acceleration = change in velocity /change in time
convert 40km to meter then divide it with 5
Near the surface of reflection, reflected wave may interfere with incident wave leading to production of constructive and as well as destructive interference. This in turn, can result to resonance as well as enhancement of the sound intensity as the waves of reflection adds to incident wave. Therefore, the girl would higher intensity of reflected waves as compared to incident waves.
Therefore, statement A is correct.
The answer is C the temp of water in both beakers will decrease since the metal is flowing heat into the water. Therefore we can say the metal losses heat and the water gains the heat lost by the metal minus any heat loss to surroundings! Hope this explanation helps you understand the concept! Please rate if I helped you! Thank you so much!
Given:
The given value is 
.
To find:
The value of the given expression by using the Binomial approximation.
Explanation:
We have,
It can be written as:
![[\because (1+x)^n=1+nx]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%281%2Bx%29%5En%3D1%2Bnx%5D)
Therefore, the approximate value of the given expression is 1.0002.
