A plane mirror forms an image of an object because it ____________ light from the object.

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.

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.

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.

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

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.

i had the question

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.

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.

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

this might be wrong. I am just in jss2 but I read physics

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.

"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)."

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.
