Energy required = mass x specific heat x temperature difference
= 0.5 x 4.19x10^3 x 2
= 4190J
F = qE = mg
E = mg/q = 0.017*9.81('-3.1x10^-6) = 5.38x10^4 = -53,800 N/C
E' = 0.5E = -26,900N/C
2q -mg= ma, Answer is 9.81 m/s^2 and it's positive because the force is upward.
Ok, but where’s the question?
The answer for this question is, it was attempting to make the motor cycle safe
Assuming all three bulbs are connected properly with their conductivity creating a circuit, if one is unscrewed all bulbs would shut off causing zero emission of light to be displaced. Meaning answer D would be the closest to the right response.
Hope this helps! :)
