Answer:
304 K
Explanation:
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.
How is Venus similar to Earth?
Both have the same day length.
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.

what are the comparisons and contrast of adaptation and natural selection? ASAP!!!!!!
Answer:
Natural selection is a mechanism, or cause, of evolution.
Explanation:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
City A is much larger than city B, but they are located at the same latitude and elevation. However, city A is receiving more rainfall than city B. Given this information, which statement most likely explains why?
Answer:
City A has more large buildings than city B, which force more air upward into the atmosphere.
Explanation:
The statement which most likely explains why city A is receiving more rainfall than city B despite its larger area is because "City A has more large buildings than city B, which force more air upward into the atmosphere."
This is evident in the fact that city A's large buildings contribute a stream of lift to raise warm, moist, surface air into the humid air right over the area, where it then transformed into rain clouds.

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.

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)

write the relation between horsepower and Watt?
Explanation:
Horsepower is related to watt as: 1 horsepower = 746 W = 750 W approximately. 1 horsepower (HP) = 750 watt (approx.) The power is one watt when one joule of work is done in one second.
Answer:
1HP = 746 watts
Explanation:
The relation between Horsepower and watt is that One Horse Power is equal to 746 Watts .
[tex]\large{\boxed{ \sf 1 HP = 746 Watts = 0.746 kW }}[/tex]

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 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.

Assume ω = 47.0 rad/s . What is the magnitude v of the velocity of the particle in m/s?
That completely depends on the radius of the particle's path.
That is, the radius of the wheel the particle is riding on, and exactly where on the wheel the particle is riding.
This information is not included in the question, so no answer is possible.
"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.

Which quantity is most closely related to the speed of gas particles? (2 points)
A The temperature of the gas
B The number of molecules in the gas
C The density of the gas
D The total volume of the gas
Quantity is most closely related to the speed of gas particles is the temperature of the gas.
Specifically, the speed of the molecules in a gas is dependent on its temperature (the higher the temperature the faster the gas molecules move). Another way to think of it is that the temperature of a gas is a measure of the average kinetic energy of that gas.
What is temperature ?"Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature)."

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
