Answer:

Granules

Explanation:

The outer most layer of the Earth is photo-sphere. The photo-sphere layer of the sun is characterized by many bright markings i.e. it has a grainy texture. These are called granules. Granules are produced due to convection currents. The top of the convection cells are visible which give it a grainy texture and is known as granulation.

You observe a distant galaxy. You find that a spectral line, resulting from an electron transition in hydrogen, is shifted from
alexandr1967 [171]

Answer:

The galaxy is moving away from the observer

Explanation: when a galaxy is moving away from us, the light we percieve from it is "streched". Since the wavelength has an inverse raltionship whith frequency, the longer the wavelength is, the lower the frequency. And lower frequencies correspond to red and infrarred light.

So when we see the light has shifted to the infrarred part of the spectrum, it means the source is traveling away from us, making the light waves we percieve streched and move from visible light to infrarred.

What are three properties of electromagnetic waves?
Zolol [24]

The three properties of electromagnetic waves are; they travel at the speed of light, they include ultraviolet waves, and they can transfer energy through empty space.

<h2>Further Explanation</h2><h3>A wave</h3>
  • A wave is a transmission of a disturbance. It involves transmission of energy from one point which is the source to another point.
  • Waves may be classified depending on the need for a transmission medium or based on the vibration of particles relative to the direction of wave motion.
  • Waves may be either transverse or longitudinal based on the direction of wave motion relative to the vibration of particles
  • Additionally waves may be classified as either electromagnetic wave or mechanical based on the need for a transmission medium.
<h3>Electromagnetic waves  </h3>
  • Electromagnetic waves are types of waves that do not require a material medium for transmission.
  • All waves of the electromagnetic spectrum are electromagnetic transverse waves that do not require a material medium for transmission.
  • They include; radio waves, microwaves, infrared, visible light, ultra-violet, x-rays, and gamma rays.
  • All waves of the electromagnetic spectrum travel with a speed of light, 3.0 x10^8 m/s.
  • Additionally, electromagnetic waves possess energy that is given by; E = hf; where h is the plank's constant and f is the frequency.

Carrie is driving a car. Which factors determine the kinetic energy of her car<br> at this point
Valentin [98]

Answer:

The two main factors that affect kinetic energy are mass and speed.

Explanation:

Kinetic energy is the energy that is caused by the motion. The kinetic energy of an object is the energy or force that the object has due to its motion. Your moving vehicle has kinetic energy; as you increase your vehicle's speed, your vehicle's kinetic energy increases.

Have a great day! :D
