<span>It is true that all nuclear energy results in
the rapid release of energy, such as in atomic bombs. <span>A process wherein the atom’s nucleus
is further divided into two nuclei, that is, fission products, is called
nuclear fission. This happens when the nuclei of radioactive elements (e.g.
Uranium or Plutonium isotopes) are able to attract neutrons. Because these
isotopes’ nuclei are unstable, an addition to their energy causes them to
divide into new pieces of neutron. In nuclear reactors, fission occurs when the
power plant gathers heat from a steam in a physical process. Nuclear reactors
are designed to sustain nuclear chain reactions.</span></span>
Answer:Stirring.
Explanation:Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster.
Answer:
<h2>1.5 ohms</h2>
Explanation:
Power is expressed as P = V²/R
R = resistance
V = supplied voltage
Given P = 600W and V = 30V
R = V²/P
R = 30²/600
R = 900/600
R = 1.5ohms
magnitude of its resistance is 1.5ohms
Answer:
Explanation:
When an amount of energy Q is supplied to a sample of substance of mass m, the temperature of the substance increases by 
according to the equation
where
is the specific heat capacity of the substance
In this problem, we have:
m = 55.0 g is the mass of the sample of silver
is the amount of energy supplied to the sample
is the change in temperature of the sample
Solving the equation for , we find the specific heat capacity of silver:
Answer:
144 watt
Explanation:
resistance, R = 100 ohm
L = 4 mH
C = 100 micro farad
At resonance, the impedance is equal to R
Z = R
Vrms = 120 V
Irms = Vrms / R = 120 / 100 = 1.2 A
Power is given by
P = Vrms x Irms x CosФ
Where, CosФ is called power factor
At resonance, CosФ = 1
Power, P = Irms x Vrms
P = 1.2 x 120 x 1
P = 144 Watt.
Thus, the power is 144 watt.
