Answer:

Explanation:

Using the right-hand rule, the correct answer is:

A) Magnetic field

B) Electric current

C) Force

The equation corresponding to this graphical representation is

F = IBL

where I is the current, B the magnetic field, L the length of the wire and F the magnetic force.

You have a stopped pipe of adjustable length close to a taut 62.0-cm, 7.25-g wire under a tension of 3910 N . You want to adjust
Ber [7]

Answer:

L = 6 cm

Explanation:

Second overtone of the wire is same as third harmonic

so its frequency is given as

f = \frac{3}{2L}\sqrt{\frac{T}{\mu}}

here we know that

\mu = \frac{M}{L}

\mu = \frac{7.25 \times 10^{-3}}{0.62}

\mu = 0.0117 kg/m

now we have

f = \frac{3}{2\times 0.62}\sqrt{\frac{3910}{0.0117}}

f = 1398.6 Hz

Now fundamental frequency of sound in a pipe is given as

f = \frac{v}{4L}

1398.6 = \frac{340}{4L}

L = 0.06 m

L = 6 cm

A race car, traveling at constant speed, makes one lap around a circular track of radius 200 m. When the car has traveled halfwa
mario62 [17]

The magnitude of the displacement of the car from the starting point to halfway around the track is 256 m.

Answer:

Explanation:

Since the race track is a circular track, the distance for one lap will be equal to the circumference of the circular track. And the circumference will be equal to the circumference of the circle.

Since the radius of the track is given as 200 m, then the circumference of the circular track will be

Circumference = 2πr = 2 × 3.14 × 200

So the circumference of the circular track = 1256 m.

So the starting point or position of the track is considered as zero and if the car has traveled half way means, the car has covered half of the circumference of the track.

As the circumference = 1256 m, then half of the circumference of the circle = 1256/2 = 256 m.

So the displacement is the measure of difference between the final position and initial position. As here the initial position is zero and the final position is the halfway around the track which is equal to 256 m.

Then Displacement = Final-Initial = 256-0= 256 m.

So the magnitude of the displacement of the car from the starting point to halfway around the track is 256 m.
