Yes you are right cuz charging by friction cant be done in fluids( liquid and gas)
Answer:
"8 units" is the appropriate answer.
Explanation:
According to the question,
Throughout equilibrium all particles are of equivalent intensity, and as such the integrated platform's total energy has been uniformly divided across all individuals.
Now,
The total energy will be:
= ![480+720](https://tex.z-dn.net/?f=480%2B720)
= ![1200 \ units](https://tex.z-dn.net/?f=1200%20%5C%20units)
The total number of particles will be:
= ![50+100](https://tex.z-dn.net/?f=50%2B100)
= ![150](https://tex.z-dn.net/?f=150)
hence,
Energy of each A particle or each B particle will be:
= ![\frac{1200}{150}](https://tex.z-dn.net/?f=%5Cfrac%7B1200%7D%7B150%7D)
= ![8 \ units](https://tex.z-dn.net/?f=8%20%5C%20units)
Answer:
d = 10.076 m
Explanation:
We need to obtain the velocity of the ball in the y direction
Vy = 24.5m/s * sin(35) = 14.053 m/s
To obtain the distance, we use the formula
vf^2 = v0^2 -2*g*d
but vf = 0
d = -vo^2/2g
d = (14.053)^2/2*(9.8) = 10.076 m
<span>Volume of cylinder = pi*r*2*L
As, from the above formula,volume is directly proportional to length,
So, if we increase in length also increases in volume by 0.22%
we know
</span><span>density=<span><span>mass/</span><span>volume
As, density is inversely proportional to volume it means increasing in volume decreases the density by 50.22%
