Which is a characteristic of a step–down transformer?

Answer:  

Step Down Transformer: The Transformer that expands the voltage from Primary (essential) to Secondary (auxiliary) (more optional twisting turns than essential winding turns) loops called Step Down Transformer.

Explanation:

A transformer that reduces high voltage to low voltage is called a step-down transformer. The step-down transformers are that transformers which have high turns on its primary coils than secondary.  

Where  

Vp = Voltage in Primary Coil  

Ip = Current in Primary Coil  

Vs = Voltage in Secondary Coil  

Is = Current in Secondary Coil

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
