Words that are used before a noun to give the precise meaning of the noun are called determiners. These are short, common words..
Solution:
Work done (W) = 250 J Force applied (F) = 10 N Distance (S) = ? W = F x S Distance covered = 2..
Work done (W) = 250 J Force applied (F) = 10 N Distance (S) = ? W = F x S Distance covered = 2..Solution:
W = F x S Force acting on the object is given by F = mg [Newton's second law of motion] Mass of the object (m) = 5 kg Distance moved = 2m Therefore, Work done = F x S = 98 J 02. How much work is done, when a force of 25 N displaces an object through 10 m, in the direc..

Heat absorbed by the system = 470 J or q = 470 J Work done by the system = 200 J or w = - 200 J According to first law of thermodynamics D E = q + w D E = 470 - 200 = 270 J 3. A gas absorbs 120 J of heat and expands against the external pressure of 1.10atm from a volume of 0.5L to 2.0L..
Solution:
Mass of the bag of rice = 75 kg Work done = 4900 J Work done in lifting the bag of rice is stored in it as its potential energy. Therefore, Potential energy = mgh Height = 6.67..
Mass of the bag of rice = 75 kg Work done = 4900 J Work done in lifting the bag of rice is stored in it as its potential energy. Therefore, Potential energy = mgh Height = 6.67..Solution
13. The enthalpy change involved in the oxidation of glucose is - 2880 kJ mol - 1 . Twenty five percent of this energy is available for muscular work. If 100 kJ of muscular work is needed to walk one kilometer, what is the maximum distance that a person will be able to walk afte..
Solution:
The work done in lifting coal is nothing but gravitational potential energy. Mass of coal = 10 5 kg Time = 1 hour = 60 x 60 s = 3600 s Power of the eng..
