Also, U should try finding out a lot of personal info about them that they dont want anyone to know. also tell the principal. Is ur mom nice, or mean? if shes nice, she'll support u and fight for u, which means u should address
Answer:
h/(m*c)
Explanation:
Hi!
Lets denote the units of X as [X]
Since the dimentions of h are:
![[h] = \frac{ML^{2}}{T}](https://tex.z-dn.net/?f=%5Bh%5D%20%3D%20%5Cfrac%7BML%5E%7B2%7D%7D%7BT%7D)
If we divide [h] by the units of mass, we get:
![\frac{[h]}{[m]} = \frac{L^{2}}{T}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bh%5D%7D%7B%5Bm%5D%7D%20%3D%20%5Cfrac%7BL%5E%7B2%7D%7D%7BT%7D%7D)
Also we know that:
![[c] = \frac{L}{T}](https://tex.z-dn.net/?f=%5Bc%5D%20%3D%20%5Cfrac%7BL%7D%7BT%7D)
So:
![[\frac{h}{mc}] = \frac{L^{2}}{T}}*\frac{T}{L}=L](https://tex.z-dn.net/?f=%5B%5Cfrac%7Bh%7D%7Bmc%7D%5D%20%3D%20%5Cfrac%7BL%5E%7B2%7D%7D%7BT%7D%7D%2A%5Cfrac%7BT%7D%7BL%7D%3DL)
Therefore
h/(mc) has dimentiosn of length
Answer:
Gravitational energy
kinetic energy
Electrical energy
Light energy
Explanation:
When water stored in dams falls freely, the potential energy stored is converted into kinetic energy.
So, it is gravitational energy
As turbines move, it is kinetic energy.
Electricity is produced, it is electrical energy.
For lightening, it is light energy.
Energy is conserved, Energy can neither be created nor be destroyed. It can transform from one form of energy into another.
