Transformer contains two coils: primary and secondary. They allow change of voltage to lower or higher value. In first case we have step-down and in second case we have step-up transformer.
Formula used for transformer is:
Where:
N1 = number of turns on primary coil
N2 = number of turns on secondary coil
V1 = voltage on primary coil
V2 = voltage on secondary coil
In a step-down transformer primary coil has more turns than secondary coil. So the ratio 1:29 means that for each turn on secondary coil we have 29 turns on primary coil.
We can solve the equation for V2:
Secondary coil provides voltage of 4.14V.
Answer:
C: Mass of body
Explanation:
Upthrust is defined as the upward force that a liquid will exert on a body floating atop it.
Now, Formula for upthrust is;
Upthrust = density of liquid × volume of the body × acceleration due to gravity.
From the formula, we can see that upthrust depends on density, volume and acceleration due to gravity.
Thus, looking at the options, the one that doesn't apply is mass of body.

Explanation:
When a 2 m long wire carrying 2 A of current pointing to the right is placed in a magnetic field of 4 T directed away from you then the force on the wire point down, therefore the correct option is D
<h3>What is a magnetic field?</h3>
A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted.
According to Fleming's left-hand rule, A force perpendicular to the field and the direction of the current flow is experienced by a current-carrying conductor when it is placed in an external magnetic field.
Thus, The correct answer is D because the force on a 2 m long wire carrying 2 A of current pointing to the right when placed in a magnetic field of 4 T directed away from you causes the wire to point downward.
