Un cuerpo de 480 g de masa es atraído con una fuerza de 3.9 E-6 N por otro cuerpo de 196 g de masa. Calcula la distancia a la que se encuentran.
Answer:
La distancia entre los dos cuerpos es aproximadamente 1.269 milímetros.
Explanation:
Asumamos que ambos cuerpos son partículas, la fuerza de atracción ([tex]F[/tex]), en newtons, entre ambos cuerpos se define mediante la Ley de Newton de la Gravitación Universal, cuya ecuación es:
[tex]F = G \cdot \frac{m_{1}\cdot m_{2}}{r^{2}}[/tex] (1)
Donde:
[tex]G[/tex] - Constante de la gravitación universal, en metros cúbicos por kilogramo-segundo cuadrado.
[tex]m_{1}, m_{2}[/tex] - Masas de los cuerpos, en kilogramos.
[tex]r[/tex] - Distancia entre los cuerpos, en metros.
Si sabemos que [tex]G = 6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}}[/tex], [tex]m_{1} = 0.48\,kg[/tex], [tex]m_{2} = 0.196\,kg[/tex] y [tex]F = 3.9\times 10^{-6}\,N[/tex], entonces la distancia entre los dos cuerpos es:
[tex]r = \sqrt{\frac{G\cdot m_{1}\cdot m_{2}}{F} }[/tex]
[tex]r \approx 1.269\times 10^{-3}\,m[/tex]
Es decir, la distancia entre los dos cuerpos es aproximadamente 1.269 milímetros.
What causes seafloor spreading, subduction, and the movement of
tectonic plates?
Answer:
Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth's mantle. Seafloor spreading creates new crust.

Answer:
thermal energy
Explanation:
heat transfers into it causing it to physically change
Answer:
A pesar de las diferencias entre cada copo de nieve y las grandes familias de copos que existen, estos todavía tienen una base hexagonal. Esta estructura hexagonal se explica por la forma en que las moléculas de agua se unen para formar un cristal
Despite the differences between each snowflake and the large families of flakes that exist, they still have a hexagonal base. This hexagonal structure is explained by the way in which water molecules come together to form a crystal.

Answer:
4. Force = 178.6 Newton.
5. Acceleration = 2.28 m/s².
6. Force = 178.6 Newton.
Explanation:
4. Given the following data;
Acceleration = 3.8 m/s²
Mass = 47kg
Force = mass * acceleration
Force = 47 * 3.8
Force = 178.6 Newton.
5. Given the following data;
Force = 785N
Mass = 345kg
Acceleration = force/mass
Acceleration = 785/345
Acceleration = 2.28 m/s²
6. Given the following data;
Acceleration = 6m/s²
Force = 32N
Mass =force/acceleration
Mass = 32/6
Mass = 5.33 kilograms

"Influence" between bodies is reduced as the bodies are: brought closer moved farther apart increased in charge held stationary
Answer:
moved farther apart
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
"Influence" between bodies is reduced as the bodies are moved farther apart based on Newton's law of universal gravitation.
Newton's law of universal gravitation states that the force of attraction (gravity) acting between the Earth and all physical objects is directly proportional to the Earth's mass, directly proportional to the physical object's mass and inversely proportional to the square of the distance separating the Earth's center and that physical object.
Ralston had lots of spicy and oily food which triggered heartburn. The doctor prescribed
him Milk of Magnesia.
a. Why did the doctor prescribe milk of magnesia?
b. What is the chemical name of milk of magnesia?
Answer:
A.) The doctor decided to prescribe milk of magnesia because of the mineral Magnesium. Magnesium helps to reduce stomach acid and increases the water in the intestines which helps induce motility in the intestines. Heartburn is caused by stomach acids traveling up into your esophagus which causes that feeling of your heart burning. Milk of magnesia will help soothe this.
B.) The chemical name of milk of magnesia is magnesium hydroxide.
Explanation:
The chemical name of the milk of magnesia is magnesium hydroxide.
An antacid is any substance that is taken to decrease or neutralize the acidity of the gastro intestinal tract. We must note that the gastrointestinal tract is natural acidic.
However, hyperacidity of the gastrointestinal tract could lead to heartburn. This acidity is neutralized using an antacid such as milk of magnesia. The chemical name of the milk of magnesia is magnesium hydroxide.

4. Un móvil lleva una velocidad de 75 m/s, en dicho momento aplica los frenos durante tiempo de 15 segundos hasta detenerse. ¿cuál será la aceleración del frenado? ¿cuál es la distancia que recorre hasta detenerse?
Answer:
a = 5 m / s² and x = 562.5 m
Explanation:
Let's apply the kinematics relations
v = v₀ + at
v² = v₀² + 2a x
In this case, as the car stops, its final speed is zero (v = 0) and the acceleration must be opposite to the speed, that is, negative
0 = v₀ - a t
a = v₀ / t
let's calculate
a = 75/15
a = 5 m / s²
let's look for the distance
0 = v₀² - 2a x
x = v₀² / 2a
let's calculate
x = [tex]\frac{75^2}{2 \ 5 }[/tex]
x = 562.5 m

Both rotate in the same direction.
Both have ample water on their surfaces.
Both have a solid inner core and a liquid outer core.
Answer: D
Explanation: I have my answers VS. Go0gle answers (go0gle answers are pics)
(A) Both have the same day length. Well, Venus doesn't havve the same amount of days. (I already know off the top of my head, but I still searched it up)
(B) Both rotate in the same direction. In school (before Virus) they would always show diagrams of the planets on the projector and Venus doesn't rotate
(C) Both have ample water. No. Venus doesn't have much water >_>
(D) Both have a solid inner core and a liquid outer core. Yesh. In my lessons (before), Venus has a solid inner core and liquid outer core.
If the distance between 2 charged particles is double, the force between them changes by a factor of?
Answer:
See explanation
Explanation:
Given that;
q1 and q2 are the magnitudes of the two charges while r1 is the distance between the charges.
F1 =kq1q2/r1^2
Then,
F2 = kq1q2/(2r1)^2
F2 = kq1q2/4r1^2
So,
F2 = 1/4 F1
The force between the charges changes by a factor of 1/4.
Calculate the charge that flows through the cell in 1 minute. Each filament lamp has a power of 3 W and a resistance of 12 Ω
Answer:
24 Coulumbs
Explanation:
Given data
time= 1 minute= 6 seconds
P=2 W
R= 12 ohm
We know that
P= I^2R
P/R= I^2
2/12= I^2
I^2= 0.166
I= √0.166
I= 0.4 amps
We know also that
Q= It
substitute
Q= 0.4*60
Q= 24 Columbs
Hence the charge is 24 Coulumbs

If the amount of force from the group on the left was 235 N, what is the amount of force from the group on the right
Answer:
(F = ma ) Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration.
A person runs 2 laps around a 400 meter track and stops where they initially
began running. It took this person 3 minutes and 18 seconds to complete this
run. What is this persons average velocity?
A:4.04 m/s
B:2.02 m/s
c:0 m/s
The runner's total distance covered was 800 meters. Her displacement (straight-line distance between start-point and end-point) was zero.
Her average speed = (distance)/(time) = 4.04 m/s
Her average velocity = (displacement) / (time) = zero (choice - c)
