I'm pretty sure the energy an object acquires when exposed to a force is known was potential energy.
The answer to this statement is true!
Formula for kinetic energy is 1/2mv^2 so that answer should most probably be 94521.6J
Answer:
B. Axial stress divided by axial strain
Explanation:
Elasticity:
It is the tendency of an object to deform along the axis when an opposing force is applied without facing permanent change in shape.
Plasticity:
When an object crosses the elasticity limit, it enters plasticity where the change due to stress is permanent and the object might even break.
Yield strength:
Yield strength is the point of maximum bearable stress that indicates the limit of elasticity.
Our case:
As the stress applied is less than the yield strength, the rod is still in the elasticity state and its modulus can be calculated.
Modulus of Elasticity = Stress along axis/Ratio of change in length to original length
Axial strain is basically the ratio of change in length to original length.
So, Modulus of Elasticity = Axial Stress/ Axial Strain
The electrical energy consumed by a toaster is 0.033 Kwh.
<u>Explanation</u>:
The power utilized by the toaster is 400 W.
The toaster is operated for 5 Minutes.
We know that,
Substitute the values in the above formula to obtain electrical energy,
Electrical energy = 0.4 × 0.083
Electrical energy is 0.033 Kwh.
