500J
Explanation:
Given parameters:
Weight of the body = 50N
Height = 10m
Unknown:
Work done = ?
Solution;
Work done is the force that moves a body through a particular distance in the direction of the force.
In this problem, we can solve the problem by relating work done to the potential energy used in lifting the mass.
The weight on a body, a force in the presence of gravity
weight(weight) = mg
where m = mass of body
g = acceleration due to gravity
Work done = Fxd
Where F = force on the body
d = distance moved
Potential energy = mgh
where h is the height
P.E = work done = Weight x height = 50 x 10 = 500J

A build up of charges on a sock from a dryer
Heat is added to the mass as follows:
Q_-14-0 = mC_iΔT = 39*2.06*(0--14) = 39*2.06*14 = 1124.76 J
Q_0 = mC_f = 39*334 = 13026 J
Q_0-100 = mC_wΔT = 39*4.18*100 = 16302 J
Q_100 = mC_v = 39*2230 = 86970 J
Q_100-108 = mC_sΔT = 39*2.03*(108-100) = 39*2.03*8 = 633.36J
Q = Summation of all the heats added = 1124.76+13026+16302+86970+633.36 = 118056.12 J ≈ 118.06 kJ

Answer:
The answer to your question is 784.8 J. None of your answer, did you forget some information?
Explanation:
Data
mass = 20 kg
distance = 4 m
work = ?
Formula
Work = force x distance
Force = mass x gravity
Process
1.- Calculate the weight of the block
Weight = 20 x 9.81
Weight = 196.2 N
2.- Calculate the work done
Work = 196.2 x 4
Work = 784.8 J
