Answer:
Explanation:
The problem is based on Doppler's effect , for which expression is as follows
![n = \frac{n_o(V+v_o)}{(V-v_s)}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7Bn_o%28V%2Bv_o%29%7D%7B%28V-v_s%29%7D)
n is apparent frequency , n₀ is original frequency , V is velocity of light , v₀ is velocity of observer and v_s is velocity of source , both coming towards each other.
Putting the values
![n = \frac{262(344+18)}{(344-30)}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B262%28344%2B18%29%7D%7B%28344-30%29%7D)
n = 302 .
Answer:
it will be heavy sweating
Explanation:
because if humans expierment a heavy heat they might be sweating heavly
Answer:
3.7 N/kg
Explanation:
The gravitational strength refers to the amount of gravity acting per unit mass. Hence in this case,
Gravitational Strength = Weight / Mass
= 370 / 100
= <u>3</u><u>.</u><u>7</u><u>N</u><u>/</u><u>k</u><u>g</u>
