Answer:
Fj / Fe = 24.5 / 9.8 acceleration on Jupiter / acceleration on Earth
Fj / Fe = 2.5
Fj / Fe = 2.5 force on Jupiter = 2.5 that on Earth
W = F = M a
W Jupiter) = 5 kg * 9.8 m/s^2 * 2.5 = 122.5 N
or more simply
F = M a = 5 kg * 24.5 m/s^2 = 2=122.5 N
Calculate the amount of force required to produce motion in a car of 1000kg with an acceleration of 5m/s square.
Answer:
5000 N
Explanation:
F=ma
=1000*5
=5000N
Here's the solution,
mass = 1000 kgacceleration = 5 m/s²now, we know
[tex] \large \boxed{f = m \times a}[/tex]
so,
[tex] \hookrightarrow \: f = 1000 \times 5[/tex][tex] \hookrightarrow \: f = 5000[/tex]The force required is 5000 Newtons.

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----
If you increase the amount of spinach you eat, then you will increase the iron in your blood. What's the dependent variable?
The quantity of iron in your blood is the dependent variable because it is influenced by how much spinach you consume. The amount of spinach you consume will act as the independent variable because it doesn't require iron in any way.
What is the dependent variable?A dependent variable is one whose values can be determined by testing in a scientific experiment. It is clear that the dependent variable depends on the independent variable. While a result, we can now see and note changes in the dependent variable as the experimenter modifies the independent variable.
Given:
Increase the amount of spinach you eat, then you will increase the iron in your blood,
Write the equation for the above phrase as shown below,
The amount of iron = variable × the amount of spinach
y = ax
here, y is The amount of iron and x is the amount of spinach
Thus, the dependent variable is the quantity of iron.

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.

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.

A 100 kg cyclist travels at 4.5 m/s. A 50 kg gorilla is dropped straight down onto her. What is the new speed of the system?
Mass of cyclist = 100 kg
Mass of gorilla = 50 kg
Initial speed = 4.5 m/s
Let Final speed = s
100 x 4.5 = (100 + 50) x s
450 = 150s
S = 450/150
S = 3
The new speed is 3m/s
If a 50 kg person is running at a rate of 2 m/s, the person’s momentum is
_____________ kg • m/s.
The period of a wave is 20 ms (milliseconds) and its wavelength is 4 cm. Calculate:
a) The frequency of the wave
b) The velocity of the wave.
Answer:
A. 50 Hz
B. 2 m/s
Explanation:
We'll begin by converting 20 ms to s. This can be obtained as follow:
1000 ms = 1 s
Therefore,
20 ms = 20 ms × 1 s / 1000 ms
20 ms = 0.02 s
Next, we shall convert the value of the wavelength (i.e 4cm) to m. This can be obtained as follow:
100 cm = 1 m
Therefore,
4 cm = 4 cm × 1 m / 100 cm
4 cm = 0.04 m
A. Determination of the frequency.
Period (T) = 0.02 s
Frequency (f) =?
f = 1 / T
f = 1 / 0.02
f = 50 Hz
Therefore, the frequency of the wave is 50 Hz
B. Determination of the velocity.
Wavelength (λ) = 0.04 m
Frequency (f) = 50 Hz
Velocity (v) =?
v = λf
V = 0.04 × 50
v = 2 m/s
Therefore, the velocity of the wave is 2 m/s

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.

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.
