Answer:
240 ft
Explanation:
t = Time taken
u = Initial velocity = 96 ft/s
v = Final velocity
s = Displacement
a = Acceleration = 12 m/s² on Mars 32 ft/s² on Earth negative due to upward direction
Mars

Earth

Differentiating the first equation with respect to time we get

Equating with zero

Differentiating the second equation with respect to time we get
Equating with zero

Applying the time taken to the above equations, we get


Difference in height = 384-144 = 240 ft
The stone will travel 240 ft higher on Mars
Answer:
They both produce heat energy.
Answer: The lower areas of the Atmosphere have a high temperature through the heats from the ground.
Explanation: High temperature experienced on the Earth surface is majorly caused by heats from the ground ( Earth crust).As a person ascend up to the Toposphere the temperature continues to reduce because because the heat from the ground is reduced as the heights increased.
It has been proven that as a person ascends into the Toposphere the amount of air and pressure reduces this will eventually lead to expansion of the gas particles which will then reduce the temperature.
You should select Choice-4 .
Explanation:
Value of the cross-sectional area is as follows.
A =
= 3.45 
The given data is as follows.
Allowable stress = 14,500 psi
Shear stress = 7100 psi
Now, we will calculate maximum load from allowable stress as follows.

= 
= 50025 lb
Now, maximum load from shear stress is as follows.

= 
= 48990 lb
Hence,
will be calculated as follows.

= 48990 lb
Thus, we can conclude that the maximum permissible load
is 48990 lb.
