Answers

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.

If a truck starts from rest and it has acceleration of 4 m/s for 5 second calculate its final velocity. What will be the distance travelled by the truck during the time interval? ​

Answers

Answer:

20m/s final velocity, 60meters is the distance

Explanation:

since it accelerates 4m/s we can assume every second it goes up by 4 so we do 5×4=20...

while for the distance we have to think about the fact that every second the speed changes (precisely every second adding 4m/s) so in the first second its going to travel 4 meters in the second 8m in the third 12m in the fourth 16m and in the fifth 20m... so we just calculate them for addition and get 60 meters

What is the power dissipated by the resistor of resistance R2 for circuit A, given that E=10 V, R1=300ohms, and R2=5000ohms? Calculate the power to two significant figures.0.064WFor what ratio of R1 and R2 would power dissipated by the resistor of resistance R2 be the same for circuit A and circuit B?R1/R2 = 1 Under which of the following conditions would power dissipated by the resistance R2 in circuit A be bigger than that of circuit B? Some answer choices overlap; choose the most restrictive answer.R2>R1

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",

find the the current flowing through the resistors in circuit A;

Sammy feels an ocean breeze as he plays volleyball at the beach. Why do ocean winds or sea breezes blow toward shore during the day? Question 2 options: Air over the beach heats up, rises and is replaced by ocean air. Earth's rotation causes air to blow toward land. he energy of the ocean storms push air toward shore. Ocean air is less dense, so it rises to replace air over the land.

Answers

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.

In this graph (mass vs volume), what does the slope represent? I will mark brainliest​

Answers

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.

Evelyn learns that a sound wave can be recorded electronically as an analog signal or as a digital signal. She investigates these two signal types. She records her voice using a tape recorder, which uses an analog signal to produce sound when played back. She also records her voice using a computer, which uses a digital signal to produce sound when played back. Evelyn replays each recording 100 times.

a. Describe a difference that Evelyn would most likely hear between the two recordings after being replayed 100 times.

b. Explain why the two recordings would sound different after being replayed 100 times.

Answers

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

What is 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.

A tennis ball is tossed upward with a speed of 3.0 m/s. We can ignore air resistance.
What is the velocity of the ball 0.40 s after the toss?

Answers

Answer: Hello, The velocity of the ball is 0.92 m/s in the downward direction (-0.92 m/s).

Explanation: The equation for the velocity of an object thrown upward is the following:

v = v0 + g · t

Where:

v = velocity of the ball.

v0 = initial velocity.

g = acceleration due to gravity (-9.8 m/s² considering the upward direction as positive).

t = time.

To find the velocity of the ball at t = 0.40 s, we have to replace "t" by 0.40 s in the equation:

v = v0 + g · t

v = 3.0 m/s - 9.8 m/s² · 0.40 s

v = -0.92 m/s

The velocity of the ball is 0.92 m/s in the downward direction (-0.92 m/s).
