Two cars, one in front of the other, are traveling down the highway at 53.7 m/s. The car behind sounds its horn, which has a fre
1 answer:
Answer:
Explanation:
The source is approaching the observer which is moving away from the source , so applying Doppler's effect
where n is apparent frequency , n₀ is original frequency , V₀ is velocity of observer , V_S is velocity of source , V is velocity of sound
Putting the given values
=
= 536
So apparent frequency will be same as original frequency .
ie 536 .

To solve this problem, we will start by defining each of the variables given and proceed to find the modulus of elasticity of the object. We will calculate the deformation per unit of elastic volume and finally we will calculate the net energy of the system. Let's start defining the variables
Yield Strength of the metal specimen
Yield Strain of the Specimen
Diameter of the test-specimen
Gage length of the Specimen
Modulus of elasticity
Strain energy per unit volume at the elastic limit is
Considering that the net strain energy of the sample is
Therefore the net strain energy of the sample is
