Answer: a boy jumping down
Answer:
502000W/m²
Heat flux = 800×50.2/20 =
502000W/m²
Explanation:
Explanation:
solution: mass m = 5g = 0.005kg; extension e = 7cm = 0.07m; force f = 70 N; velocity = ?; using: work done in elastic material w = 1/2 fe = 1/2 ke2 = 1/2 mv2 - the kinetic energy of the moving stone. 1/2 fe =...
Answer:
The change in length is 0.01056 m.
Explanation:
Given that,
Length = 11 m
Temperature = 20°C
Pressure = 1 atm
Boiling temperature = 100°C
We need to calculate the length
Using formula of change in linear expansion


Put the value into the formula



Hence, The change in length is 0.01056 m.
