I answered this question the answer is about 4039200
Answer:
Explanation:
All the energy in oil, gas, and coal originally came from the sun, captured through photosynthesis.for example when we burn wood to release energy that trees capture from the sun, we burn fossil fuels to release the energy that ancient plants captured from the sun. We can think of this energy as having been deposited in a natural solar power bank over millions of years.
So, in one sense, gasoline-burning cars, coal-burning power plants, and homes heated by natural gas are all solar powered!
Rise over run at 1 second
It’s the same slope from 0 to 2 seconds
10/2=5mps
As a note all time points between 0and 2 will have this instantaneous velocity
Instantaneous velocity at time 2 is 0
Answer:
h = 3.10 m
Explanation:
As we know that after each bounce it will lose its 11% of energy
So remaining energy after each bounce is 89%
so let say its initial energy is E
so after first bounce the energy is
![E_1 = 0.89 E](https://tex.z-dn.net/?f=E_1%20%3D%200.89%20E)
after 2nd bounce the energy is
![E_2 = 0.89(0.89 E)](https://tex.z-dn.net/?f=E_2%20%3D%200.89%280.89%20E%29)
After third bounce the energy is
![E_3 = (0.89)(0.89)(0.89)E](https://tex.z-dn.net/?f=E_3%20%3D%20%280.89%29%280.89%29%280.89%29E)
here initial energy is given as
![E = mgH_o](https://tex.z-dn.net/?f=E%20%3D%20mgH_o)
now let say final height is "h" so after third bounce the energy is given as
![E_3 = mgh](https://tex.z-dn.net/?f=E_3%20%3D%20mgh)
now from above equation we have
![mgh = (0.89)(0.89)(0.89)(mgH)](https://tex.z-dn.net/?f=mgh%20%3D%20%280.89%29%280.89%29%280.89%29%28mgH%29)
![h = 0.705H](https://tex.z-dn.net/?f=h%20%3D%200.705H)
![h = 0.705(4.4 m)](https://tex.z-dn.net/?f=h%20%3D%200.705%284.4%20m%29)
![h = 3.10 m](https://tex.z-dn.net/?f=h%20%3D%203.10%20m)
Answer:
![w= 1.867\times10^{-2}](https://tex.z-dn.net/?f=w%3D%201.867%5Ctimes10%5E%7B-2%7D)
Explanation:
Given:
fibers diameter d= 18 μm
distance of the screen D= 30 cm
wavelength λ= 560 nm
we know that fringe width
![w=\frac{2\lambda D}{d}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B2%5Clambda%20D%7D%7Bd%7D)
putting values we get
![w=\frac{2\times560\times10^{-9}\times0.3}{18\times10^{-6}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B2%5Ctimes560%5Ctimes10%5E%7B-9%7D%5Ctimes0.3%7D%7B18%5Ctimes10%5E%7B-6%7D)
![w= 1.867\times10^{-2}](https://tex.z-dn.net/?f=w%3D%201.867%5Ctimes10%5E%7B-2%7D)
