momentum
Inertia
impulse
Energy
Correct answer is B
Inertia is the resistance of the object to any change in its motion, including a change in direction. An object will stay still or keep moving at the same speed and in a straight line, unless it is acted upon by an external unbalanced force.
The diagram above illustrates a simple barometer. Which distance measures the atmospheric pressure?
PQ
QR
RS
QS
Correct answer is B
The height of the mercury column in a simple barometer is calculated as the atmospheric pressure.
The general definition of elastic modulus is
\(\frac{stress}{strain}\)
\(\frac{strain}{stress}\)
\(stress \times strain\)
\(\sqrt{\frac{stress}{strain}}\)
Correct answer is A
Elastic modulus is the ratio of pressure (stress) applied to a body to the resistance (strain) produced by the body.
= \(\frac{stress}{strain}\)
The S.I unit for sound energy is
Hz
cd
dB
J
Correct answer is D
Every form of energy is measured in joules (J).
0.56
1.50
1.79
2.02
Correct answer is C
N = \(\frac{1}{sinθ}\)
= \(\frac{1}{sin34}\)
= 1.79
