Digital information can be sent through the vacuum if space, but the information must be converted to wave pulses. The correct option is B.

<h3>What is digital information?</h3>

The digital information consists of data generated by the electrical systems. For examples, computers, screens, scientific calculators or any communication devices.

The electromagnetic waves do not require medium, So, they can travel through vacuum. So, Digital information can be sent through the vacuum or space.

Therefore, the correct option is B.

Which is the one factor that adds to the greenhouse effect? 1. a decrease in the amount of dust in the atmosphere 2. a decrease
lukranit [14]

Answer:

an increase in gasses that absorb heat

Explanation:

Greenhouse effect refers to the gradual increase in the earth's temperature due to an increase in the concentration of certain gases in the atmosphere. These gases are called greenhouse gases and they include; water vapour, nitrogen 1 oxide, carbon IV oxide etc. Green house effect is said to occur when heat radiating outwards from the earth surface towards space is trapped close to the earth's surface due to the presence of greenhouse gases in the atmosphere.

Greenhouse effect leads to increase in the temperature of the earth, melting of polar ice caps and possibly flooding due to a rise in sea levels.

Greenhouse gases act as glass in a greenhouse. They allow heat to pass through onto the earth surface but trap the heat and prevent it from being radiated outwards back to space. Thereby increasing the surface temperature of the earth.

A bus hits a bug and the bug splatters on the windshield, which force is greater?
grandymaker [24]

The forces acting on a body and the type of motion that results are given by Newton's three Laws of motion

  • The <u>force </u>of the bus is <u>the same</u> as reactive force of the bug

Reason:

According to Newton's third Law of motion, given that the bug collides

with the bus, the force with which the bus hits the bug is equal to the

reactive force of the bug on the on the bus

According to Newton's second Law of motion, force is equal to the rate of

change of the momentum produced

The impulse of the force of the bus on the bug is given as follows;

F·Δt = m·(v₂ - v₁)

Given that the force of the bus is large, the change in momentum, m·(v₂ - v₁),

is also large such that the parts of the bug are split by the rapid change in

velocity, and the bug splatters on the windshield, and is then carried along

on the trip,

The equally large reactive force of the bug, is such that the bug splatters

due its magnitude

Therefore, the correct response is that <u>the forces are the same</u>

A light ray traveling from a higher index of refraction medium into a lower index of refraction medium (for example, from water
masya89 [10]

Answer:

option C

Explanation:

The correct answer is option C

When the ray of light pass from higher refractive index to lower refractive index then the light bend  away from the normal.

when the refracted ray is parallel to the boundary of the medium, θ₂ = 90°

and the incident angle θ₁

so, the angle  θc is known as the critical angle.

At critical angle the refracted ray becomes parallel to boundary surface.
