Registration date for the entry test of University of Health Sciences Lahore (UHS) is 19th July 2019 until 29th July 2019. UHS has announced its syllabus for MCAT 2020. Syllabus is same as last year. Punjab MCAT test is based on four subject’s major subjects Physics, Chemistry, Biology, and English. UHS MCAT test is very competitive, every year thousands of students appear in it to get admission in Medical colleges, but only those students get selected who perform good in MCAT.

The energy obtained in a nuclear reaction is derived from
- Mass defect and binding energy
- All of these
All of these
The sum of the individual masses of the parts of a nucleus is less than their mass when they are bound into the nucleus producing mass defect. The mass from the mass defect is converted into the energy that holds the nucleus together and is released in fission. Fusion also produces energy when individual nuclei are forced to combine (fusion) and form new elements in a process that produces energy.
Waves and Oscillations
Waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave are called?
- Traverse waves
- Electromagnetic waves
- Compression waves
- None of the above
Longitudinal waves, also known as “l-waves”, are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave. Mechanical longitudinal waves are also called compressional waves or compression waves, because they produce compression and rarefaction when travelling through medium. The other main type of wave is the transverse wave, in which the displacements of the medium are at right angles to the direction of propagation.
Current flowing between two input terminals of operational amplifier is?
- In the range of milli amperes
- In the range of amperes
- None of the above
Input resistance of operational amplifiers is very high in the range of mega ohms. Therefore, practically no current flow between the two input terminals.
