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.
A car is traveling at 10 m/s. 10 seconds later the car is traveling 40 m/s. What is the car’s acceleration?
Answer:
a = 3 m/s^2
Explanation:
Vi = 10 m/s
Vf = 40 m/s
t = 10 s
Plug those values into the following equation:
Vf = Vi + at
40 = 10 + 10a
---> a = 3 m/s^2
The car is traveling with an initial velocity of 10 m/s, a final velocity of 40 m/s in the time period of 10 seconds, then the acceleration of the car is 3 m/s².
What is acceleration?Acceleration describes a change in an object's velocity. By accelerating, decelerating, or changing direction of motion, an object's velocity may change.
An apple falling to the ground, the moon orbiting the earth, and a car stopping at a set of traffic lights are a few examples of acceleration. With the aid of these illustrations, we may better see that acceleration occurs whenever a moving object modifies its direction, speed, or both.
The given values according to the question are,
Initial velocity, u = 10 m/s
Final velocity, v = 40 m/s and,
Time, t = 10 seconds.
Use the equation of motion to find the acceleration,
v = u + at
40 = 10 + (a)10
a = 30/10
a = 3 m/s².
Hence, the acceleration of the car is 3 m/s².

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

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.

If my angular velocity slows from 30 Hz to 20 Hz in 72°, what is my deceleration?
Answer:
The deceleration is -7.85x10³ rad/s².
Explanation:
The angular speed (ω) is related to frequency (f) as follows:
[tex] \omega = 2\pi f [/tex]
When the frequency is 30 Hz the angular speed is:
[tex] \omega_{i} = 2\pi f = 2\pi*30 Hz = 188.5 rad/s [/tex]
Now, when the frequency is 20 Hz the angular speed is:
[tex] \omega_{f} = 2\pi*20 Hz = 125.7 rad/s [/tex]
Finally, the angular acceleration (α) can be found using the following equation:
[tex] \omega_{f}^{2} = \omega_{i}^{2} + 2\theta \alpha [/tex]
Where:
θ: is the angular displacement = 72°
[tex] \alpha = \frac{\omega_{f}^{2} - \omega_{i}^{2}}{2\theta} [/tex]
[tex] \alpha = \frac{(125.7 rad/s)^{2} - (188.5 rad/s)^{2}}{2*72*\frac{2\pi rad}{360}} = -7.85 \cdot 10^{3} rad/s^{2} [/tex]
Therefore, the deceleration is -7.85x10³ rad/s².

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

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.

Plssssss help me no one wants to help me——— power plants use generators to generate electricity for homes and businesses. Some generators work by spinning a coil of wire inside a magnet, as shown in the image. To keep the coil of wire spinning, it’s often attached to a turbine, which is s as n axle with fan blades. Different kinds of power plants use different methods to spin the turbine to make electricity. What’s one way a power plant might spin the turbine?
Answer:
There are a many ways to produce electricity. Electrons can flow between certain different materials providing a current, as in a common battery. While reliable and portable, chemical batteries run down quickly. To provide the large amounts of steady power demanded by modern societies, large power plants have been built. Most power plants make electricity with a machine called a generator.
A 1925 Turbine Rotor
A 1925 turbine rotor for a Westinghouse generator, Image #21.035, Science Service Historical Image Collection, National Museum of American History
Generators have two important parts: the rotor (which rotates) and the stator (which remains stationary). Generators use the principle of electro-magnetic induction, which exploits the relation between magnetism and electricity. In large AC generators, an outer shell with powerful magnets rotates around a stationary "armature" which is wound with heavy wire. As they move, the magnets induce an electric current in the wire.
It is important to recognize that electricity is not mined or harvested, it must be manufactured. And since it's not easily stored in quantity, it must be manufactured at time of demand. Electricity is a form of energy, but not an energy source. Different generating plants harness different energy sources to make electric power. The two most common types are "Thermal Plants" and "Kinetic Plants".

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)."
