Keiko builds a transformer in the lab, but it does not decrease the voltage as much as she needs. what should keiko change to further reduce the voltage?

Answer

D. She should increase the number of coils in the primary winding.

Explanation

A transformer is a device that is used to step down or step up a the voltage.

It has two coils, primary and secondary that are used to determine how much the voltage changes.

To decrease the voltage the ratio of number of coils in the primary to the number of coils in the secondary should be big.

To reduce the voltage, D. She should increase the number of coils in the primary winding.

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
