The answer is X. I hope this helped
Given that,
Mass, m = 250 g
Volume of the container, V = 50 cm³
To find,
The density of the oil.
Solution,
Density = mass/ volume
The computation for density is as follows :
So, the density of the oil is 
.
If the pressure acting on a given sample of an ideal gas at constant temperature is tripled, the volume is reduced to one-third of its original value. <em>(a)</em>
Answer:
To produce magnetic field
Explanation:
When current passes through a coil in presence of magnetic field then torque is produced in it.This is the working principle of motor.
The relationship between inductance and frequency can be clearly described using the following equation of inductive reactance:
Xl = 2*pi*f*L ; simplifying:
L = Xl / 2*pi*f
Therefore, as what we saw, inductance and frequency are inversely proportional. To add up, when inductance increases the frequency would decrease.
