Energy is the capacity to do work. Energy exists in various forms in the entire universe.
It may be light,sound,electric,magnetic,kinetic,potential,thermal energy etc.
As per the law of conservation of energy, it is neither created not destroyed. It can change from one form to another form.The total energy of the universe is always constant.
The process in which energy will change from one form to another form is called energy conversion.
There is also another terminology for energy conversion called energy transformation.
Energy transference is the process in which energy will be transferred from one body to another body.
Hence the correct answer to this question will be conversion and transformation
Answer:
Explanation:
We can use the following kinematics equations to solve this problem:
.
Using the first one to solve for acceleration:
.
Now we can use the second equation to solve for the distance travelled by the airplane:
(three significant figures).
Answer:
North and east are at 90 degree, equation becomes
Explanation:
(2x 2)+[2(x+5)] 2=50 2
on solving, we get
x=12.366km/h
Answer:
Considering Tarzan as a point mass at point L and using the equation for a simple pendulum:
P = 2 pi (L / g)1/2
P^2 = 4 pi^2 L / g
L = g P^2 / (4 pi^2) = 9.8 m/s^2 * 7.27^2 s^2 / (4 pi^2) = 13.1 m
Answer:
The answer to the question is A.
Explanation:
The definition of moment is Force multiplied the distance to the point of interest.
So the external moment at point O is equal to ⇒ EMо= F×d
Knowing the definition of moment of inercia (I) and a newtonian Force ( m.a)
We can say that te moment of the externals force at point O is EMо= IGa
Because the rotation of a body in a inmovil point is implicated by the moment of inercia an the action of the gravity in that moment.
