Which diagram above shows a box in equilibrium
Explanation:
box no. 4 I think
plzzzz mark me brainliest if it helps you then
If two same forces acting on a body in opposite direction, they will cancel each other. In box 2, 2 N is acting from both top and bottom and it will cancel. Similarly, 5 N is acting from both left and right and result in cancellation in magnitude. Therefore, box 2 cannot be displaced and it is equilibrium.
What is force?Force is an external agent acting on a body to change it from the state of motion or rest. Force is dependent on the mass of the body. Force is a vector quantity and thus, having a magnitude and direction.
If two same forces acting on a body from same directions, then the resultant force will be the sum of the two forces. If these forces are acting in opposite directions, then they will cancel each other in magnitude.
Here, in box 2 equal forces are acting from opposite directions. 2 N from top and bottom will cancel each other and similar for 5 N from left and right. Hence, the net force acting upon the box-2 is zero. Thus, box 2 is said to be in equilibrium.

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 football player kicks a ball with a mass of .55 kg. The average acceleration of the
football was 14.9 m/s2. How much force did the kicker supply to the football?
8.2 N
O 8.2 m/s²
35.24 N
35.24 m/s2
Answer:
8.2N
Explanation:
The answer is in Newtons (N) so this means answer 2 and 4 do not work.
8.2N is the answer because 0.55x14.9=8.195N
The answer does not exactly 8.2 but when you round it equals 8.2.
Answer:
8.2 N

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.

Identify at least one example each of absorption, transmission, reflection, and refraction of waves in this photograph.
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.
Explanation:
A box moves 10 m horizontally when force F = 20 N is applied at an angle θ=30° degrees. What is the work done on the box by force F during the displacement?
Given that,
Distance moved by the box, d = 10 m
Force applies, F = 20 N
It is applied at an angle of 30 degrees.
To find,
The work done on the box by the force F during the displacement.
Solution,
The work done by an object is given by the formula as follows :
[tex]W=Fd\cos\theta\\\\W=20\times 10\cos(30)\\\\W=173.20\ J[/tex]
So, the required work done on the box by the force is 173.20 J.
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.

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.

Answer:
i think its the 2nd law
Explanation:
based on Newton's first law of motion describe what happens if you try and push a student. What happens if the student pushes back?
Answer:
If you push someone, then you are exerting force which will push them into motion. Same goes for when they push you.
When the mass of a body is constant, then its acceleration is directly proportional to the force acting on it. When the force acting on a body is constant, then its acceleration is inversely proportional to the mass of the body .

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.
