The length of the wrench which is also the radius of the circle made by the wrench is
The force is
The angle is
Generally the torque generated by the bolt is mathematically represented as
=>
=>
Yeah, because of it's short frequencies, ultraviolet rays can travel through empty space- D
: D
D it’s definitely D if I’m wrong sorry…
Answer:
The two forms of energy that increase during the time after take off are;
1) The kinetic energy KE
1) The potential energy PE
Explanation:
1) Given that the airplane is accelerating, we have that the velocity, v, of the airplane is increasing, such that the we have the kinetic energy, KE, for a given mass, m, of the airplane increasing as follows;
KE₂ = 1/2×m×v₂² > KE₁ = 1/2×m×v₁²
2) Also, as the height, h, of the airplane increases during the ascent, we have that the potential energy increasing along side as follows;
PE₂ = m × g × h₂ > PE₁ = m × g × h₁
Therefore, the two forms of energy that increase during the time after take off are the kinetic and the potential energy.
