Answer:

The discovery that one current-carrying wire exerts a force on a second current-carrying wire was made by <u>Ampere</u>

Explanation:

Two current carrying wires exert force on each other. This was discovered by Ampere. It is also known as Ampere's force law.

A current carrying wire produces magnetic field around it. Another current carrying wire kept nearby experiences magnetic force by the first one.

The force is given by:

F= \frac{\mu _o}{2\pi} \frac{I_1I_2}{r}l

where I₁ and I₂ are the currents in the two wires and r is the distance between them.

The force may be attractive or repulsive depending upon the direction of current flowing in the two wires.

A wave travels at a frequency of 387 Hz. What is<br>the period of the wave?<br>​
Ulleksa [173]

Answer:

¹/₃₈₇ second

Explanation:

<em>The period of a wave is the reciprocal of its frequency.</em>

So, simply, the frequency is ¹/₃₈₇ second(s), as that is the reciprocal of the frequency, 387 Hz.

The four tires of an automobile are inflated to a gauge pressure of 2.2 105 Pa. Each tire has an area of 0.023 m2 in contact wit
Stels [109]

Answer:

Force, F = 20240 N

Explanation:

It is given that,

Pressure exerted by the four tires of an automobile, P=2.2\times 10^5\ Pa

Area of each tire, A=0.023\ m^2

Area of 4 tires,  A=0.092\ m^2

We know that the pressure exerted by an object is equal to the force per unit area. Its formula is given by :

P=\dfrac{F}{A}

F=P\times A

F=2.2\times 10^5\times 0.092

F = 20240 N

So, the weight of the automobile is 20240 N. Hence, this is the required solution.
