Answer:
The output power is 2 kW
Explanation:
It is given that,
Number of turns in primary coil,
Number of turns in secondary coil,
Voltage of primary coil,
Current drawn from secondary coil,
We need to find the power output. It is equal to the product of voltage and current. Firstly, we will find the voltage of secondary coil as :
So, the power output is :
or
So, the output power is 2 kW. Hence, this is the required solution.
Could there be any options to this one?
Answer:
u =0.269
Explanation:
To find the coefficient of friction we know the following formula
Where
= Force of Friction
= Coefficient of Friction
= Normal Force
Thus we first find the Normal force (N). Remember that the Normal force is perpendicular to the surface, and is equal to the opposing component of Weight (W). Since the surface here is horizontal, then the Normal force will be equal to the Weight.
Now we find the Force on the spring that caused the extension of 3.25cm or 0.0325m
Where
= Force of Friction
= Force Constant
= extension
Hence
Now to find the coefficient of friction we use the first formula

The correct word to fill in the blank is:
<u>eccentric </u>
<u>
</u>Basing from the force-velocity curve, there are 2 muscle
actions, the concentric (shortening) and eccentric (lengthening). In eccentric
or lengthening muscle actions, force is high when the velocity is high. This is
opposite to concentric or shortening muscle actions, force is low when the
velocity is high. This means that in strength-gaining activities, the speed of
exercise should be slow during contraction, and it should be high when there is
expansion.
