Answer:
I believe its Gas to Solid :)
Explanation:
Since it travels at 21,000 kilometers per hour, you'd just multiply that with 3.5 to get 73,500. So your answer is 73,500.
Here we can say that rate of flow must be constant
so here we will have
now we know that
now from above equation
so velocity will reduce by factor 0.14
Answer:
0.0757 kg
Explanation:
m = mass of the body = 95 kg = 95000 g
ΔT = change in the temperature of the body = 0.45 °C
c = specific heat capacity of the body = 4.0 J/(g °C)
M = mass of water evaporated
L = latent heat of vaporization of water = 2260 J/g
Using conservation of heat
Heat gained by water = heat lost by body
ML = m c ΔT
M (2260) = (95000) (4.0) (0.45)
M = 75.7 g
M = 0.0757 kg
Answer:
Work cause a change in kinetic energy
