Step 1: Look in your book or online for the conical pendulum equation.
Step 2: Look at the drawing and see which angle is involved in the equation.
Answer: It's Angle #2 in your drawing.
Answer:
the length of the wire is 134.62 m.
Explanation:
Given;
resistivity of the copper wire, ρ = 2.6 x 10⁻⁸ Ωm
cross-sectional area of the wire, A = 35 x 10⁻⁴ cm² = ( 35 x 10⁻⁴) x 10⁻⁴ m²
resistance of the wire, R = 10Ω
The length of the wire is calculated as follows;

Therefore, the length of the wire is 134.62 m.
Answer: C
Explanation: The correct answer would be Inertial. I take the quiz and got the answer rght!!
Is there any options or just a type up answer?
It would be: F = m.a = 90 * 1.2 = 108 Kgm/s² = 108 N
So, force of 108 Newtons is required for that..
