The input voltage is 120 V and the transformer is a step up transformer due to increase in the voltage induced in the secondary coil.
<h3>
Input voltage </h3>
The input voltage of the transformer is the voltage of the primary coil and it is calculated as follows;
Ns/Np = Es/Ep
where;
- Ns is the number of turn in the secondary coil
- Np is the number of turn in the primary coil
- Es is the secondary voltage
- Ep is the primary voltage
2X/X = 240/Ep
2 = 240/Ep
Ep = 240/2
Ep = 120 V
Thus, the transformer is a step up transformer due to increase in the voltage induced in the secondary coil.

The answer is D. Sound insulators prevent sound from being transmitted better than elastic solids because sound insulators basically muffle and block the sound waves.
Mendeleev watched that tellurium has compound properties like different components in its gathering, and he didn't realize that neutrons cause the more noteworthy nuclear mass. Mendeleev expressed that he anticipated that tellurium would have a lower nuclear mass than iodine.
If Earth were 10.0 times farther away from the Sun than it is now, 100 times weaker would the gravitational force between the Sun and Earth.
What is Gravitational Force?
According to Newton's universal law of gravitation, The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them.
What causes gravitational force?
Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.
