Answer:

A very large amount of energy is produced from a series of chemical reactions.

Explanation:

Nuclear fission is the process of splitting apart nuclei (usually large nuclei). When large nuclei, such as uranium-235, fissions, energy is released. So much energy is released that there is a measurable decrease in mass, from the mass-energy equivalence. This means that some of the mass is converted to energy.

3) If an electrical appliance has 150.0 V applied causing a current of 2.34 amps, what is the
eimsori [14]

The resistance of the appliance is 64.1 Ω.

<u>Explanation:</u>

As per the Ohm's law, which states that the electric current is in direct proportion to the voltage and is in inverse proportion to the resistance. It is given by the expression as,

V = IR

Where V is the voltage (V) = 150.0 V

I is the current (amps) = 2.34 amps

R is the resistance (ohm) or Ω = ?

Now we have to rearrange the equation to get the resistance as,

$R = \frac{V}{I}

Now we have to plug in the values as,

$ R = \frac{150}{2.34}

   = 64.1 Ω

So the resistance of the appliance is 64.1 Ω.
