Answer:
Solids
Explanation:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.
In the balanced nuclear reaction of uranium 235, we have thorium 231, helium atom and energy released at the right of the equation
<h3>
Balanced nuclear reaction of Uranium</h3>
The balanced nuclear reaction of uranium is determined as follows;
Thus, in the balanced nuclear reaction of uranium 235, we have thorium 231, helium atom and energy released at the right of the equation while uranium 235 is on the left hand side of the nuclear reaction equation.

Answer: Gravity causes a change in the mass of objects on earth and the moon.
Explanation:
Because of gravity, the weight of objects lessen, and decrease because of gravity. If you were to drop an object from earth from space, the object would have more mass. Hope that helps.
(a) The voltage that is produced in the secondary circuit is 1,800 V.
(b) The current that flows in the secondary circuit is 1 A.
<h3>Voltage in the secondary coil</h3>
Np/Ns = Vp/Vs
where;
- Np is number of turns in primary coil
- Ns is number of turns in secondary coil
- Vp is voltage in primary coil
- Vs is voltage in secondary coil
100/1500 = 120/Vs
Vs = (120 x 1500)/100
Vs = 1,800 V
<h3>Current in the secondary coil</h3>
Is/Ip = Vp/Vs
where;
- Is is secondary current
- Ip is primary current
Is = (IpVp)/Vs
Is = (15 x 120)/1800
Is = 1 A
Thus, the voltage that is produced in the secondary circuit is 1,800 V.

<span>Carbon atom showing 6 protons as electro positive charge in its nuclei should have same no of -ve charged electrons , that is 6 electronns in its radii to make an atom of C as a neutral element , for that each element in its atomic state should have equal no of protons and electrons , the no of neutrons which has no electric charge and almost negligible weight does play significant role except contributes to isotopes of the given atom or an element, so C atom having 6 protons should have 6 electrons</span>
