Period of months where the weather is the coldest and the days are the shortest.
Answer:
Resistance in the flash tube, 
Explanation:
It is given that,
Speed of the bullet, v = 500 m/s
Distance between one RC constant, d = 1 mm = 0.001 m
Capacitance, 
The time constant of RC circuit is given by :

R is the resistance in the flash tube
..........(1)
Speed of the bullet is given by total distance divided by total time taken as :




Equation (1) becomes :


So, the resistance in the flash tube is
. Hence, this is the required solution.
It's 100% false, it wastes a ton (sorry for the bad pun!) of gas.
an ore is a naturally occurring solid material from which a metal or valuable mineral can be profitably extracted.
Specific heat capacity is the amount of energy required to raise the temperature of 1kg of a substance by 1 degree. Therefore, the higher the number, the more energy is required.
Hence, Steel will raise the most, since less energy is required to raise its temperature.
