Answer:

The Celestial Sphere

Explanation:

No matter where you are on Earth, stars appear to rotate about a point called the celestial pole.

Here's how it works:

Rotation of Earth: The Earth rotates on its axis from west to east. This rotation takes approximately 24 hours to complete one full rotation.

Celestial Poles: The celestial poles are imaginary points in the sky directly above the Earth's geographic poles. The North Celestial Pole is located directly above the Earth's North Pole, and the South Celestial Pole is located directly above the Earth's South Pole.

Apparent Motion: As the Earth rotates, the stars that are closer to the celestial poles appear to move in small circles around these poles. The stars that are farther away from the poles will have larger apparent circles.

Constellations and Circumpolar Stars: The constellations located near the celestial poles are known as circumpolar constellations. This means that they never fully set below the horizon from a specific location on Earth.

Equator and Horizon: The stars that are situated near the celestial equator (an imaginary line that's an extension of Earth's equator into the sky) will rise in the east, arc across the sky, and set in the west, much like the Sun does.

a)The analog signal's pitch and frequency change each time. It is continuous in the digital signal.

A digital signal is one in which data is represented as a series of discrete numbers.

To reduce the influence of noise in communication, a digital signal is utilized. When compared to analog signals, digital signals convey more information per unit of time.

a)Evelyn would most likely notice a difference between the two recordings after hearing them 100 times is that the analog signal's pitch and frequency change each time. It is continuous in the digital signal.

b)After 100 replays, the two recordings would sound different since the digital signal has a greater quality throughout long-distance transmission.

When digital signals are transferred, the amount of bandwidth used is lowered.

Hence, the digital signal has a greater quality throughout long-distance transmission causing two recordings would sound different.

Answer:

Slope y2-y1/x2-x1

m=mass/volume

slope represents density(g/ml)

Explanation:

PLS MARK BRAINLIEST

Slope = Mass/ Volume = Density. The given slope represents Density.

Thus, Density is the mass of a material substance per unit volume. d = M/V, where d is density, M is mass, and V is volume, is the formula for density.

Grams per cubic centimeter are a typical unit of measurement for density.  For instance, air weighs 1.2 pounds per cubic metre. In textbooks and manuals, the densities of typical solids, liquids, and gases are stated.

The volume of a body is equal to the mass multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d). Density provides a straightforward way to determine a body's mass from its volume, or vice versa.

Thus, Slope = Mass/ Volume = Density. The given slope represents Density.

Answer:

Below

Explanation:

Here is what newton's first law states :

     " An object will remain in straight line motion due to inertia unless acted on by an external force"

If you've ever been on a roller coaster you would know that when you go over the top of the roller coaster you feel lighter or feel like you are being lifted out of your seat. This is due to the effect of interia! Because the roller coaster car is a mass, it wants to continue in the direction it is traveling. If the roller coaster is going up the hill, the acceleration of the coaster wants to keep pushing you up. However, when the coaster goes over the hill, the force of gravity is pulling you down. The track forces the coaster to go down, and gravity is the force that is pulling it down. This is the force that changes the object's motion.

In which direction does the current in circuit A flow?

counterclockwise

Explanation:

The current flowing through the circuit A is [tex]I = \frac{e}{r_1 + r_2}[/tex].

"Your question is not complete, it seems to be missing the following information",

Answer: sum of the electric field energy density and magnetic field energy density.

Explanation:

The total energy stored in an electromagnetic wave is equal to the sum of energy stored in the electric and magnetic fields. In that case, the energy stored per unit volume, or energy density of the electromagnetic wave, is the sum of the electric field energy density and magnetic field energy density.

Hi there!

This collision is an example of an inelastic collision since kinetic energy is lost from the collision.

We can represent this using the conservation of momentum formula:

m1v1 + m2v1 = m1vf + m2vf

Where:

m1 = blue ball

m2 = green ball

We know that the final velocity of the blue ball is 0, so:

m1v1 + m2v1 = m2vf

Rearrange to solve for the speed of the green ball:

(m1v1 + m2v1)/m2 = vf

Plug in given values:

((0.15 · 3) + (0.15 · 2)) / 0.15 = 5 m/s

Using thermodynamics

The heat coming from the sun warms the land more quickly than the sea. As a result of these, the air near the land warm up and rises and the cooler air from the sea moves in to replace the risen air. The correct answer is option A

There will be heat transfer from a region of higher temperature to the region of lower temperature. But in the case of land and sea breeze, the transfer of heat are the result of convectional current in nature. Because the land is a better absorber of heat and also has a lower specific heat capacity compare to sea, during the day, the heat coming from the sun warms the land more quickly than the sea. As a result of these, the air near the land warm up and rises.

The cooler air from the sea moves in to replace the risen air.

Why do ocean winds or sea breezes blow toward shore during the day ? It is because air over the beach heats up, rises and is replaced by ocean air.

Therefore, option A is correct
