Answer:
Clouds
Explanation:
In an area, where the temperature is relatively high, then the warm air rises upward due to its less density. As these air rises upward, the air cools due to the decreasing temperature with the increasing height. There comes such a point where the air is not capable of holding any more water vapor, and it cools below the dew point. This process eventually leads to the formation of clouds in the sky, and with further cooling, the tiny droplets are formed, resulting in the occurrence of rain.
By convection radiation...the heat from the sun travels to the towel through air molecules(radiation),the heat is then transfer in the towel through water molecules(convection)..thereby gradually drying up the water molecules in the towel
Answer:
Minimum velocity is 25m/s
Explanation:
Given force F =1000N
Mass flow rate m/t= 40kg/s
Velocity=v
Recall Newton second law of motion F =MV/t
1000=40v
V=1000/40
25m/s
