Answer:
Explanation:
Let the internal resistance be r .
Since in open circuit the volt is 1.55 V , this will be the source voltage .
Source voltage = 1.55
If external resistance be R .
1.55 / (R + r ) = .500
R + r = 3.1 ohm
So sum of internal resistance and external resistance will be 3.1 ohm.
The gravitational pull is weaker.
Answer:
d ) 16 years
Explanation:
If n be number of half years passed then
[/tex]
m is mass undecayed m₀ is original mass
Here m = 6 g
m₀ =24 g
Putting these values
![\frac{6}{24} =\sqrt[n]{\frac{1}{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B24%7D%20%3D%5Csqrt%5Bn%5D%7B%5Cfrac%7B1%7D%7B2%7D%20%7D)
n = 2 half lives
age = 2 x 8 = 16 years
= 16 years
The mitochondria is the powerhouse of the cell because it takes nutrients and breaks it down to provide energy for the cell.
Answer:
See below.
Explanation:
The difference between these two is that a wave is a disturbance of some quantity in space or intermediate while a particle has a definite mass concentrated on a small area.
