Answer:
6.16717 m
Explanation:
m = Mass of person
g = Acceleration due to gravity = 9.81 m/s²
h = Vertical height
v = Velocity of person = 11 m/s
According to the question
The height the person would need to climb is 6.16717 m
Answer:
7 seconds
Explanation:
he went down -28 m/s so 7 times -4 equals -28 m/s which is what he needed to slowness down to 10 m/s
Answer:
A) Become 1/ 2 of its original value.
B) Become one-half of its original value.
Explanation:
As we know that heat transfer trough the wall of thickness t given as
Where
K=Thermal conductivity of the wall
A= Cross sectional area of the wall
t=Thickness of the wall
ΔT=temperature difference across the wall surfaces.
When the thickness become double ,lets sat t' = 2 t
Then new heat transfer
Therefore the new heat transfer become half of the original.
