Answer: Scientist don't know where energy comes from and how it was created but God created energy.
Explanation:
Answer:
Explanation:
mass of coffee filter, m = 1.4 h
height, h = 4 m
velocity, v = 0.5 m/s
The energy conservation
Potential energy of filter = kinetic energy of filter + energy gained by the air molecules
m x g x h = 0.5 x mv² + energy gained by the air molecules
0.0014 x 9.8 x 4 = 0.5 x 0.0014 x 0.5 x 0.5 + Energy gained by the air molecules
Energy gained by the air molecules = 0.05488 - 0.00000175
= 0.054878 J
Answer:
When the machine indicates a lie, what is the probability that the suspect is really lying? If the machine does not indicate a lie, what is the probability that the suspect is really telling the truth?
My solution if the probability that a test subject is chosen at random from the 200 in fact lie = 80/(80+5)=0.94
Then when 15% of people arrested lie, the probability that the suspect is really lying is 0.15*0.94=0.141
Answer:L=109.16 m
Explanation:
Given
initial temperature
Final Temperature
mass flow rate of cold fluid
Initial Geothermal water temperature
Let final Temperature be T
mass flow rate of geothermal water
diameter of inner wall
specific heat of water
balancing energy
Heat lost by hot fluid=heat gained by cold Fluid
As heat exchanger is counter flow therefore
heat lost or gain by Fluid is equal to heat transfer in the heat exchanger
