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.

A 2 kg object is falling at 3 m/s at what rate is gravity working on the object
Answer:
6kgm/s
Explanation:
Let the rate of gravity be the momentum of the body
Momentum = mass * velocity
Given
Mass = 2kg
velocity = 3m/s
Momentum = 2 * 3
Momentum = 6kgm/s
Hence the rate at which the gravity is working is 6kgm/s

How do airplanes stay in air?
Answer:
A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. The wings force the air downward and that pushes the plane upward.
Explanation:
planes stay in air because of 2 reasons :
Power of thier enginesAerodynamicsPlane's wings are designed to push the air downwards and letting the plane to lift off and stay in air..
At the base of a hill, a 90 kg cart drives at 13 m/s toward it then lifts off the accelerator pedal). If the cart just barely makes it to the top of this hill and stops, how high must the hill be?
Answer:
the height of the hill is 8.622 m.
Explanation:
Given;
mass of the cart, m = 90 kg
speed of the cart at the base, v = 13 m/s
Let the height of the hill = h
Apply the principle of conservation of energy, to determine the height of the hill.
¹/₂mv² = mgh
¹/₂v² = gh
[tex]h= \frac{1}{2} \times \frac{v^2}{g} \\\\h = \frac{1}{2} \times \frac{13^2}{9.8} \\\\h = 8.622 \ m[/tex]
Therefore, the height of the hill is 8.622 m.

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.

A printer has a power of 100 W. It takes 30 seconds to print out a document. How much energy will it
have used?
100W translates to 100 watts consumed in 1 hour. Assuming the printer consumes electrical energy at a steady rate, then: 100 ÷ 60 = 1.6667 watts per minute. 1.6667 ÷ 2 = 0.8333 watts consumed in 30 seconds.
A printer has power of 100 W, and it takes time of 30 seconds to print out the document, then the power consumed in 30 seconds will be 0.8333 W.
What is Power?The quantity of energy moved or changed per unit of time is termed as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in historical texts. A scalar quantity is power.
Power is connected to other factors; for instance, the power required to move a land vehicle is equivalent to the sum of the vehicle's velocity, traction force on its wheels, and aerodynamic drag.
Assuming the printer consumes electrical energy at a steady rate, then:
100 ÷ 60 = 1.6667 watts per minute.
Now, calculate the power consumed in 30 seconds,
1.6667 ÷ 2 = 0.8333 watts.
Therefore, the power consumed in 30 seconds will be 0.8333 watts.

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)

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)."

Someone fires a 0.04 kg bullet at a block of wood that has a mass of 0.5 kg. (The block of wood is sitting on a frictionless surface, so it moves freely when the bullet hits it). The wood block is initially at rest. The bullet is traveling 300 m/s when it hits the wood block and sticks inside it. Now the bullet and the wood block move together as one object. How fast are they traveling?
Answer:
Explanation:
Remark
This is a conservation problem.
The momentum before impact = momentum after impact
momentum before
m = 0.04 kg
v = 300 m/s
momentum after
m = 0.5 kg + 0.04kg That's the mass of the block and bullet
v = ?
Solution
0.04 * 300 = 0.54 * x
12 kg m/s = 0.54 kg * x
12 / 0.54 = x
x = 22.22 m/s
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

(ii) Calculate the force required to accelerate a mass of 60 kg at 2.5m/s2
force =
[2]
Answer:
Force = 150 Newton.
Explanation:
Given the following data;
Mass = 60kg
Acceleration = 2.5m/s²
To find the force;
Force = mass * acceleration
Force = 60 * 2.5
Force = 150 Newton.
Therefore, the force required to accelerate this mass is 150 Newton.

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
