National University of Science and Technology NUST is top rated engineering university of Pakistan. NUST was founded in 1991 with an aim of providing quality education. NUST grow up dramatically in a very little time period because of their focus and dedication toward their work. NUST provide vast range of undergraduate and Master’s programs for their students. Due to their high standards and quality of education their fee structure is also high and not everyone is able to afford that. Keeping that in mind they started different scholarship programs for needy students. NUST need based scholarship program welcome every student who doesn’t have enough sources to pay the fee, NUST also provides interest free loans and provides facility of paying fee in installments. But in order to get scholarship in NUST candidates must pass their entry test exam, NUST entry test exam is considered to be the toughest engineering test in Pakistan. Every year thousands of students apply to get admission in NUST through NET. Candidates must prepare themselves fully if they want to secure a seat.

If a body is rolling down a slope WITHOUT slipping, then the total Kinetic energy will have which of the following components:
- Translational Kinetic Energy
- Rotational Kinetic Energy
- Energy lost in friction
- 1,2 and 3
- 1 and 3
- 1 and 2 only
- 2 only
1 and 2 only
Since the body is moving downwards without slipping, so the frictional force will not be added in the total K.E of the rolling body. The rest of two will be present.
How many electrons are there in 1 columb of charge?
- 3.1 X 1019
- 1.9 X 1019
- 6.2 X 1018
6.2 X 1018
If the charge on the electron is e= 1.6 x 1019C. Then 1 columb of charge there will be: number of electrons = 1/1.6 x 10-19; which is 6.2 x 1018 electrons.
Heat & Thermodynamics
Internal energy of the ideal gas is equal to translational KE based on which of the following assumptions?
- Ideal gases expand when heated
- Molecules of ideal gas exert constant force on each other
- Molecules of ideal gas exert no force on each other
- Both A & B
Molecules of ideal gas exert no force on each other
Molecules of ideal gas are mere points that exert no force on each other, therefore, internal energy of ideal gas = translational KE.
