Answer:
Explanation:
In a white T-shirt its is not as dark of a color as black so when the sun hits it you won't get hot as much or as quick. If you wear a back shirt you will most likely be hotter because since it is a darker color when the sun hits it it make you hotter and you heat up quicker. You still might feel hot in a white T-shirt because long sleeve shirts trap in your body heat making you hotter because the heat has nowhere else to go.
It can't. Acceleration IS a change in velocity.
The formula for the voltage is shown below:
Voltage = Current x Resistance
V=I x R
When we change voltage:
I =V/R or R=V/I
Increasing the voltage in an electrical circuit will also increase the current value, as well as the resistance of the load,
Q = m.s.Δt
Δt = Q /m.s
Here, Q = 30,000 J
m = 390 g
s = 3.9 J/g C
Substitute their values,
= 30,000 / 390 *3.9
= 30,000 / 1521
= -20 C (approx.) [-ve sign 'cause temperature is decreasing ]
In short, Your Answer would be Option D
Hope this helps!
