The diffraction causes "Light from the Sun reflecting off the moon bends around particles in Earth’s atmosphere and then spreads out."
What is diffraction ?Diffraction is a phenomena in which light bends around the corners of obstacle in its path. This happens when the size of the obstacle is comparable to the wavelength of the light.
What is light?Light, often known as visible light, is electromagnetic radiation that falls within the region of the electromagnetic spectrum which the human eye can perceive.
What is moon?Moon can be considered as natural satellite. Moon does not have its own light. It reflects the sun-light which is received by us. The light after reflection from the surface of the moon passes through the atmosphere of Earth wherein it gets scattered by the molecules of the gases present in the earths atmosphere. This gives a fuzzy glow around a full moon.

Charles Darwin used fossils as evidence to develop his theory of natural selection. Which event would most likely lead to a change in this theory?
Answer:
Darwin used fossils as pieces of evidence in order to develop the theory of natural selection.
He observed that the fossils of simple organisms are found to be present in much older rocks, whereas fossils of more complex organisms are obtained from the geologically younger rocks. This observation of fossils made him understand how the evolutionary process takes place in due course of time. This evolution takes place due to the natural selection method, where an organism is adapted to a particularly suitable environment.
Thus, the discoveries of various fossils helped in developing the natural selection theory.

tthinks that mr. Bianchi was going much faster. After the collision the two cars got stuck and from the tracks on the asphalt it was possible to establish that, immediately after the collision, they were traveling at 30 km / h. Mr. Bianchi drove a car with a mass of 800 kg and Rossi a car with a mass of 1400 kg.

1. A car travels along a straight road to the east for 100 meters in 4 seconds, then go the west for 50 meters in 1 second.
find the
a. Distance
b. Displacement
c. Time elapsed
Answer:
a.Distance = 150 m
b. Displacement = 50 m
Time lapsed = 5 seconds
Explanation:
a. Distance is the change in the position of an object.
The distance covered by the car = 100 + 50
= 150 m
b. Since displacement is a vector quantity,
Displacement of the car = 100 - 50
= 50 m due east
c. Time elapsed is the time taken for the motion of the car starting from when its starts to when it stops.
Thus, the time elapsed = 4 + 1
= 5 seconds

At which location does a skateboarder have the most kinetic energy at least potential energy?
Answer:The skater has the lowest amount of kinetic energy at the top of the track and lowest potential energy at the lowest point of the track. Kinetic energy is the speed a object is going, and potential energy is the energy a object has when its not moving. While the skater moves up the ramp the potential energy increases, and the kinetic energy decreases because it slows down while moving up the ramp. Hope this helps have a nice day ❤️
Explanation:
First recognize that the total energy of the skater is conserved: this means that the total energy of the skater is constant. The total energy (E) consists of the kinetic energy (KE) and gravitational potential energy (Ug).
E=KE+Ug
Now we know that the gravitational potential energy depends on the distance from the zero of potential (or in simpler terms: how high the skater is from the ground). Now, we are ready to answer the question.
The skater possesses the most KE at point B: remember total energy is a constant and at point B the skater has the least amount of potential energy (since they are at their lowest point above the ground). This means that the skater must have more kinetic energy at point B.
Similarly, at points A and C, the skater possesses the most potential energy since they are at their highest point above the ground.
As the skateboarder moves then it will have the maximum kinetic energy at the lower most portion of the track and will have the zero potential energy at the same point and at the maximum height of the track the skater will have maximum potential energy and zero kinetic energy.
What will be the KE and PE of the skater at maximum and minimum positions of the track?As the skater moves on the track his kinetic and potential energy converts into each other but the total energy remains constant.
Total Energy = KE+PE
At maximum height the kinetic energy will totally convert into the potential energy and becomes zero.and the potential energy becomes maximum at this point.
At Max height (Total energy=Max Potential energy) KE=0
Similarly at the lower most portion of the track the Potential energy completely convert into the kinetic energy and becomes zero. And kinetic energy becomes max at this point.
At lower point (Total energy= Max Kinetic Energy) PE=0
Thus the skater will have the most kinetic energy at the lower most point of the track and least potential energy at the same point.

And air rifle pellet of mass 2 g Is fired into a block of modelling clay mounted on a model railway track. The trunk and modelling clay have a mass of 0.1 kg the truck moves off after the pellet hits the modelling clay with an initial velocity of 0.8 m/s. State the momentum of the pallet just before it hits the modelling clay
Answer:
0.0816 kgm/s
Explanation:
From the question,
Momentum of the pellet just before it hits the modelling clay is = (mass of the pellet+ mass of the truck clay)×initial velocity of pellet.
P =(M+m)u...................... Equation 1
Where P = initial momentum of the pellet, m = mass of the pellet, u = initial speed of the pillet, M = mass of the truck
Given: m = 2 g = 2/1000 kg = 0.002 kg, u = 0.8 m/s, M = 0.1 kg
Substitute these values into equation 1
P = (0.002+0.1)0.8
P = (0.102)0.8
P = 0.0816 kgm/s

If the greenhouse effect is natural, then why is today's climate change a bad thing?
A.)A small increase in greenhouse gas concentration can have a large effect of increased warming.
B.)Humans have altered a natural process and exaggerated changes that might normally occur over millions of years.
C.)Once released into the atmosphere, greenhouse gases remain potent for many years, making it difficult to reverse the process.
D.)Abrupt changes to the climate system may have unintended outcomes that may pose challenges for societies, like more extreme weather, spread of diseases, a decline in marine life, or an alteration of ocean circulation patterns.
E.)All of these
Answer:
B.)Humans have altered a natural process and exaggerated changes that might normally occur over millions of years.
Explanation:
While the greenhouse effect is natural and in fact, helps maintain a climate suitable for life as we know it, humans have altered a natural process. A small change in the amount of greenhouse gases in the atmosphere has a large and long-lasting effect. Furthermore, humans have changed the composition of the atmosphere over a short time span, and the resulting warming us many times faster than natural changes. We are already seeing consequences like heat waves, melting sea ice, rising sea level, increased wildfires, and increases in extreme weather.

A body of mass 11 kg is subjected to a net force of 20 N East for 30 s. Calculate the change in
velocity of the body.
Answer:
54.55 m/s
Explanation:
From the question above,
Change in velocity = impulse/mass
Δv = I/m = Ft/m................... Equation 1
Where F = force, t = time, m = mass
Given: F = 20 N, t = 30 s, m = 11 kg
Substitute these values into equation 1
Δv = (20×30)/11
Δv = 600/11
Δv = 54.55 m/s
Hence the change in velocity of the body is 54.55 m/s
The change in velocity of the body is 54.54 m/s
The velocity of the body of an object is the change of the distance of the object with time.
From the information given:
the mass of the b0dy = 11 kg
the net force F = 20 N
the time (t) = 20 s
Similarly;
Force = ma
20 = 11 × (a)
[tex]\mathbf{a = \dfrac{20}{11} \ m/s^2}[/tex]
a = 1.818 m/s²
However, the acceleration of an object is the change in velocity with time.
[tex]\mathbf{a = \dfrac{\Delta V}{t}}[/tex]
ΔV = (a) × (t)
ΔV = 1.818 m/s² × 30 s
ΔV = 54.54 m/s
