Answer:
No. some cons is that it is unproven, commercial plants will be very expensive to run and build and it is very hot
Explanation:
btw it is <u>Fusion research.</u>
There are many ways to calculate force. However, they are completely different aspects. The force on an area is pressure, so F = p*A. In magnetic fields you use another formule (forgot the formule atm). Unless you define what kind of force you are looking for, I can't help you any further.
Explanation :
We know that the resistance of the wire is given by :

Where
is the resistivity
l is the length of the wire
A is the area of the wire.
Another factor on which the resistance of wire depends is temperature. It is given by :
![R=R_{ref}[1+\alpha (T-T_{ref})]](https://tex.z-dn.net/?f=R%3DR_%7Bref%7D%5B1%2B%5Calpha%20%28T-T_%7Bref%7D%29%5D)
So, it is clear that the resistance of the wire is directly proportional to the temperature. It we want to decrease the resistance of the piece, its temperature should be decreased.
So, the correct option is (3) " decreasing the wire’s temperature ".
Answer:
p = mv
v = p/m
m = p/v
Explanation:
The momentum
is given by the following equation:
(1)
Where:
is the mass of the object
is the velocity of the object
If we isolate
from (1):
(2)
If we isolate
from (1):
(3)
As we can see equations (1), (2) and (3) show the relationships among momentum, mass, and velocity.
