C- escape into the solar system, because the sun is neither a solid nor a liquid, and the sun already creates its warm temperature from many reactions. the light from the sun can scatter throughout the universe, eventually getting to earth. do, have you ever heard of a wave of light being referred to as a solid or a liquid?
Answer:
162.8 K
Explanation:
initial current = io
final current, i = io/8
Let the potential difference is V.
coefficient of resistivity, α = 43 x 10^-3 /K
Let the resistance is R and the final resistance is Ro.
The resistance varies with temperature
R = Ro ( 1 + α ΔT)
V/i = V/io (1 + α ΔT )
8 = 1 + 43 x 10^-3 x ΔT
7 = 43 x 10^-3 x ΔT
ΔT = 162.8 K
Thus, the rise in temperature is 162.8 K.
The kinetic energy (KE) is 250 J and the gravitational potential energy (GPE) is 392 J
Answer:
D,B,C,A,C
Explanation:
I believe that is the correct answers but it is unclear. I don't think the key for the second last question would let the current flowing so the bulb would be off.
If two object experiences the same displacement at the same time, the two objects must have the same average velocity.
The average velocity of an object is defined as the change in displacement per change in time of motion. This can be written as follows;
If two object experiences the same displacement at the same time, it means that the change in displacement with time is constant.
Thus, we can conclude that if two object experiences the same displacement at the same time, the two objects must have the same average velocity.
