How much would you have to eat for your appendix to explode ? I ate so much on thanksgiving and i need to know i’m very scared
Answer:
I don't think your appendix can explode because you ate too much honestly. It's not even possible to eat so much that your appendix explodes, and if you're feeling any pain it definitely isn't because your appendix is about to explode, believe me. Also you could just type it into the internet, that'd be a much faster solution.
What’s the answer to this question
Answer:
space = 66.24 [m]
Explanation:
To solve this problem we must remember that the average speed is defined as the relationship between a space traveled over a certain time.
[tex]Av = \frac{space}{time}[/tex]
where:
space [m]
Av = average velocity = 3.6 [m/s]
time = 18.4 [s]
[tex]space = 3.6*18.4\\space = 66.24 [m][/tex]

Categorize each quantity as being either a vector or a scalar. Explain your reasoning. a. 20 degrees Celsius b. 256 bytes c. 4000 Calories
Answer:
a. Scalar quantity
b. Scalar quantity
c. Scalar quantity
Explanation:
Generally, all physical quantities can be categorized into vector or scalar. Vector quantities can be described by both magnitude and direction, while scalar quantities can be described only by magnitude.
a. 20 degrees Celsius is a measure of a definite value of temperature, thus it is a scalar quantity. As temperature has no direction.
b. 256 byte is the storage capacity of an electronic device. It is a scalar quantity since it is described only by magnitude and no direction.
c. 4000 Calories is an amount of energy in a given substance. Thus, it is a scalar quantity.
true or false gravitational pull decreases with an increase of distance between two objects
Answer:
true! : )
(i underlined the place where the answer is the other information is just as important but if you do not want to read it you do not have to)
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. the greater the mass, the greater the gravitational pull. gravitational pull decreases with an increase in the distance between two objects. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

A book rest on a table. The book pushes downward on the table with a force of 8 N According to Newton's 3rd law of motion, what prevents the book from accelerating downward?
Answer:
In the case of the table and the book, the gravitational attraction is absolutely negligible, since they are both so tiny. The force that the table experiences because of the book is what is being called normal force. The table then exerts an equal and opposite force.
Explanation:
Explanation:
The law of motion states that for every action there is an equal yet opposite reaction. so that mean that the book is being acted on by another force which would be the table. It does not move because the table is acting on it with 8n of upward force creating an equilibrium keeping the book at rest.

Which of the following best describes the motion of the object in this p-t graph? please answer quickly i'm giving 40 points.
The object is accelerating.
The object is decelerating.
The object has positive velocity.
The object is moving to the left.
Explanation:
A position time graph gives the velocity of an object. Its slope gives the velocity of an object.
In the given figure, the distance covered by an object decreases with respect to time. It means the speed decreases uniformly. So, the object is decelerating. Hence, the correct option is (b).
Answer:
The object has positive velocity
Explanation:
The steeper the slope, the greater the velocity. For example, an object moving 50 m/s, east, will have a steeper slope than an object moving 25 m/s, east. The shape of the line also describes the object's motion. A straight line indicates an object with no acceleration. The object is moving at a constant velocity. A curved line indicates an object with a changing velocity. In other words, a curved line indicates acceleration. A completely horizontal line represents an object with zero velocity. The object is not moving.

When a ray of light passes through a boundary between two transparent media, it changes direction. What is this phenomenon known as?a. reflection.
b. refraction.
c. interference.
d. diffraction.
e. dispersion.
Answer:
The phenomenon is known as refraction. The correct option is B
Explanation:
Refraction is defined as the property of a change in the direction of light, when it passed from one medium to another. In the process of refraction, the direction to which the rsy of light follows changes as well as the velocity, but the frequency remains the same along the line of propagation.
The extent of propagation is determined by the nature of the medium allowing the propagation.If a ray of light hits the surface of a sheet of glass, some light will be reflected by the surface of the glass. However, much of the light will pass through the glass, because glass is transparent. This effect also o view with mediums such as water.
The reason why the light rays bends away from its normal direction is that light slows down when it passes from the less dense air into the denser glass or water.
Other properties of light includes:
--> light travels in a straight line
--> light can be reflected
--> light can be diffracted
--> light can be polarized

People who do very detailed work close up, such as jewellers, often can see objects clearly at much closer distance than the normal 25.0 cm. What is the power of the eyes of a woman who can see an object clearly at a distance of only 9.75 cm? Assume a distance from the eye lens to the retina of 2.00 cm. Number ________ diopters What is the size of the image of a 2.00 mm object, such as lettering inside a ring, held at this distance? Enter your answer as a positive number if the image is upright, and negative if it is inverted. Number ________mmWhat would the size of the image be if the object were held at the normal 25.0 cm? Number ________mm
Answer:
a) P = 60.26 diopter , b) h´ = -0.4 mm , c) h´ = -0.16 mm
Explanation:
a) For this exercise we use the equation for thin lenses
1 / f = 1 / p + 1 / q
where f is the focal length, p the distance to the object and q the distance to the image
in this case q is the distance from the lens to the retina q = 2.00 cm
the distance p is the distance from the object to the lens p = 9.75 cm
1 / f = 1 / 9.75 + 1/2
1 / f = 0.6026 cm⁻¹
power is the inverse of the focal length in meters
P = 1 / f [m]
P = 0.6026 102
P = 60.26 diopter
b) the size of the image
m = - p / q
m = - 2 / 9.75
m = -0.2 X
if we assume that the object is right
m = h´ / h
h´ = m h
h´ = -0.2 2
h´ = -0.4 mm
if the height of the object h is straight the image and inverted
c) if the object were at p = 25.0 cm
m = - 2/25
m = -0.08
h´ = -0.08 2
h´ = -0.16 mm
the image would be much smaller
A screen is placed 50.0 cm from a single slit, which is illuminated with light of wavelength 690 nm. If the distance between the first and third minima in the diffraction pattern is 3.00 mm, what is the width of the slit?
Answer:
d = 2.3 x 10⁻⁴ m = 0.23 mm
Explanation:
In a Young's Double Slit experiment the distance between two consecutive minima is given as:
Δx = λL/d
for, the distance between the 1st and 3rd minima it will become:
2Δx = 2λL/d
where,
2Δx = distance between 1dt and 4rd minima = 3 mm = 0.003 m
λ = wavelength = 690 nm = 6.9 x 10⁻⁷ m
L = Distance of Screen = 50 cm = 0.5 m
d = width of slit = ?
Therefore,
0.003 m = 2(6.9 x 10⁻⁷ m)(0.5 m)/d
d = 6.9 x 10⁻⁷ m/0.003 m
d = 2.3 x 10⁻⁴ m = 0.23 mm
