State the formula of kinetic energy fast
Answers
Explanation:
Translational kinetic energy of a body is equal to one-half the product of its mass, m, and the square of its velocity, v, or 1/2mv2. ... Relativistic kinetic energy is equal to the increase in the mass of a particle over that which it has at rest multiplied by the square of the speed of light.
Answer :
★ sebaceous glands are holocrine glands that produce sebum, a semiliquid mixture of glandular cell debris containing glycerides, free fatty acids, wax esters, squalene, cholesterol, and cholesterol esters.
★ Sebaceous glands are present everywhere on the human skin except for the palms, soles, and dorsa of the feet.
★ Generally, they are associated with hair follicles and empty through a short duct
★ into the canal of the hair follicle.1 The sebaceous glands are holocrine glands that produce sebum,
★ a semiliquid mixture of glandular cell debris containing glycerides, free fatty acids, wax esters , squalene, cholesterol, and cholesterol esters. The largest and most numerous sebaceous glands are found on the face, scalp, chest, and back.

Kinetic energy :
★ From equations of motion, the relation connecting the initial velocity (u) and final velocity (v) of an object moving with a uniform acceleration a, and the displacement, s is But from
Newton’s second law of motion
F = m a
work done by the force, F is written as the following:
If the object is starting from its stationary position, that is, u = 0, then From work and energy theorem, work done is equal to the change in the kinetic energy of the object.
w = (1/2) mv^2
If u = 0,
the work done will be,
Thus the kinetic energy possessed by an object of mass, m and moving with a uniform velocity, v is
K.E = (1/2) mv^2
