The type of evidence which supports this theory is C. volcanoes and igneous rocks found on the ocean floor.
Normally, these types of ruptures and stones don't appear in water, however, after being submerged in oceans for such a long time, today it is a normal occurrence.

A stationary charge is located between the poles of a horseshoe magnet. Is a magnetic force excerted of the charge? why?
vredina [299]

A stationary charge is located between the poles of a horseshoe magnet. The magnetic force exerted by the charge is zero.

<h3>What is charge?</h3>

Charge is the physical property of matter which cause a particle to attract or repel when placed in its field.

A stationary charged particle does not interact with a static magnetic field. A charge placed in a magnetic field experiences a magnetic force. There will be no magnetic force acting on a stationary charge. The charge must be moving in order to have magnetic force on it.

Thus, the magnetic force exerted by the charge is zero.

A proton, traveling with a velocity of 4.6 × 106 m/s due east, experiences a magnetic force that has a maximum magnitude of 6.0
Kobotan [32]

Answer:

B = 0.0815 T

since the direction of force is along south so the magnetic field must be upwards

Explanation:

Force on moving charge in magnetic field is given as

F = q(\vec v \times \vec B)

here we know this is force on proton

so we have

q = 1.6 \times 10^{-19} C

F = 6.0 \times 10^{-14} (-\hat j) N

also we know that the velocity of charge is

v = 4.6 \times 10^6 \hat i m/s

now from above formula we have

(6.0 \times 10^{-14}) = (1.6 \times 10^{-19})(4.6 \times 10^6)B

B = 0.0815 T

since the direction of force is along south so the magnetic field must be upwards

Explain briefly where the energy come from when a liquid Rises against Gravity in a capillary tube​
SSSSS [86.1K]

Answer:

Surface tension

Explanation:

When liquid rises against gravity in a capillary tube, the energy comes from surface tension.

This is because surface tension is the energy that's needed to increase the liquid surface area.

As a result of hydrogen bonding present in Water, it usually has high surface tension which makes it to possess a tough skin that can make it not to break despite high forces applied to it.

The liquid will be in contact with the capillary tube and as such experiences surface tension which in turn makes the capillary tube to experience an upward force that makes the liquid begin to rise up.

The more the liquid keeps rising, the more it gets to the point where the surface tension becomes balanced from the weight of the liquid.
