Explanation:
Kinetic energy is the energy of a object in motion
Answer:
The time required to melt the frost is 3.25 hours.
Explanation:
The time required to melt the frost dependes on the latent heat of the frost and the amount of heat it is transfered by convection to the air .
The heat transferred per unit area can be expressed as:
being hc the convective heat transfer coefficient (2 Wm^-2K^-1) and ΔT the difference of temperature (20-0=20 °C or K).
If we take 1 m^2 of ice, with 2 mm of thickness, we have this volume
The mass of the frost can be estimated as
Then, the amount of heat needed to melt this surface (1 m²) of frost is
The time needed to melt the frost can be calculated as
During a nuclear reaction, fuel rods generate a tremendous amount of heat. ... Problems cooling these pools have officials worried that the spent rods could ... appear to be related to one or more of the spent fuel storage pools at the plant. ... These fission byproducts are also very radioactive.
does that kind of help a little?
Answer: A when going down the periodic table your atomic radius will get bigger same if you got to the side. B Moving left to right within a period or upward within a group, the first ionization energy generally increases
Explanation:
Answer:
1/2hour
Explanation:
it takes the runner 1 hour to complete 10km
so 5km is half of 10km therefore would take half the time
hope that helps:)
