Which of the following is the dimension of pressure?
ML-1T-2
MLT-2
ML2T-3
ML-3
Correct answer is A
Pressure = heg
= m x \(\frac{kg}{m^3}\) x \(\frac{m}{5^2}\)
= ML-1T-2
The graphite rods surrounding the uranium fuel rods in a nuclear reactor, are used to
absorb the neutrons and hence halt the nuclear process
create the neutrons and hence slow up the nuclear process
slowdown the neutrons and hence slow up the nuclear process
speed up the neutrons and hence speed up the nuclear process
Correct answer is C

One of the features of the fission process is that
its products are not radioactive
it leads to chain reaction
neutrons are not released
the sum of the masses of the reactants equals the sum of masses of the products
Correct answer is B

In a purely inductive circuit, the current
lags behind the voltage in phase by 90o
leads the voltage in phase by 90o
is in the same phase with the voltage
leads the voltage by 180o
Correct answer is A

50.0Hz
100.0Hz
311.0Hz
314.2Hz
Correct answer is A
V = 311 sin314.2t compare with,
V = V sin2\(\pi\)Ft
2\(\mu\)F = 314.2
F = \(\frac{314.2}{2 \times\ 3.142}\)
F = 50Hz
