hertz
farad
Correct answer is C
The unit of frequency is hertz, abbreviated Hz.
3.3°C
7.0°C
13°C
30.0°C
Correct answer is D
Let the room temperature be X.
We have, \(\frac{3-0}{10-0} = \frac{X-0}{100-0}\)
\(\frac{3}{10} = \frac{X}{100}\)
\(X = \frac{3 \times 100}{10}\)
= 30°C
An object at rest is said to possess
potential energy
kinetic energy
chemical energy
electrical energy
Correct answer is A
Potential energy is the energy that is stored in an object due to its position relative to some zero position
Which is the incorrect formula for a body accelerating uniformly?
a = v2 − \(\frac{u^2}{2}\)
v2 = u2 + 2as
s = ut + \(\frac{1}{2}\) at2
v2 − u2= 2as
Correct answer is A
Look through the equations of motion
\(\Delta\)x . \(\Delta\)p = h
\(\Delta\)x . \(\Delta\)p \(\leq\) = h
\(\Delta\)x . \(\Delta\)p \(\geq\) = h
\(\Delta\)x . \(\Delta\)p > h
Correct answer is C
