Answer:An object that absorbs ALL radiation falling on it, at all wavelengths, is called a blackbody. When a blackbody is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. ... As its temperature increases further it becomes yellow, white, and ultimately blue-white
Explanation:
The energy required to start a reaction IS called the activation energy. TRUE
The answer is D. The input force is equal to the output force.
I just did test and got it right
Answer:
c. V = k Q1 * Q2 / R1 potential energy of Q1 and Q2 separated by R
V2 / V1 = (R1 / R2) = 1/4
V2 = V1 / 4
If the metal plate that has a circular hole with radius R. And if we raise the temperature of this plate the radius of the hole will increase.
