Answer:
Radiation
Explanation:
The heat transfer take place by three modes
1. Conduction
This type of heat transfer take place in the solid materials like metals .This heat transfer take place due to vibration of electron.
2.Convection
This type of heat transfer take place in the moving fluid like water ,air etc.
3.Radiation
Every materials which having temperature above 0 K are emitting radiation.This type of heat transfer dominate at the high temperature.
We know that temperature of sun is so high so the heat transfer from sun to the earth is take place by radiation mainly.
Answer: True
Explanation: Hope this helps :)
Use the formular d = v x t
d = 2m
v= 100m/s
t= d / v
= 2 / 100
= 0.02sec
Answer:
s = 23.72 m
v = 21.56 m/s²
Explanation:
given
time to reach the ground (t) = 2.2 second
we know that
a) s = u t + 0.5 g t²
u = 0 m/s
g = 9.8 m/s²
s = 0 + 0.5 × 9.8 × 2.2²
s = 23.72 m
b) impact velocity
v = √(2gh)
v = √(2× 9.8 × 23.72)
v = √464.912
v = 21.56 m/s²
