<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>
We don't know how many of ANY color are in the bag right now, so there's no way to calculate an answer.
What Tom has to do is make sure that the number of marbles that are NOT blue is NINE TIMES the number of blue ones in the bag.
Answer:
F = 51.3°
Explanation:
The component of weight parallel to the inclined plane must be responsible for the rolling back motion of the car. Hence, the force required to be applied by the child must also be equal to that component of weight:
where,
W = Weight of Wagon = 150 N
θ = Angle of Inclinition = 20°
Therefore,
<u>F = 51.3°</u>
So the equation used in this problem is ΔX=V0*T+1/2AT^2 the X is the distance, v0 is initial velocity, T is time, and a is acceleration. So when we plug these values it we get: 108= 0•T+1/2•3•T^2,the 0•t disappears, and the 1/2•3 gets us 1.5, so we have 108=1.5T^2, then we divide 108 by 1.5 which gets us 72=t^2, and we then take the square root and get 8.49=T so the answer is 8.49 seconds.
Answer:
Correct option : (c) period.
Explanation:
The time that is required for a vibrating object to complete one full cycle is called the time period. If f is the frequency of a wave, then the relation between the frequency and the time period is given by :
These are the characteristics of a wave. Some other characteristics are wavelength, amplitude, intensity etc. So, the correct option is (c) "period".
