Answer:
No, it is not a good assumption
Explanation:
From the given information:
The work Jessie did was quite more than the work done by the force of gravity. This is because the gravity of the force on her body is perpendicular to its motion and the work done by Jessie is due to the muscular force of her body. Hence, the total power she produced is more than the calculated amount.
Answer:
Consider frames X and Y:
If X sees Y moving to his right then Y must see X moving to his right.
If this is not true then one can choose one frame over the other ( a favored frame and this is not allowed)
1 .tomato is a vegetable
2. Potato is a vegetable
3. Yes
Answer:
Explanation:
![x = k\times a^m\times t^n](https://tex.z-dn.net/?f=x%20%3D%20k%5Ctimes%20a%5Em%5Ctimes%20t%5En)
k is constant , it is dimension is zero. Using dimensional unit , we cal write the relation as follows
L = ![(LT^{-2})^m(T)^n](https://tex.z-dn.net/?f=%28LT%5E%7B-2%7D%29%5Em%28T%29%5En)
= ![L^mT^{-2m+n}](https://tex.z-dn.net/?f=L%5EmT%5E%7B-2m%2Bn%7D)
Equating power of like items
m=1
-2m+n = 0
n = 2
