Answer:
2.08V/cm
Explanation:
Plot the points on a graph. Draw the line of best fit. Calculate the gradietn of line of best fit.
Attached is the graph plotted on excel.
The equation of the line is
Votlage= 2.08× distance + 0.276
Uh, I’d assume so because Brainly has a whole section of questions for them.
It would be 72cm bc u need to add up all the line in the back to
Answer:
Geothermal energy.
Explanation:
Geothermal energy is called a renewable energy source because the water is replenished by rainfall, and the heat is continuously produced by the earth.
Answer:
18.75in
Explanation:
Modulus of elasticity = Stress/Strain
Since stress = Force/Area
Given
Force = 1000lb
Area = 0.75sqin
Stress = 1000/0.75
Stress = 1333.33lbsqin
Strain
Strain = Stress/Modulus of elasticity
Strain = 1333.33/5,000,000
Strain = 0.0002667
Also
Strain = extension/original length
extension = 0.005in
Original length = extension/strain
Original length = 0.005/0.0002667
Original length = 18.75in
Hence the original length of the rectangular bar is 18.75in
