Wavelength and Frequency
Answer: 117.60N
Weight is a force. Therefore, we can use the force formula to find weight.
W = weight
m = mass
g = acceleration due to gravity ()
She applies 75N of force
F=ma
50=20(2.5)
F=30(2.5)
F=75 N
Answer:2.517 J/K
Given
Reservoir 1 Temperature
Reservoir 2 Temperature
Let Q is the amount of heat Flows i.e.
thus change in Entropy is given by
