The resistance of the coil is 12. 97 Ω

<h3>How to determine the length</h3>

The formula for resistance is given as;

R = V/I

Note that resistance, R is measured in Ohms and represented with the symbol ( Ω)

Where;

  • V is the voltage = 120 V
  • I is the current = 9. 25 A

Substitute the values into  the formula

R = 120/ 9. 25

R = 12. 97 Ω

The resistance, R is 12. 97 Ω

Hence, the resistance of the coil is 12. 97 Ω

kykrilka [37]
The force depends on the mass of both objects and the distance between them

F = G*m1*m2/r^2

So the force has a linear connection with the mass of both objects and a quadratic connection with the distance between the center of masses

Which statements describe both male and female reproductive systems? Check all that apply. A:The reproductive system produces ho
Scilla [17]

Answer: A:The reproductive system produces hormones.

B:The reproductive system transports reproductive cells.

C:The reproductive system produces reproductive cells.

Explanation:

A:The reproductive system produces hormones. : The reproductive organs ovaries in females and testes in males produces hormones. The ovaries produce estrogen and progesterone and testes produce testosterone.

B:The reproductive system transports reproductive cells. : The ovaries in females transfers an egg into the fallopian tube and testes in males secrete sperms at the time of copulation the fertilization of egg and sperm leads to the development of zygote the precursor of new life.

C:The reproductive system produces reproductive cells.: The ovaries undergo oogenesis and in testes spermatogenesis takes place to develop egg and sperms respectively.
