Answer:
I think c is correct options....
Explanation:
The resistance of the wire increases with increase in temperature. The resistance does not depend on the weight of the wire. Therefore, the correct option is weight.
Answer:
creo que es la opcion numero 4.
Answer:
v = 15 [m/s]
Explanation:
To solve this problem we must use the principle of conservation of linear momentum, which tells us that momentum is equal to the product of mass by Velocity.

where:
P = linear momentum [kg*m/s]
m = mass = 2 [kg]
v = velocity = 15 [m/s]
![P=2*15\\P=30 [kg*m/s]](https://tex.z-dn.net/?f=P%3D2%2A15%5C%5CP%3D30%20%5Bkg%2Am%2Fs%5D)
Since we know that momentum is conserved, that is, all momentum is transferred to the second body, we can determine the velocity of the second body, since the mass is equal to that of the first body.
![30=2*v\\v = 30/2\\v = 15 [m/s]](https://tex.z-dn.net/?f=30%3D2%2Av%5C%5Cv%20%3D%2030%2F2%5C%5Cv%20%3D%2015%20%5Bm%2Fs%5D)
The paragraph is going to be your responsibility but I can provide the pros and cons.
Advantages include the fact that Uranium is a plentiful resource, it is relatively clean, and it takes very little resources to make power.
However disadvantages include radioactive byproducts which need longtime storage. Uranium is also a nonrenewable resource, meaning it can run out. Additionally safety issues regarding melt downs are a major concern.
