Conserved
Explanation:
The first law of thermodynamics states that energy in a systems is "conserved".
This law is the law of conservation of energy of energy. It states that:
"in an isolated system, energy can neither be created nor destroyed but it is transformed from one form to another".
- This simply shows that energy is conserved in an isolated system.
- In an isolated system, there is no exchange of energy with the environment.
- Also, energy is neither formed nor destroyed but transformed.

Centripetal force is give by F = mv^2/r
Since
F = ma
The acceleation accoiated with this centripetal force is
a=v^2/r
the radius is found by r=d/2=5.75m
velocity is found by
v=d/t
distance is the circumference of the circle
c=pi*d=11.5*3.14=36.11m
time=60s/30.6rpm=1.96s
v=36.11/1.96=18.423m/s
plugging this back in to
a=v^2/r=(18.423m/s)^2/5.75m=59.027m/s^2</span>
Answer:
The kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.

Answer:
The magnitude of the electric field inside the membrane is 8.8×10⁶V/m
Explanation:
The electric field due to electric potential at a distance Δs is given by
E=ΔV/Δs
We have to find the magnitude electric field in the membrane
Ecell= -ΔV/Δs
![E_{cell}=-\frac{V_{in}-V_{out}}{s} \\E_{cell}=\frac{V_{out}-V_{in}}{s}\\E_{cell}=\frac{0.070V}{8*10^{-9}m } \\E_{cell}=8.8*10^{6}V/m](https://tex.z-dn.net/?f=E_%7Bcell%7D%3D-%5Cfrac%7BV_%7Bin%7D-V_%7Bout%7D%7D%7Bs%7D%20%5C%5CE_%7Bcell%7D%3D%5Cfrac%7BV_%7Bout%7D-V_%7Bin%7D%7D%7Bs%7D%5C%5CE_%7Bcell%7D%3D%5Cfrac%7B0.070V%7D%7B8%2A10%5E%7B-9%7Dm%20%7D%20%5C%5CE_%7Bcell%7D%3D8.8%2A10%5E%7B6%7DV%2Fm)
The magnitude of the electric field inside the membrane is 8.8×10⁶V/m
Answer:
Explanation:
Energy = volt x charge
= 12 x 750000 J
= 9000,000 J
Latent heat of vaporisation
= 2260000 J / kg
kg of water vaporised
= 9000,000 / 2260000
= 3.982 kg .
