<span>Answer: V/n = constant</span>
Answer:
Matter is anything that has mass and takes up space. A mixture is matter that can vary in composition.....because, the substances in a heterogeneous mixture are not evenly mixed, two samples of the same mixture can have different amounts of the substance....
Hope this answer help u!!!!

(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.

The answer is 54.675 J
<span>The kinetic energy (Ke) of an object is the product of half of its mass (m) and the square of its velocity (v²):
</span>Ke = 1/2 m * v²
We have:
Ke = ?
m = 15 kg
v = 2.7 m/s
_____
Ke = 1/2 * 15 kg * (2.7 m/s)² = 1/2 * 15 kg * 7.29 m²/s² = 54.675 kg * m²/s²
Ke = 54.675 J
A sphere has reflection symmetry across any plane through its center.
