
the blank should be filled in so that it says:
<span> The chemical energy in the battery is used to light up the light bulb
on the other end. Chemical energy in the battery is transformed into
electrical energy which runs through the circuit wire. (A)</span>
The Correct choice is ~
D. 18.0 Newtons
because the resultant force can't exceed 16 Newtons ~
Using the equation:
Energy transferred = Charge x Potential difference
Rearrange for p.d:
V = E/Q
Substitute values:
V = 80/20
V = 4
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.
