Answer:

Since electromagnet waves do not need a medium they can travel through space. Sound waves can't travel through space because they need a medium.

Explanation:

The satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.

The types of electromagnetic waves that are used by satellites are known as radio waves. These waves are utilized in order to carry out satellite signals with a speed of 3000,000km/sec.

Electromagnetic waves facilitate the required amount of speed and characteristics which ease the transmission of information required by the satellites. Radio waves are traveling through the vacuum of space with the fastest speed at which the information via the satellite can be transmitted. Radiowaves are also used for spacecraft communications as well.

Therefore, the satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.

Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.

Answer:

Time, t = 9.62 secs.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex] ....equation 1

Making time the subject formula;

[tex]Time = \frac{distance}{speed}[/tex] .....equation 2

Given the following data;

Distance = 100m

Speed = 10.4m/s

Substituting into equation 2;

[tex]Time = \frac{100}{10.4}[/tex]

Time, t = 9.62 secs.

Explanation:

Answer:

Explanation:

Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes.

The climate change increases the overall temperature of the earth, glaciers can melt into the ocean. The spheres involved cryosphere and hydrosphere. Thus option A is correct.

Cryosphere is defined as solid precipitation, snow,  sea ice, lake and river ice, icebergs, glaciers and ice caps, ice sheets, ice shelves, , and seasonally frozen ground are all components of the Earth's climatic system.

It can also be defined as the area of the earth's surface marked by the presence of water.

Hydrosphere is defined as the total mass of water on, beneath, and above the surface of a planet, minor planet, or natural satellite.

It can also be defined as the component of the Earth made up of all liquid water.

There are basically three types of hydrosphere.

Climate change is defined as the long-term temperature and weather pattern shifts These changes could be natural, such as oscillations in the solar cycle.

Thus, the climate change increases the overall temperature of the earth, glaciers can melt into the ocean. The spheres involved cryosphere and hydrosphere. Thus option A is correct.
