Give reasons.
a) Sunlight does not fall on the ground where cloud forms shadow.​

Answers

Answer 1

Answer:

Sunlight passing through a cloud is scattered in various directions. Some photons eventually find their way out the bottom of the cloud, some are reflected upwards, and some are absorbed, serving to warm the cloud. Since only a fraction of the light makes it to ground level, you have a shadow.

The speed of electromagnetic waves in a vacuum __________. The speed of electromagnetic waves in a vacuum __________. is larger for longer wavelengths is the same for all waves regardless of wavelength is the same as the speed of sound is larger for higher energies

Answers

Answer:

is the same for all waves regardless of wavelength

Explanation:

Electromagnetic waves are often collectively called light. Light has become a generic name that is applied to all electromagnetic waves. The arrangement of electromagnetic waves according to their respective wavelengths is called the electromagnetic spectrum.

When passing through a vacuum, all electromagnetic waves irrespective of their individual wavelengths must possess the same speed. This is called the speed of light in a vacuum. The speed of light in a given medium is a constant and applies to all electromagnetic waves irrespective of their frequency and wavelength.

Which image below represents the electric field lines between two positively charged particles? (2 points)

A positive particle sits in the center of a dotted circle. There is a negative particle along the dotted circle.

Two particles sit side by side. There are curved field lines that point from one particle to the other in a counter clockwise direction above the particles and a clockwise direction below the particles.

Two particles sit side by side. There are curved field lines that point away from each particle. The particle on the right has field lines pointing to the right. The particle on the left has field lines pointing to the left.

One particle sits in the center of curved field lines that extend beyond the particle then return to the particle. Arrows along the curved field lines point in a clockwise direction above the particle and a counter clockwise direction below the particle.

Answers

The electric field is defined as the aura of electrons in which it exerts force and attracts the negetivily charged particles.

The electric field line depends on the following:-

The magnitude of the electrons.

The correct option is as C.

The flow of the electric field line is from Positive to negative and it always attracts the negative particle. The alike particles attract each other while the like particles are repealed each other.

Hence the correct option is C that is two particles sitting side by side. There are curved field lines that point away from each particle. The particle on the right has field lines pointing to the right. The particle on the left has field lines pointing to the left.

Mark conducts a study for his research methods class to determine if consuming caffeine causes people to perform better on cognitive tasks. In his study, he gives half of his participants a glass of water and half of his participants a glass of cola, and then has them attempt to solve 15 math problems. He finds that people who drink caffeine beforehand solve more math problems than those who drink water beforehand. Mark decides to conduct a variation of the original study in which he measures participants' ability to solve verbal analogies as the cognitive task instead of measuring their ability to solve math problems. He finds that people who drink caffeine beforehand solve more verbal analogies than those who drink water beforehand, suggesting caffeine consumption causes improved cognitive performance.
