Kepler-186f is an exoplanet that orbits a star other than the Sun. Its star is the red dwarf Kepler-186. It is the first planet to be discovered that orbits its star at a distance like Earth’s distance from the Sun. If Kepler-186f is approximately 5.4 x 1010 meters from Kepler-186, how long does it take for light from the star to reach the exoplanet? The speed of light is 3.0 x 108 m/s. It takes 3 minutes
Answer:
t = 180 s = 3 minutes
Explanation:
The formula for the uniform speed of any object or element is given as:
V = S/t
t = S/V
where,
S = Distance between star and exoplanet = 5.4 x 10¹⁰ m
V = Speed of the light = 3 x 10⁸ m/s
Therefore, using these values in the equation, we get:
t = (5.4 x 10¹⁰ m)/(3 x 10⁸ m/s)
t = 180 s = 3 minutes
Hence, the light must reach the exoplanet in 3 minutes.

if an earthquake has a velocity of 41 m/s and a wavelength of 225 meters.
what is the earthquakes frequency?
Answer:
Frequency = 5.49Hz
Explanation:
Given the following data
Velocity = 41m/s
Wavelength = 225m
[tex] Velocity = wavelength * frequency [/tex]
Making frequency the subject of formula, we have;
[tex] Frequency = \frac {wavelength}{velocity} [/tex]
Substituting into the equation, we have;
[tex] Frequency = \frac {225}{41} [/tex]
Frequency = 5.49Hz
Therefore, the frequency of the earthquake is 5.49 Hertz.

A farmer is walking through a field at a
velocity of +0.5 meters per second (m/s)
relative to the ground. At the same time, he
is throwing seeds in front of him at a
velocity of +2.1 m/s relative to himself.
What is the velocity of the seeds relative to
the ground as they travel through the air?
Answer:
The velocity of the seeds relative to the ground as they travel through the air is V = +2.6 m/s
Explanation:
Let V be the velocity of the seeds relative to the ground, v be the velocity of the seeds relative to the farmer and v' be the velocity of the farmer relative to the ground.
By vector addition, V = v + v'
Since v = the velocity of the seeds relative to the farmer = +2.1 m/s and
v' = the velocity of the farmer relative to the ground = +0.5 m/s
Then,
V = v + v'
V = +2.1 m/s + (+0.5 m/s)
V = +2.6 m/s
So, the velocity of the seeds relative to the ground as they travel through the air is V = +2.6 m/s

Earth is 1.5 ✕ 1011 m from the Sun. Neptune is 4.5 ✕ 1012 m from the Sun. How does the gravitational field of the Sun on Neptune (gSN) compare to the gravitational field of the Sun on Earth (gSE)?
Answer:
The gravitational field of the Sun on Earth is greater than the gravitational field of the Sun on Neptune.
Explanation:
From Newton's law of universal gravitation,
F = [tex]\frac{GMm}{R^{2} }[/tex] ............. 1
where F is the force, G is the gravitational constant, M is the mass of the bigger object, m is the mass of the smaller object and R is the distance between their centers.
Also, Newton's second law of motion state;
F = mg ................ 2
where F is the force, m is the mass and g is the gravitational force.
Equating 1 and 2,
mg = [tex]\frac{GMm}{R^{2} }[/tex]
⇒ g = [tex]\frac{GM}{R^{2} }[/tex]
Given that the distance between the Sun and Earth is 1.5 x [tex]10^{11}[/tex] m, then the gravitational field of the Sun on Earth,
gSE = [tex]\frac{GM}{(1.5*10^{11}) ^{2} }[/tex]
= [tex]\frac{GM}{2.25*10^{22} }[/tex] .................. 3
Given that the distance between the Sun and Neptune is 4.5 x [tex]10^{12}[/tex] m, then the gravitational field of the Sun on Neptune,
gSN = [tex]\frac{GM}{(4.5*10^{12}) ^{2} }[/tex]
= [tex]\frac{GM}{2.025*10^{25} }[/tex] ............. 4
Comparing equations 3 and 4, it can be observed that gSE > gSN.
The gravitational field of the Sun on Earth is greater than the gravitational field of the Sun on Neptune.

Answer:
Potential
Explanation:
The water in the bathtub has more potential energy than that in the tea cup because it has a greater number of water molecules.
Mass is a parameter that is very instrumental in determining potential energy.
The potential energy of a body is the energy due to the position of that body.
Potential energy = mass x acceleration due gravity x height
Mass is the amount of matter in a substance. Water in the tub will have more mass and contain a greater number of water molecules there in.
Since potential energy is directly proportional to mass, then, it will have a greater amount of potential energy.

Jupiter is made of gas(like Saturn, Uranus and Neptune). What would happen to the strength of gravity if you
a) moved away from Jupiter
b)Fell in to Jupiter
PLS HELP ME OMG ITS DUE TOMOROW AND I HAVE NO CLUE WHAT TO DO BEST EXPLANATION GETS BRAINLIEST
Answer:
a) The strength of gravity decreases if one moved away from Jupiter
b) The strength of gravity increases if one fell into Jupiter
Explanation:
The gravitational attraction is given by Newton law of gravitation as follows;
[tex]Force \ (strength) \ of \ gravity = \dfrac{G \times M \times m}{R^2}[/tex]
Where;
G = The universal gravitational constant = 6.67408 × 10⁻¹¹ m³/(kg·s²)
M = The mass of Jupiter
m = The mass of the nearby body
R = The distance between the centers of Jupiter and the body
From the equation, we have that the gravitational strength varies inversely with the square of the separation distance between two bodies
Therefore, as one moves away, R increases, and the strength of gravity reduces
Similarly as the body falls into Jupiter, R, reduces the gravitational strength increases.

Which one has greater potential energy? An 8 kg rock sitting on a 2.2 m cliff or a 6 kg rock sitting on a 3.2 m cliff.
Answer: The 6 kg rock sitting on a 3.2 m cliff.
Explanation:
The potential energy of an object of mass M that is at a height H above the ground us:
U = M*H*g
where g is the gravitational acceleration:
g = 9.8m/s^2
Then:
"An 8 kg rock sitting on a 2.2 m cliff"
M = 8kg
H = 2.2m
U = 8kg*2.2m*9.8 m/s^2 = 172.48 J
"a 6 kg rock sitting on a 3.2 m cliff"
M = 6kg
H = 3.2m
U = 6kg*3.2m*9.8m/s^2 = 188.16 J
You can see that the 6kg rock on a 3.2m cliff has a larger potential energy.
