Answer:
Fever or elevated body temperature might be caused by:
A virus.
A bacterial infection.
Heat exhaustion.
Certain inflammatory conditions such as rheumatoid arthritis — inflammation of the lining of your joints (synovium)
A malignant tumor.
Many illness-causing microbes do best at the body's normal temperature. A fever raises the temperature beyond which certain microbes need to reproduce. A fever also kicks your child's immune system into high gear, spurring the rapid production of bug-clobbering white blood cells.

a 1 kg box is being push across the floor. When pushed, the box accelerates at a rate of 1m/s 2. with what force is someone pushing on the box?
Answer:
Force, F = 1 N
Explanation:
We have
Mass of a box is 1 kg
Acceleration with which it is pushed is 1 m/s²
It is required to find the force acting on the box.
Force, F = ma
[tex]F=1\ kg\times 1\ m/s^2\\\\F=1\ N[/tex]
So, the force of 1 N is acting on the box.
For example, imagine that your little sister wants to move her bed from one corner of the room to the other. She gives the bed a light push, but the bed does not move. She gives it a stronger push, but it still does not move. She gives it her strongest push, and still nothing happens. She calls you for help. Only when both of you push together as hard as you can does the bed finally start to move. Why? Why did the bed not move when your sister pushed it by herself? What kept it from moving?
Answer:
When the sister pushed the bed by herself, she could not move it at all because of gravity and the weight of the bed. Due to the beds mass it prevented the sister from pushing the bed, but since she received help from her brother, their strengths combined to be able to push the bed
Why is air considered a fluid
Answer:
A fluids is any substance that flows. Air is made of stuff, air particles, that are loosely held together in a gas form. Although liquids are the most commonly recognized fluids, gasses are also fluids. Since air is a gas, it flows and takes the form of its container.
Explanation:
Because it possesses the essential characteristics of fluids, air is regarded as a fluid.
A substance that may flow and take on the shape of its container is called a fluid. Here are several explanations for why air is seen as a liquid:
Air has the ability to flow and move freely. It can easily alter its location or direction of movement because it is neither hard nor fixed in shape.Air is fluid, allowing air molecules to readily flow past one another.Compressibility: Pressure-induced compression or expansion of air is possible. Air, like other fluids, has a property known as buoyancy that allows it to pull upward.Thus given these qualities, air satisfies the requirements for fluidity and is frequently categorised as such in the study of fluid mechanics.

What is the frequency of UV light that has an energy of 2.39 × 10 -18 J?
Answer:
3.60 × [tex]10^{15}[/tex] Hz
Explanation:
[tex]\frac{2.39 * 10^{-18} J}{6.63 * 10^{-34} J.s}[/tex]
The frequency of UV light that has an energy of 2.39 × 10 -18 J is 3.60 × Hz.
What do you mean by frequency?The term frequency refers to the number of waves that pass a fixed point in unit time. It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Moreover, frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency for clarity, and is distinct from angular frequency. Frequency is measured in hertz which is equal to one event per second.
Therefore, the number of vibrations that a sound wave is making is called its frequency ( f ). Frequency can also be defined as the number of waves passing a given point in one second. Frequency is measured in hertz (Hz).

Why is tornadoes hitting the east coast of the USA?
Answer:
The outbreak of tornadoes that tore across the Gulf and the East Coast Tuesday and Wednesday was unusual for two reasons. For one thing, the severe weather encompassed a significant swath of the country. For another, winter is the least likely time for tornadic thunderstorms.
Explanation:
The outbreak of tornadoes that tore across the Gulf and the East Coast Tuesday and Wednesday was unusual for two reasons. For one thing, the severe weather encompassed a significant swath of the country. For another, winter is the least likely time for tornadic thunderstorms.
And yet tornadoes are an expected part of life in the United States—especially in the multi-state area known as Tornado Alley. (Florida, too, sees a disproportionately high number of tornadoes, because of its frequent thunderstorms.) The United States gets more tornadoes, by far, than any other place on the planet. It averages about 1,250 twisters a year. Canada, which sees about 100 tornadoes per year, is a “distant second,” according to the National Centers for Environmental Information.

You are kicking your soccer ball back and forth on a soccer field. You kick the ball forward for 10 m. You turn completely around and kick the ball back for 20 m. Your turn again and kick the ball forward for 40 m. What is your distance and what is your displacedment?
Answer:
1.) Total distance = 70 m
2.) Total displacement = +30m
Explanation:
Distance is a scaler quantity. That is, we will be concerned about its magnitude only and not direction.
Total distance = 10 + 20 + 40 = 70 m
While displacement is a vector quantity. We will consider both the magnitude and its direction.
Forward direction will be positive while backward direction will be negative
Total displacement = +10 - 20 + 40
Total displacement = +30 m
A tuba creates a 4th Harmonic of frequency 116.5 Hz. When the first valve is pushed, it opens an extra bit of tubing 0.721m long. What is the new frequency of the 4th Harmonic? Hz
Answer: New frequency = 103.3Hz
Explanation:
Given that the
Frequency F = 116.5 Hz
The tube is an opened tube.
The relationship between wavelength and the length of the tube is
λ = 2L/n
Where
λ = wavelength
L = length of the tube
n = number of harmonic
For 4th harmonic,
λ = 2L/4 = L/2
But wave speed V = F(λ)
Substitutes (λ) into the wave speed formula
V = FL/2
Let's assume that the V is the speed of sound = 330m/s
Substitutes the V and F into the formula above.
330 = 116.5L/2
Cross multiply
660 = 116.5L
L = 660/116.5
L = 5.67 m
Given that the first valve is pushed, it opens an extra bit of tubing 0.721m long.
New length = 5.67 + 0.721 = 6.39 m
New frequency will be
330 = 6.39F/2
Cross multiply
660 = 6.39F
F = 660/6.39
F = 103.3 Hz

A 41kg girl sits on the edge of a merry-go-round. If she travels
at 0.02ms and the radius of her motion is 2.1m, what is the centripetal force acting upon her?
Answer:
Centripetal force F = 0.0078 N
Explanation: Given that the
Mass M = 41 kg
Velocity V = 0.02 m/s
Radius r = 2.1 m
Centripetal force F = MV^2/r
Substitutes all the parameters into the formula
F = (41 × 0.02^2)/2.1
F = ( 41 × 0.0004 )/2.1
F = 0.0164/2.1
F = 0.0078 N
The centripetal force acting upon her is 0.0078 Newton

HURRY ITS DUE IN A COUPLE MINUTES!!
Answer:
The carbon cycle plays a key role in regulating Earth's global temperature and climate by controlling the amount of carbon dioxide in the atmosphere. The greenhouse effect itself is a naturally occurring phenomenon that makes Earth warm enough for life to exist.
As the burning of fossil fuels and landscape alterations, such as deforestation and industrial agriculture, mobilize fossil carbon into the atmosphere, the earth's carbon cycle is pushed out of balance and climate changes. Human generated climate change is an enormous perturbation in the global carbon cycle.

A stone is dropped from a 75-m- high building . When this stone has dropped 15 m, a second stone is thrown downward with an initial velocity such that the two stones hit the ground at the same time. What was the initial velocity of the second stone?
Answer:
The initial velocity of the second stone is 34.3 m/s
Explanation:
The distance height covered by the second stone will be
75m - 15m = 60 m
Since the two stones hit the ground at the same time.
Using third equation of motion, which state that;
V^2 = U^2 - 2gH
Where
U = Initial velocity
V = final velocity
H = 60 m
g = 9.81 m/s^2
As the stone reaching the ground, that is, coming to rest, V = 0. Therefore,
Substitute all the parameters into the equation
0 = U^2 - 2 × 9.81 × 60
U^2 = 1177.2
U = 34.3 m/s
The initial velocity of the second stone is 34.3 m/s

Which two adjacent planets have the largest distance between them?
Which two adjacent planets have the smallest distance between them?
What is the general pattern of the planetary distances from the sun?
Which planet has the longest day?
Which planet has the longest year?
Explain why the outer planets have a lower density than the inner planets.
Answer:
The two neighboring planets with the greatest distance between them is Neptune and Uranus. This happens when they are at the opposite sides of the Sun at approximately. They are 4500 million miles away from each other.
If by adjacent you mean next to each other, in terms of the order of planets in our Solar System, then the closest would be Earth and Venus; which are separated by about 38,000,000 kilometres when in opposition.
I am not sure about the general patterns..
Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days.
A year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days). It is obvious because it is also the farthest with the longest orbit.
Outer planets are less dense than the inner planets because they posses a big volume but contains not much mass. Try to imagine 2 rocks, one is big, but is hollow or have a lot of holes; and the other is small, but solid with no holes.
