Answer: The derivative of a constant term is always 0. So the acceleration of the body would be zero. Hence, the acceleration of a body moving with uniform velocity will always be zero.
Hope this helps :) :)
Answer:
A positive acceleration means and increase
A negative acceleration is a decrease
a zero acceleration is a constant movement so its not increasing or decreasing just constant
Explanation:
He has to use a different colored light at a higher frequency.
Answer:
Kinetic energy decreases as temperature decreases.
Explanation:
From the description that the system at 80°C has longer arrows, or move faster than the system at 20°C, having shorter actors indicating a slower motion, we can conclude that the kinetic energy of a body depends on its temperature.
If the system at 80°C shows a greater kinetic energy (faster motion of particles) than the system at 20°C, it then implies that decreasing the temperature of the body decreases its kinetic energy.
