Answer:
Option B: the period during which a solid is not changing state; its temperature is increasing
Explanation:
The temperature is defined as a measurement of the speed at which particles of matter are moving (their kinetic energy)
Therefore for an increase of kinetic energy to take place, and increase of temperature has to occur.
Answer:
45C in a minute is
45/60 C in a second
.75 C in a second is 3/4 of an ampere.
Explanation:
Answer:
The larger resistance value is 144 ohms and the smaller resistance value is 48 ohms.
Explanation:
Given that Resistance, R, is inversely proportional to Power, the largest value of power will yield the smallest value of resistance and vice versa.
The largest value of resistance will be:
P = V²/R
R = V²/P
R = 120²/100
R = 144 ohms
The smallest value of resistance will be:
R = 120²/300
R = 48 ohms
