Answer:
0.0014352 inch
Explanation:
= Coefficient of linear expansion of steel =
= Coefficient of linear expansion of copper =
= Original diameter = 8 in
= Change in temperature
Change in diameter of steel
Change in diameter of copper
Difference in diameter is given by
The difference in diameter change for the copper and the steel is 0.0014352 inch
Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that initially the grass hopper is at rest at the ground position
Now the acceleration is given as
distance of the legs that it stretched is given as
so we have
Part b)
time taken to reach this speed is given as
Part c)
as the grass hopper reach the maximum height its final speed would be zero
so we will have
I think the answer is Bell 4 may have either a positive or neg
-- Heat is a form of energy.
-- Joule is the SI unit of energy.
ergo
-- Joule is a unit of heat.
'Degree Celsius' and 'Kelvin' are units of temperature.
Heat and temperature are different things.
We won't go there right now.
