in 1965, two scientists made a surprising discovery. they detected a faint microwave radiation signal coming from all over the universe
what is this microwave radiation?i’ll give brainlist

Answers

Answer: someone took down my answer I don’t know why when I took this test and got it right but the answer is C like the other person said.

Explanation:

The microwave radiation referred to in this context is radiation that was released as matter formed in the early universe. Therefore option A is correct.

Microwave radiation, also known as cosmic microwave background radiation (CMB), is a faint radiation that permeates throughout the universe.

It is considered to be the remnants of the thermal radiation released shortly after the Big Bang, during a phase called recombination. At this time, the universe transitioned from a hot, dense plasma to a state where neutral atoms could form, allowing photons to travel freely.

The cosmic microwave background radiation is isotropic, meaning it is uniformly distributed in all directions, and it has a characteristic temperature of approximately 2.7 Kelvin (-270.45 degrees Celsius).

It was first detected in 1965 by Arno Penzias and Robert Wilson, who were awarded the Nobel Prize in Physics for their discovery.

The presence of cosmic microwave background radiation provides strong evidence for the Big Bang theory and helps to support the understanding of the early universe's formation and evolution.

It serves as an important tool for studying cosmology and provides insights into the structure, age, and composition of the universe.

A 3.0 g bullet traveling at a speed of 400 m/s enters a tree and exits the other side with a speed of 200 m/s. Where did the bullet's lost KE go, and what was the energy transferred?

Answers

Answer:

1800J

Explanation:

Step one:

given data

mass of bullet m= 3g= 0.03kg

initial velocity u = 400m/s

final velocity v= 200 m/s

Step two:

1.The bullet's lost kinetic energy went inside the tree.

2. The energy transferred is computed as

= initial KE- KE final

Initial KE= 1/2mu^2

Initial KE= 1/2*0.03*400^2

Initial KE= 1/2*0.03*160000

Initial KE= 1/2*4800

Initial KE= 2400J

KE final= 1/2mv^2

KE final= 1/2*0.03*200^2

KE final= 1/2*0.03*40000

KE final= 1/2*1200

KE final= 600J

KE transferred = 2400-600

KE transferred= 1800J

Read the following case and discuss how you would respond to the situation.
PROBLEM:

You have been assigned the position of Environmental Engineer for one of several local
robotics manufacturers whose water discharges flow into a lake in a flourishing tourist area.
Although all the robotics companies in the area are marginally profitable, they compete for
the same customers. Included in your responsibilities is the monitoring of water and air
discharges
at your plant and the periodic preparation of reports to be submitted to the Department of
Natural Resources. You have just prepared a report that indicates that the
level of pollution in the plant's water discharges slightly exceeds the legal limitations. Your
boss, the Plant Manager, says you should regard the excess as a mere
"technicality," and he asks you to "adjust" the data so that the plant appears to be in
compliance. He says that the slight excess is not going to endanger human or fish
life any more than if the plant were in compliance. On the other hand, he says, solving the
problem would require a very heavy investment in new equipment. He
explains, "We can't afford new equipment. It might even cost a few jobs. It will set us
behind our competitors. Besides the bad publicity we'd get, it might scare off
some of the tourist industry, making it worse for everybody."

1) How do you think you should respond to your boss's request? Explain :

2) Define the problem :

3) what are the possible results of decision?

4) is there any information about the situation that is not obvious or available in the paragraph?

Answers

Explanation:

Hooke's Law: Fe = kx

x = Fe / k = (22.0N) / (4.00N/cm) = 5.50cm.

The new length of the spring is 15.50cm.

What conclusion can you draw from the information shown in the graph?
O A. Global temperatures are increasing due to human activity.
B. Earth is currently experiencing a period of global warming.
O C. Temperature is the only aspect of climate that is changing.
O D. Global temperatures are increasing due to natural causes.

Answers

Answer:

The correct option is;

B. Earth is currently experiencing a period of global warming

Explanation:

From the graph, we have;

1) From 1880 to 1900 the temperature anomaly (°C) averages a few degrees below the average surface temperature

2) The decrease below the average surface temperature is larger from  1900 to 1920

3) The surface temperature rises more steadily from below average to a little above average from 1920 to 1940

4) Between 1940 to 1980, the temperature hovers around the average surface temperature

5) The Earth's surface temperature is more or less steadily increasing from 1960 to present

Therefore, the Earth is experiencing a period of global warming

A man standing on top of a 30 m tall building throws a brick downwards with a velocity of 12 m/s. Determine the speed of the brick just before it hits the ground.

Answers

Answer:

27.1m/s

Explanation:

Given parameters:

Height of the building  = 30m

Initial velocity  = 12m/s

Unknown:

Final velocity  = ?

Solution:

We apply one of the kinematics equation to solve this problem:

         v²  = u²  + 2gh

v is the final velocity

u is the initial velocity

g is the acceleration due to gravity

h is the height

          v²   = 12²  + (2 x 9.8 x 30)

          v  = 27.1m/s

6. In baseball, a fastball takes about 1/2 second to reach the plate. Assuming that such a pitch is thrown horizontally, compare the distance the ball falls in the first 1/4 second with the distance it falls in the second 1/4 second.

Answers

Answer:

The ball falls 0.3 m in the first 1/4 seconds, and it falls 0.92 m in the second 1/4 second

Explanation:

Horizontal Launch

When an object is thrown horizontally with a speed v from a height h, it describes a curved path ruled exclusively by gravity until it eventually hits the ground.

To calculate the vertical distance (y) traveled by the object in terms of the time (t) we use:

[tex]\displaystyle y=\frac{g.t^2}{2}[/tex]

The fastball is thrown horizontally. The distance the ball falls in t=1/4 seconds = 0.25 seconds, is:

[tex]\displaystyle y_1=\frac{9.8*0.25^2}{2}[/tex]

[tex]\displaystyle y_1=0.30625\ m[/tex]

The distance the ball falls in t=1/2 seconds = 0.5 seconds is:

[tex]\displaystyle y_2=\frac{9.8*0.5^2}{2}[/tex]

[tex]\displaystyle y_2=1.225\ m[/tex]

The distance it falls in the second 1/4 second is:

[tex]y_2-y_1=1.225\ m-0.30625\ m[/tex]

[tex]y_2-y_1=0.91875\ m[/tex]

The ball falls 0.3 m in the first 1/4 seconds, and it falls 0.92 m in the second 1/4 second

D) conduction
E) none of the above

Answers

Answer:

i think a

Explanation:

Shuffling your feet across the floor as you walk is an example of charging by friction. The correct option is A.

What is friction?

The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction.

There are various kinds of friction: Two solid surfaces in touch are opposed to one another's relative lateral motion by dry friction.

Frictional force is the force produced when two surfaces slide against and touch each other.

The surface texture and amount of force needing them together have the biggest an impact on these forces. The amount of frictional force is influenced by the object's position and angle.

As an illustration of how charge is transferred via friction, consider walking over a carpet.

Thus, the correct option is A.
