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

Describe how an earth wire and a fuse can protect an iPad with a metal casing
- 5 clear simple points
Answer: Find the answer in the explanation
Explanation:
The earth wire act as a protective conductor in which current flows to the earth. Whenever there is a faulty flow of current, the earth wire will protect an iPad with a metal casing from letting you get shocked by allowing the faulty current to flow directly to the earth.
With the use of fuse, the wire break when it detects a faulty flow of current and the device will automatically switch off because of break in circuit.
These are to protect you from electric shock from the iPad metal casing.
how does the weight of a paper airplane affect the distance it will travel
The larger the paper airplane the more it will weigh, the more it weighs the more lift will be needed to keep it flying. Eventually weight will become greater than lift and the paper airplane will decend to the ground. In adition the larger the paper airplane the larger its wings can be.

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.

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
1) Johnny completing the spring lab, and makes 12 waves in 10 seconds. What is the
frequency of the waves Johnny makes?
Answer:
1.2 Hz
Explanation:
Frequency: This can be defined as the number of cycles completed in one seconds. The unit of frequency is Hertz (Hz)
From the question above,
f = N/t.................... Equation 1
Where f = frequency, N = number of wave or cycle completed by Johnny, t = time take to complete the waves.
Given: N = 12 waves, t = 10 s
Substitute into equation 1
f = 12/10
f = 1.2 Hz
True or false:Coordination is the ability to use the senses together with body parts during movement?
Answer:
Coordination is the ability to use the senses together with body parts during movement.
This statement is true.
For example, dribbling/juggling a soccer ball. Using feet and eyes together is called feet-eye coordination.

A guitar string is 0.620m long, and oscillates at 234Hz. What is the velocity of the waves in the string? m/s
Answer:
v = 72.54 m/s
Explanation:
We have,
Length of a guitar string is 0.62 m
Frequency of a guitar string is 234 Hz
For guitar string,
[tex]L=2\lambda\\\\\lambda=\dfrac{L}{2}\\\\\lambda=\dfrac{0.62}{2}\\\\\lambda=0.31\ m[/tex]
The velocity of the wave in the string is given by :
[tex]v=f\lambda\\\\v=234\times 0.31\\\\v=72.54\ m/s[/tex]
So, the velocity of the waves in the string is 72.54 m/s.

A sound wave traveling at STP has a period of .0023 seconds. The wavelength of this sound is closest to
1)1.4E5
2)6.9E-6
3)0.76m
4)76m
Answer: 3
Wavelength = 0.76m
Explanation:
When sound wave is travelling at standard temperature and pressure ( STP), its speed will be equal to normal speed of sound which is equal to 331 m/s
Given that the period of the wave is 0.0023 seconds.
Wave speed = wavelength/period
Substitute the wave speed and the period to obtain wavelength
331 = wavelength/0.0023
Cross multiply
Wavelength = 331 × 0.0023
Wavelength = 0.7613 metre
The wavelength of this sound is closest to 0.76 m
How are
global warming and the
carbon cycle related?
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.

Based on the field lines, what are the poles of the
magnets?
O X: north
Y south
X: south
Y north
X north
Y north
Х

X south
Y south
Answer:
The answer is C. X:north Y: north
Explanation:
Just took the test
Based on the field lines poles of the magnets X=North and Y=south
What are the poles of X and Y?Every magnet has the two poles that is north and the south. similarly earth also have two poles north and south and acts as a magnet.
just from that concepts the filed lines near the poles X and Y of the two magnets have north poles.
Hence based on the field lines poles of the magnets X=North and Y=south

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.

What is the mass number of the missing daughter nuclei?
Answer:
90
Explanation:
The mass number of the missing daughter nuclei can be obtained as shown in the attached photo.
Answer: 90
Explanation:
To calculate the mass number of the missing daughter nuclei, the equation must be balanced.
The sum of the mass number in the left hand side = 1 + 235 = 236
The sum of mass number in the right hand side must be equal to 236.
Then, 236 - (143 + 3×1)
236 - ( 143 + 3)
236 - 146 = 90

A positively charged spherical object is placed equidistant between two other identical uncharged spherical objects. How would the charges in the middle sphere be distributed?
Answer: The charge in the middle sphere will be distributed by induction.
Explanation: The charge in the middle sphere will be distributed through induction. The ends of the two uncharged bodies develop same charges and mutual attraction occurs. The positive charged body pushes the positive charged of the two uncharged bodies farther away and attracts the negative electrons in them.
