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

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
66m
136m
264m
528m
Correct answer is B
2 × Distance = speed × time
2 × Distance = (340) × (0.8)
= 272/2
Distance = 136m
0.33
0.50
1.50
3.00
Correct answer is C
Weight in Air = 45N
Weight in Water = 15N
R.D = \(\frac{45}{45-15}\) = 1.50
