Amar Kumar 7 years, 7 months ago

Work is the energy required to move an object against a force. Work is equal to the force times the distance the object moves.

W = F * s where W is work, F is force, and s is the displacement.

The SI unit for work is the joule.The SI units for work are the joule (J) or newton-meter (N * m) .

Naveen Sharma 7 years, 7 months ago

Given $T = k p^a d^b E^c$

where k is a proportionally constant.
Substituting the dimensions of T, p, d and E,
we have
$[T] = [[ML^{-1}T^{-2}]^ a [ML^{-3}]^ b [ML^2T^{ -2}]^ c$

Equating power of M, L, and T on both sides, we have
a + b + c = 0
–a –3b + 2c = 0
–2a – 2c = 1
Solving these equations, we get $a = {-5\over 6}, \ b = {1\over 2} \ and \ c ={ 1\over 3}$
