Explanation:
The given data is as follows.
Resistance (R) = 1200 ohm, Area (A) = m (as )
Diameter (d) = 2.3 mm = m
First, we will calculate the length as follows.
R =
Here, = resistivity of aluminium =
Putting the given values above and we will calculate the value of length as follows.
R =
1200 =
L =
As the circumference of circular wire =
or, =
=
And, number of turns will be calculated as follows.
No. of turns × Circumference = Length of wire
No. of turns ×
=
Thus, we can conclude that turns of wire are needed.
To simplify his insane equation, do M*G*H (Mass*Gravity*Height)
so like this.
2 (Mass)*9.8 (Gravity)*40 (height)
then when you multiply, you get
784 kg m^2/s
Answer:
139 N
