Answer:
La distancia por carretera de Chitré a Parita es de 12 km o 39370.08 pies.
Explanation:
La regla de tres es una forma de resolver problemas de proporcionalidad entre tres valores conocidos y un valor desconocido, estableciendo una relación de proporcionalidad entre todos ellos.
Si la relación entre las magnitudes es directa, es decir, cuando una magnitud aumenta, también lo hace la otra (o cuando una magnitud disminuye, también lo hace la otra), se debe aplicar la regla directa de tres. Para resolver una regla directa de tres, se debe seguir la siguiente fórmula, siendo a, b y c los valores conocidos y x el valor a determinar:
a ⇒ b
c ⇒ x
Entonces [tex]x=\frac{c*b}{a}[/tex]
La regla directa de tres es la regla que se aplica en este caso donde hay un cambio de unidades. Para realizar esta conversión de unidades, primero debes saber que 1 km = 3280,84 pies. Entonces, si 1 km son 3280,84 pies, ¿cuántos pies son 12 km?
1 km ⇒ 3280.84 pies
12 km ⇒ x
[tex]x=\frac{12 km*3280.84 pies}{1 km}[/tex]
x= 39370.08 pies
La distancia por carretera de Chitré a Parita es de 12 km o 39370.08 pies.
How do we weigh planets? Explain your thinking
Planets in the solar system revolve around the Sun in an orbital path and can vary from rocky and terrestrial objects to gaseous and liquid object. Which set of characteristics is unique to the outer planets
Answer:
Gaseous; liquid.
Explanation:
A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.
Some examples of the planet are Mars, Venus, Earth, Mercury, Neptune, Jupiter, Saturn, Uranus, Pluto, etc.
Basically, the planets are divided into two (2) main categories and these includes;
I. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.
II. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.
These outer planets are made mostly of gases (hydrogen and helium) causing them to be less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.
In conclusion, Planets in the solar system can vary from rocky and terrestrial objects to gaseous and liquid object.
However, the set of characteristics which is unique to the outer planets are gaseous and liquid.

Answer:
271 K
Explanation:
Answer:
The temperature of Nitrogen is 270.85 K.
Explanation:
What is perfect gas ?A gas that follows Boyle's law , Charle's law and law of pressure , is called perfect gas.
Given data;
[tex]P =101.3 KPa , V = 0.08 m^{3} , \\ n = 3.6 mol , R = 8.31\\T = ?[/tex]
By the formula,
P.V = n .R.T

Beryllium-11 has a half-life of 13.81 s. What percent of the initial sample will remain aft er 30.0 s?
Answer:
Let N0 be the initial atoms of Be11
N0 / 2^1 = N0 / 2 Number of Be11 after 1 half-life
N0 / 2^2 = N0/ 4 Number of Be11 after 2 half-lives
30/13.81 = 2.17 half lives
N0 / 2^2.17 = N0 / 4.51 = .222 N0 or 22.2 % of atoms remain
The percentage of the initial sample that will remain after 30.0 s is 22.2 % of atoms remain.
What is half-life?A half of existence is the duration required for something to reduce in size by half. The phrase is most frequently used in reference to radioactive decay, which takes place as unstable atomic particles weaken. There are 29 known factors that can operate in this way.
Every chemical has a unique half-life. Since carbon-10, for instance, has a half-life of only 19 seconds, it is impossible for this isotope to be found in nature.
Let No of the initial atoms of Beryllium-11
No / 2¹ = N0 / 2 Number of Be11 after 1 half-life
No / 2² = N0/ 4 Number of Be11 after 2 half-lives
30 / 13.81 = 2.17 half lives
No / 2²·¹⁷ = N0 / 4.51 = .222 N0 or 22.2 % of atoms remain
Therefore, the percentage of the initial sample will remain after 30.0 s is 22.2 %.

Why do fruits fall down when the branch is shaken?
Answer:
Explanation:
Fruits fall down when the branch is shaken because when force is applied to shake the branch,the branch comes in motion but the fruits tend to be at rest
due to inertia of rest which results the falling of fruits.
11. (a)What downward force is acting on you when you go down a waterslide? (b)What type of friction is
present? (c)If the waterslide were dry explain what type of friction in would be and (d)how that
changes your speed? (4 points)
Answer:
a) "gravitation" is the force causing you to go down a waterslide
b) It is "fluid friction" as a solid object (our body) moves over a fluid (the water)
c) It would become "sliding friction" since two solid surfaces slide over each other
d) fluid friction being the weakest friction, switching to sliding friction means a higher decrease in speed and therefore removing the water from a slide will decrease our speed
How far will a brick starting from rest fall freely in 3 seconds
Answer:
When object falls freely we can say
its initial speed will be ZERO
and its acceleration due to gravity must be
a = g = 9.8 m/s^2a=g=9.8m/s2
Now we need to find the distance of free fall in 3 s of time
So here we will use kinematics
y = v* t + \frac{1}{2} at^2y=v∗t+21at2
now we will plug in all values in it
y = 0 + \frac{1}{2}* 9.8 * 3^2y=0+21∗9.8∗32
y = 44.1 my=44.1m
So it will fall by total distance of 44.1 m

The current across a certain resistor can be found using Ohm's Law, as before:
Vi = RiIi
where:
Vi is the voltage drop across the resistor
Ri is the resistance of the resistor
Ii is the current through the resistor
In this problem:
R2 = 8Ω is the resistor we are considering
V₂ = 110V is the voltage drop across that resistor (in a parallel circuit, the voltage drop is the same across each resistor)
Solving for I, we find the current through it:
I₂ = V₂/R₂ = 110/8 = 13.7A (see that "V₂/R₂" and "110/8" part as fraction)

Answer:
y = 33.93 10⁵ m
Explanation:
This is an interference exercise, for the contributory interference is described by the expression
d sin θ = m λ
let's use trigonometry for the angle
tan θ = y / L
how the angles are small
tan θ = sin θ / cos tea = sin θ
we substitute
sin θ = y / L
d y / L = m λ
y = m λ L / d
the light fulfills the relation of the waves
c = λ f
λ = c / f
λ = 3 10⁸ /375
λ = 8 10⁵ m
first order m = 1
let's calculate
y = 1 8 10⁵ 4030 10-9 / 950 10-9
y = 33.93 10⁵ m

Motion is
displacement
a change of position in relation to another object
an object you look at to determine if something is moving
speed
Explanation:
When something is moving, we call it is in motion. It can be also defined as a change of position in relation to another object.
When an object is not moving at all, we call that it was at rest.
To be in motion, there must be a change in position.
Hence, the correct options are "a change of position in relation to another object" and "something is moving".
A beam of light shines on a plane mirror with an angle of incidence of 40°. The reflected light then hits another parallel plane mirror. What is the angle of reflection from the second mirror? A. 40° B. 50° C. 80° D. 90° E. 140°
Answer:
40degrees
Explanation:
Since the mirrors are parallel, the angle of incidence on the first mirror will be the same as the angle of incidence on the second mirror.
Angle of incidence on the second mirror = 40degrees
According to the second law of reflection, the angle of incidence is equal to the angle of reflection. Hence;
angle of incidence = angle of reflection = 40degrees
This shows that the angle of reflection from the second mirror is 40degrees

Monochromatic light falling on two very narrow slits 0.048mm apart. Successive fringes on a screen 5.00m away are 6.5cm apart near the center of the pattern.What is the wavelength and frequency of the light?
Answer:
λ = 5.85 x 10⁻⁷ m = 585 nm
f = 5.13 x 10¹⁴ Hz
Explanation:
We will use Young's Double Slit Experiment's Formula here:
[tex]Y = \frac{\lambda L}{d}\\\\\lambda = \frac{Yd}{L}[/tex]
where,
λ = wavelength = ?
Y = Fringe Spacing = 6.5 cm = 0.065 m
d = slit separation = 0.048 mm = 4.8 x 10⁻⁵ m
L = screen distance = 5 m
Therefore,
[tex]\lambda = \frac{(0.065\ m)(4.8\ x\ 10^{-5}\ m)}{5\ m}[/tex]
λ = 5.85 x 10⁻⁷ m = 585 nm
Now, the frequency can be given as:
[tex]f = \frac{c}{\lambda}[/tex]
where,
f = frequency = ?
c = speed of light = 3 x 10⁸ m/s
Therefore,
[tex]f = \frac{3\ x\ 10^8\ m/s}{5.85\ x\ 10^{-7}\ m}\\\\[/tex]
f = 5.13 x 10¹⁴ Hz
If a sled has a mass of 4kg what is the force of gravity on the sled?
Answer:
Explanation:
Gravity pulls everything down at the same rate of 9.8 m/s/s. If you're looking for the normal force, which is the same as the weight of the object, we'll find that, just in case.
w = mg which says that the normal force/weight of an object is equal to its mass times the pull of gravity:
w = 4.0(9.8) so
w = 39N

A student applies a 10 N force to a wood block with a mass of 5 kg. The block is pushed across four different surfaces. The accelerations of the block are recorded. Which surface showed the least friction?
The complete question is as follows: A student is subjected to a reaction force of 10 N northward from a 5 kg block while pushing the block over a smooth, level surface. Ignoring friction, what is the acceleration of the block?
Answer: The acceleration of the block is [tex]2 m/s^{2}[/tex].
Explanation:
Given: Force = 10 N
Mass = 5 kg
It is known that force applied on an object is the product of mass and acceleration.
Mathematically, [tex]F = m \times a[/tex]
where,
F = force
m = mass
a = acceleration
Substitute the values into above formula as follows.
[tex]F = m \times a\\10 N = 5 kg \times a\\a = \frac{10}{5}\\= 2 m/s^{2}[/tex]
Thus, we can conclude that the acceleration of block is [tex]2 m/s^{2}[/tex].
