Answer:
360 V
Explanation:
We can use the transformer equation:
where
is the primary (input) voltage
is the number of turns in the primary coil
is the secondary (output) voltage
is the number of turns in the secondary coil
In this problem,
Substituting into the equation, we can find the output voltage:
Id say this is more of a biology question or even a psychology question , well its not a question at all but the endocrine system is a collection of glands that secrete hormones direct to the blood system (circulatory system) to be sent to the desired / target organ , an example of a gland could be the pituitary gland (located towards rear of brain)
Work Done = Force x Distance Moved
Work Done = 25 x 15 = 375 Joules
