Answer:
The work done required is
Explanation:
Given that,
Stretch spring = 2 cm
Stretch spring = 1 cm
We need to calculate the work done
Using formula of work done
Put the value into the formula
.....(I)
We need to calculate the work done
Using formula of work done
Put the value into the formula
.....(II)
We need to calculate the work done
Using equation (I) and (II)
Hence, The work done required is
The equation that relates the voltages and the number of turns in a transformer is
where
is the voltage in the secondary coil,
is the voltage in the primary coil, and
and
are the number of turns on the secondary and primary coils.
Using the numbers, we find the ratio between the number of turns:
Answer:
inches and feet (or even centameters)
Explanation:
these are all common units used to measure height
