Answer:

A compass works by detecting and responding to the Earth's natural magnetic fields. The Earth has an iron core that is part liquid and part solid crystal, due to gravitational pressure. It is believed that movement in the liquid outer core is what produces the Earth's magnetic field.

Answer:

The natural magnetic fields of the Earth are detected and responded to by a compass. Due to gravitational pressure, the Earth's iron core is partially liquid and partly crystallized. The Earth's magnetic field is thought to be created by movement in the liquid outer core. The Earth's magnetic field, like all other fields, has two poles: north and south. However, even though the geographic and magnetic poles are slightly offset from one another, the compass can still be an extremely useful tool for navigation, especially when declination is taken into account to account for the slight polar differences.

I hope this helps you

Fundamental frequency,

=(50)/0.1×10−3/10−22×0.6−−−−−−−−−−−−−−−−−−−√

=58.96Hz

Let, n th harmonic is the hightest frequency, then

(58.93)n = 20000

∴N=339.38

Hence, 339 is the highest frequency.

∴fmax=(339)(58.93)Hz=19977Hz.

<h3>What is frequency?</h3>

In physics, frequency is the number of waves that pass a given point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time. After moving through a sequence of situations or locations and then returning to its initial position, a body in periodic motion is said to have experienced one cycle or one vibration. See also simple harmonic motion and angular velocity.

Reflected light from a thin film of oil gives constructive interference for light with a wavelength inside the film of λfilm. By

My name is Ann [436]

Answer:D. λfilm/4

Explanation: Destructive interference is a type of wave interference which means the coming together or over-lapping of two opposing waves creating No effect or the Cancellation of the wave impact. An example of destructive wave is when Noise cancel the effect of sound from a head phone.

The film thickness will need to be increased by λfilm/4 for it to be able to give a destructive interference.

A bullet leaves a gun with a horizontal velocity of 100 m/s. Calculate the distance it would travel in 1.3 seconds.

salantis [7]

Answer:

130m

Explanation:

You just have to multiply velocity by the time traveled:

100m/s * 1.3s = 130m!

a conducting rod whose length is 25 cm is placed on a u-shaped metal wire that has a resistance of 8.0 ω . the wire and the rod

andreyandreev [35.5K]

Answer:

The current is $I = 1 A$

The direction is anti-clockwise

Explanation:

The diagram for this question is shown on the first uploaded image

From the question we are told that

the length of the conducting rod is $L = 25 \ cm = \frac{25}{100} = 2.5 \ m$

The resistance is $R = 8 \Omega$

The magnetic field is $B = 0.40\ T$

The speed of the rod is $v = 6.0 m/s$

The emf induced is

$\epsilon = BLv$

substituting values we have

$\epsilon = 0.40 * 2.5 * 8$

$\epsilon = 8V$

From ohm law the induced current would be

$I = \frac{\epsilon}{R }$

substituting values we have

$I = \frac{8}{8 }$

$I = 1 A$

The direction anticlockwise this because according to lenze law the current due to change in magnetic field will act in the opposite direction of the force causing the magnetic field to change

Select the correct answer. The motion of a car on a position-time graph is represented with a horizontal line. What does this in

enyata [817]

If the car's motion appears as a horizontal line on a position-time graph, it shows that as time changes, the car's position doesn't change.

This is just a complicated way to say that the car is not moving. (A)
