How can you explain why the sun appears to be moving through the sky during the day
Answer:From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles.

Will the net force be greater or lesser for objects with greater mass?
Answer:
The answer is
→ If an object has a greater mass, then the net force will be lesser.
Explanation:
The net force will be lesser because the greater mass the object is, the slower the net force will be.
If we were to talk about lesser mass in an object, then the net force will be faster, but this isn't the case right now.

Answer:
hi,human absorb 0oxygen =aborption ,reflection =the light that entered in the water,refraction =the light that pass outside the water
Explanation:
Answer:
Refraction = The divers head looks detached from his body.
Absorption = Some of the colours are being absorbed making the snorkel look yellow/greenish.
Reflection = The reflection of the sun, sky, sound and light.
Transmission = Light entering the water.

an object appears fuzzy when seen though an ___________ material.
if u get it right u get brainliest
Answer: A part of the incident light may get reflected or scattered, as it passes through the interior of the material. Any object, seen through a translucent material, appears fuzzy or blurred. Some examples are oily paper, tissue, some plastics, etc. [Image will be Uploaded Soon]
Explanation:
Answer:
Wax paper and frosted glass are translucent materials.
Explanation:
You can usually see something behind a translucent object, but the details are blurred.

Explain constant and changing velocity.
Answer:
To summarize, an object moving in a uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.
Answer:
In order for the velocity to be constant, the magnitude of the velocity (or speed) and the direction of the velocity must not change. Therefore, an object that travels with constant velocity covers the same distance during each time interval and moves in the same direction during the same time interval.

1. A sled is being pulled to the left by 5 dogs, each dog pulling with 6 Newtons of force. Find the net force (ignore friction).
2. If a person pulls on a cart to the right with a force of 10N and a second person pulls to the left with a force of 3N, what is the net force on the cart ignoring all other forces?
3. A 2N and 6N force pulls on an object to the right and a 4N force pulls to the left a 0.5kg object. What is the net force on the object if you ignore all other forces?
4. A 20kg bike accelerates at 10m/s^2. With what force was the person pedaling if friction exerted a force of 100N
5. If a person is pushing a cart with a force of +40N, friction is -10N and the cart accelerates at 0.5m/s^2, what is the mass of the cart?

It’s cold outside and you decide to cook some pasta. As you boil the noodles, the kitchen window begins to fog up. Which processes are at work here?
evaporation and thawing
condensation and evaporation
vaporization and condensation
boiling and freezing
Answer:
Condensation and evaporation.
Explanation:
Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets.

Why do we give shots in the neck and not anywhere else in pigs ?
Answer:The normal favored site in weaners, producers, finishers, and grown-ups is up to 70mm behind the base of the ear. Little piglets are regularly infused into the ham of the rear leg in light of the fact that there isn't a lot of muscle on the neck. This isn't suggested in producers/finishers in view of the chance of abscesses.

A girl rides her scooter to school, a total distance of 4.5km. She has to slow down twice to cross busy streets, but overall the journey takes her 0.65h. What is her average speed during the trip?
Answer:
6.93 km/h
Explanation:
To calculate her average speed, we need the "speed" formula, which is:
average speed = distance / time
You plug in your numbers and it will give you the answer.
Speed = 4.5km/0.65hr
= 6.923 km/h
Using simple language, explain how your demonstration shows the effect of distance on electric forces. Use the terms electric charge, electric field, and electric force.
Explanation:
For a charge concentrated nearly at a point, the electric field is directly proportional to the amount of charge; it is inversely proportional to the square of the distance radially away from the centre of the source charge and depends also upon the nature of the medium.
The electrical forces that exist between two charged objects will be inversely related to the distance of separation that's between the objects.
Coulomb's law describes the electric force between charged objects. It should be noted that gravitational force and electric forces reduce with the square of the distance between the objects.
Every constituent of matter possesses an electric charge that can either be positive, negative or zero. In electrostatics, the electrical forces that exist between two charged objects will be inversely related to the distance of separation that's between the objects.
When the separation distance is increased, it'll lead to a reduction in the force of attraction between the objects.
