C. permanent positive charges
Answer:
Explanation:
Given
Velocity = 388m/s
Height S = 2.89m
Required
Time
Using the equation of motion
S =ut+1/2gt²
2.89 = 388t+1/2(9.8)t²
2.89 = 388t+4.9t²
Rearrange
4.9t²+388t-2.89 =0
Factorize
t = -388±√388²-4(4.9)(2.89)/2(4.9)
t= -388±√(388²-56.644)/9.8
t = -388±387.93/9.8
t =0.073/9.8
t = 0.00744 seconds
Remember the following formulas to convert temperatures between Farenheit and Celsius:

Convert all the temperatures to Celsius to compare them.
<h2>
Part a)</h2>
Convert 265ºF to Celsius:

Then, 265ºF is equal to 129.444...ºC. Then, 265ºC is higher than 265ºF.
The correct choice is option 2) 265ºC.
Part b)
Convert 370ºF to Celsius:

Then, 370ºF is equal to 187.777...ºC. Then, 200ºC is higher than 370ºF.
The correct choice is option 2) 200ºC.
