Answer:
The earth has more gravity so that means if you jump out of a plane without a parachute u will die. But the moon has less gravity so u will not die when hit ground. But someone can probally explain it better than me.
More gravity equals more speed in some cases like falling

A beam of light from a laser pen passed through the air and then through a glass plate. Which diagram accurately models this phenomenon? Use evidence and scientific reasoning to defend your claim.
Explanation:
the second diagram depicts the phenomenon which is refraction and this stems from light moving from a medium to another......and in this case light moves from a less dense medium to a denser medium hence is refracted away from the normal(the straight line between the medium of air and glass)
PLS GIVE BRAINLY
Diagram B shows the refraction event and this is from light to medium, in this case, the light travels from a slightly narrower area to a compact area and is, therefore, further away from the normal (vertical line between the air and glass).
When a ray of light travels from a central location?When a ray of light travels from a dense area to a rare place, it bends away from normal.
How do you calculate the refractive index?Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.

If the gravitational force between a planet of mass M and a satellite of mass m at distance is 2.5 * 10 ^ 3 * N what is the force exerted on a larger satellite of mass 2m , at a distance 0.8r away from planet M ?
Answer:
F = 7.8 10³ N
Explanation:
For this exercise we will use the law of universal Gravitational
F = G M m / r²
for initial conditions
F₀ = G M m₀ / r₀²
They tell us that the mass changed at m = 2m distance at r = 0.8r₀
we substitute
F = G M 2m₀ / (0.8 r₀) ²
F = (GM m₀/ r₀²) [tex]\frac{2}{0.64}[/tex]
F = 3.125 F₀
let's calculate
F = 3.125 2.5 10³
F = 7.8125 10³ N
Calcula en watts y en caballos de fuerza la potencia mecánica de una grúa que efectúa un trabajo de 60000 joules en 3 segundos
Answer:
I. Potencia mecánica = 20000 Watts.
II. Potencia mecánica = 26 caballos de fuerza.
Explanation:
Dados los siguientes datos;
Trabajo realizado = 60000 julios
Tiempo = 3 segundos
Para encontrar el poder;
I. En vatios:
Potencia mecánica = trabajo realizado / tiempo
Potencia mecánica = 60000/3
Potencia mecánica = 20000 Watts
II. En caballos de fuerza;
1 vatio = 0.0013 caballos de fuerza
20000 Watts = 20000 * 0.0013 = 26 caballos de fuerza.
Potencia mecánica = 26 caballos de fuerza.

You are a drop of water going through the water cycle. Where doyou go?How do you get there? What processes do you go through?Include at least three phases of the water .
Answer:
If I were a drop of water and present in the ocean or any other aquatic system I should have moved in the water cycle as due to heats the water of the aquatic system such as the ocean becomes hot and evaporated turning into vapour, a gaseous phase of water.
Then vapour colloids with cooler air, and become cooler and convert into drops of water again which is called condensation. Drops of water again get back to the earth surface it can be in the form of rain, snow (ice form of water) termed as precipitation.
The three phases of the water cycle are
---> evaporation ---- > condensation -----> precipitation----
A tennis ball and a bowling ball are both rolled down a bowling lane. If the
balls are rolling in the same direction at the same speed, which of the
following is true?
A. The balls have the same momentum because they have equal
velocities.
B. The tennis ball has greater momentum because its mass is less
than the mass of the bowling ball.
C. The balls have no momentum because they have equal velocities,
D. The bowling ball has greater momentum because its mass is
greater than the mass of the tennis ball.
Answer:
D. The bowling ball has greater momentum because its mass is
greater than the mass of the tennis ball.
Explanation:
The momentum of a body is defined as the product of mass and velocity. That is;
p = mv
This implies that the momentum of a body depends both on its mass and velocity respectively.
The question clearly states that the tennis ball and the bowling ball have the same speed and are rolling in the same direction. However, the bowling ball has a larger mass compared to the tennis ball hence it possesses a greater momentum than the tennis ball.

An observer notices that 12 waves pass by in 4 seconds. What is the frequency of these waves? 0.33 Hz 16 Hz 48 Hz 3 Hz
Answer:
Frequency = 3 Hz
Explanation:
Frequency is a measure of Hertz. Recall that Hertz is the unit expressing cycles/second, where one second is the denominator of the fraction for simplicity. If there are 12 waves every four seconds, and one wave represents one cycle, dividing 12 waves by 4 seconds will give the answer of 3 waves (or cycles) per one second.
The frequency of these waves is 3 Hz. The correct option is D.
What is a frequency?Frequency is the number of cycles or oscillations of a wave that occur in one second, measured in Hertz (Hz). It is a fundamental property of waves and is directly related to the energy and wavelength of the wave. The higher the frequency of a wave, the more energy it carries and the shorter its wavelength.
The formula for frequency (f) is:
f = 1 / T
where f is the frequency in Hertz (Hz) and T is the period of the wave in seconds (s). The period is the time it takes for one complete cycle or oscillation of the wave to occur.
Here in the Question,
The frequency of the waves can be calculated using the formula:
frequency = number of waves/time
In this case, the number of waves is 12 and the time is 4 seconds. Substituting these values into the formula, we get:
frequency = 12 waves / 4 seconds = 3 Hz
Therefore, the frequency of these waves is 3 Hz.

a student uses a spring to launch a marble vertically in the air. The mass of the marble is
0.02 kg and when the spring is stretched 0.08 m it exerts a force of 58 N. What is
the maximum height the marble can reach?
Answer:
the maximum height reached by the marble is 11.84 m.
Explanation:
Given;
mass of the marble, m = 0.02 kg
extension of the string, x = 0.08 m
force applied to the string, F = 58 N
Apply the principle of conservation of energy;
elastic potential energy = gravitational potential energy
¹/₂fx = mgh
[tex]h = \frac{Fx}{2mg} \\\\h = \frac{58 \ \times \ 0.08}{2 \ \times \ 0.02 \ \times \ 9.8} \\\\h = 11.84 \ m[/tex]
Therefore, the maximum height reached by the marble is 11.84 m.

What is the frequency of a wave traveling at 10 m/s with a wavelength of 2 m?
Answer:
5 Hz
Explanation:
Given:
Wave velocity ( v ) = 10 m / sec
wavelength ( λ ) = 2 m
We have to calculate Frequency ( f ) :
We know:
v = λ / t [ f = 1 / t ]
v = λ f
= > f = v / λ
Putting values here we get:
= > f = 10 / 2 Hz
= > f = 5 Hz
Hence, frequency of sound is 5 Hz.

Un avión vuela a 10000m de altura y otro a 33300 pies, si un pie equivale a 30.48cm ¿Cuál vuela a mayor altura?
Answer:
Avion A (10000 meters).
Explanation:
Deje que la altura de los aviones sea A y B respectivamente.
Dados los siguientes datos;
Altura A = 10000 metros
Altura B = 33300 pies
Para encontrar el avión que voló más alto, tendríamos que hacer alguna conversión de unidades.
Conversión:
Metros a centímetros;
1 metro = 100 cm
10000 metros = 100 * 10000 = 1.000.000 centímetros.
Por lo tanto, la altura A en cm = 1,000,000 centímetros
Pies a centímetros;
1 pie = 30,48 centímetros
33300 pies = 33300 * 30,48 = 1014984 centímetros.
Por lo tanto, la altura B en cm = 1014984 centímetros.
De los cálculos anteriores, podemos deducir que el avión A voló más alto.
