Answer:
C
Explanation:
frequency = 1 / period
so
frequency = 0.25
0.25 = 1 / period
1 / 0.25 = period
4 s = period
it is not 4 Hz because period is the time taken
so the answer is C
hope this helps ,please mark it
The equivalent resistance of the two cylindrical conductors connected in parallel is 466 ohm.

Resistance</h3>
Resistance is a measure of the opposition to flow of electric current. It is measured in ohms.
It is given by the formula:

Given that R₂ = 469 ohm, hence:

But l₁ = 6l₂, r₁ = (1/5)r₂, hence:
![R_1=\rho \frac{l_1}{A_1}=\rho *\frac{6l_2}{[\pi (1/5)r_2]^2} =150 * \rho \frac{l_2}{[\pi r_2]^2}=30*469=70350\ ohm](https://tex.z-dn.net/?f=R_1%3D%5Crho%20%5Cfrac%7Bl_1%7D%7BA_1%7D%3D%5Crho%20%2A%5Cfrac%7B6l_2%7D%7B%5B%5Cpi%20%281%2F5%29r_2%5D%5E2%7D%20%3D150%20%2A%20%5Crho%20%5Cfrac%7Bl_2%7D%7B%5B%5Cpi%20r_2%5D%5E2%7D%3D30%2A469%3D70350%5C%20ohm)

The answer is
A) 1.3 x 10-7
Answer:
|A| = √(Ax)^2 + (Ay)^2
|A| = √(7.6)^2 + (-6.4)^2
|A| = √98.72
|A| = 9.9
The hotter molecules become, the faster they move around. The colder they are, the more slow and lethargic they are
