How does nuclear fission work?

Physics

LuckyWell [14K]3 years ago
7 0

Current nuclear reactors use nuclear fission to generate power. ... In nuclear fusion, you get energy when two atoms join together to form one. In a fusion reactor, hydrogen atoms come together to form helium atoms, neutrons and vast amounts of energy. It's the same type of reaction that powers hydrogen bombs and the sun.

A wire runs left to right and carries a current in the direction shown. What is the direction of the magnetic field at point Z?
Vanyuwa [196]
The correct option is out of the screen.

As the motion of positive charge is the direction of current in the wire. From the right-hand curl rule, the magnetic field direction will be outside the paper or the screen. As the <span>wire runs left to right and carries a current in the direction from left to right, the magnetic field lines will be outside the screen.</span>

Answer:

<u> Power = 9.75 ×10^8\frac{kgm^2}{s^3}</u>

Explanation:

  • Power is rate of change of energy.
  • Here gravitational energy is transferred to kinetic energy of water at a definite rate.

For one second 650m^3 of water flows out down to 150m oh depth.

So, the energy at a height of 150m is transformed to kinetic energy.

for a second,

       650m^3 of water flows down ⇒ (1000kg/m^3 × 650m^3) = 6.5×10^5kg of warer flos down.

The total gravitational potential energy stored in water is

    = <u>mass of water × height× gravity</u>

    = 6.5 ×10^5 × 150 × 10 =  9.75 ×10^8\frac{kgm^2}{s^2}

As it is transformed in a second it is also equal to <u>Power.</u>
