A mixture is a substance made by mixing other substances together.
We are asked in what manner can one make the motor run in reverse. One way to do so is to flip the magnet on the other side so that the opposite charge faces to the motor. The magnetic field induced by the magnet to the motor results to a reactive force opposite to the induced motion.
You first need to convert the hours into minutes, then use the speed equals distance over time formula.
Answer:
ρ = 1.70 Ωm
Explanation:
given data
diameter = 1.8 mm
distance = 4.8 cm
volt = 9 V
potential difference = 280
solution
we know that Resistance that is express as
Resistance =
..............1
V = I × R
and
V = I ×
..........2
put here value we get
9 = 280 ×
×
ρ = 1.70 Ωm
Answer:
Option C. 4 Hz
Explanation:
To know the correct answer to the question given above, it is important we know the definition of frequency.
Frequency can simply be defined as the number of complete oscillations or circles made in one second.
Considering the diagram given above, the wave passes through the medium over a period of one second.
Thus, we can obtain the frequency by simply counting the numbers of complete circles made during the period.
From the diagram given above,
The number of circles = 4
Thus,
The frequency is 4 Hz
