The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT. Values of specific heat are dependent on the properties and phase of a given substance.
Explanation:
KE is directly proportional to the square of velocity / speed.
if speed is 2 times (doubled) the KE will be
= 4 times the original KE
Answer:
F = 1908 N
Explanation:
GIVEN,
Incident water stream has a velocity = U = +18.0 m/s,
Exiting water stream has a velocity = V = -18.0 m/s.
Mass of water per sec : M / t = 53 kg /s
Change in velocity d v =18 m / s – ( -18 m / s)
= 36 m / s
Magnitude of the average force exerted on the water by the blade
F = ( M / t ) x dv
=( 53 kg /s ) x ( 36 m/s )
F = 1908 N
