Answer:

A. no oxygen.

E. presence of inorganic molecules.

F. high levels of ultraviolet radiation.

Explanation:

These are most likely the conditions on meteorites in space that are similar to those that likely prevailed on Earth in its early history. We know that in the early history of the Earth, oxygen, which is vital for life on Earth nowadays, was not present in the ways it is now. We also know that inorganic molecules have been present since the beginning of the planet. Finally, the planet also had high levels of ultraviolet radiation.

A proton experiences a force of 4 Newton when it enters perpendicular to the direction of the magnetic field with a speed 100 m/

____ [38]

Answer:

F = 0 N

Explanation:

Force on a moving charge in constant magnetic field is given by the formula

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

so here it depends on the speed of charge, magnetic field and the angle between velocity of charge and the magnetic field

here when charge is moving with speed 100 m/s in a given magnetic field then the force on the charge is given as

$F = 4 N$

now when charge is moving parallel to the magnetic field with different speed then in that case

$\vec v \time \vec B = 0$

so here we have

F = 0

How does upwelling affect the weather of a coastal region?

SIZIF [17.4K]

c.The warm surface water results in moist air and more rainfall.

Explanation:

During upwelling, cold water in the ocean is stirred up and brought to the surface.
The warmer surface water is then taken into deeper parts of the ocean.
Upwelling allows for nutrient mixing in the ocean and allows for useful gases to circulate well.
The warm surface water causes the air to be moisty.
When the air is carried landward towards the coast, it leads to rainfall when the saturated air releases the water.
The air then becomes cold and dry and it rises up.
Therefore, warm surface water results in moist air and more rainfall.

The radiation detector that uses detection of flashes of light is a _____

Maslowich

The radiation detector that uses detection of flashes of light is a <u>scintillation counter.</u>

<h3>What is a scintillation counter?</h3>

A scintillation counter detects and measures ionizing radiation by using the excitation action of incoming radiation on a scintillating substance and detecting the light pulses that arise.

One of the most critical considerations for anyone who operate with or near radiation is being aware of the amounts of radiation present.

This is generally performed through the use of several types of radiation detectors.

The radiation detector that uses detection of flashes of light is a scintillation counter.

Hence,scintillation counter is the correct answer.
