What is thermal pollution?

The theory of evolution is that organisms evolve over time.

Light is created by vibrations in electric and magnetic fields because the light is an electromagnetic wave, therefore the correct answer is option C

What is an electromagnetic wave?

The oscillation of an electric field and a magnetic field produces electromagnetic waves, which are waves. In other words, electromagnetic waves (EM waves) are made up of vibrating magnetic and electric fields that are orthogonal to one another.

It is undeniable that we experience solar radiation, which is an electromagnetic wave that originates from the sun and can travel through space to the planet.

Light is a form of electromagnetic which is made up of the electric and magnetic filed that are orthogonal to each other, light can travel without any medium.

Thus, Light is created by vibrations in electric and magnetic fields, because the light is an electromagnetic wave, therefore the correct answer is option C

Answer:

b

Explanation:

light does not need a medium

it is refracted

Light is made up of little packets of energy called photons.

electromagnetic waves

Answer:

Neglecting, air resistance, friction and breaking, all the condition has conservation of mechanical energy.

Explanation:

• The law of conservation of mechanical energy suggests that the mechanical energy in a locked system with out any destructive forces like friction or air resistance remains always the same (constant).
• The energy may be converted between kinetic energy, potential energy, gravitational potential but energy do not get decreased in any cases as mentioned in the option.
• So all the cases mentioned above shows the conservation pattern of mechanical energy.

Answer:

D)  the sound of the explosion would not be transmitted back to their ship.

Explanation:

Sound is a mechanical wave. A mechanical wave requires a medium to travel and transfer energy. It travels be compression and rarefaction of the medium. Since in space it is vacuum, the sound energy by the explosion of the spaceship would not be able to travel through the space, the Klingon crew are not required to cover their ears to muffle the noise. This scene would be inaccurate scientifically.

Answer;

The above statement is False

Explanation;

• Saturated fats are types of fats that lacks double bonds or triple bonds between any two carbon atoms because they are saturated with hydrogen molecules.
• Saturated fats should be limited at all costs. Eating foods with saturated fats raises the amount of cholesterol in the blood which may increase the risk of heart disease and stroke.
• Avocados contain over 75% fat that is unsaturated or the good fats, and the rest are unsaturated or the bad fats. Therefore, saturated fats found in avocados are not good and should be limited.
