Answer:
d. According to the previous theorem:
(kh^2)/2-mgh-(m(2v)^2)/2=0,
126h^2-2.577h-8.236=0,
h=0.266 m.
Explanation:
Answer:
When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side.

As we know that length of the Boeing plane is

width of the intersection is given as

now we know that deceleration of the plane is given as

Also the final speed of the plane while it clears the intersection is given as

now we have


also we know that


now we have

by solving above equation we have

Answer:


- Energy increases
Explanation:
From the question we are told that
Work done 
a)Generally the heat flow for an adiabatic process is 0 (zero)


b)Generally Change in internal energy of gas is mathematically given by
Since 
Therefore

Giving


c)With increases in internal energy brings increase in temperature
Therefore
Energy increases
