The distance from the Moon to Earth is 3.9 x 10^8 meters. What is the time required for a light ray to travel from the Moon to Earth?

Answers

Answer 1

Given what we know about the speed of light, we can confirm that a single ray of light would take 1.3 seconds to travel from the Moon to the Earth.

What is the Speed of Light?The speed of light, as the name suggests, is the speed at which light travels. It has a value of over 299 million meters per second.It is considered the fastest that it is possible to travel, nothing is known to travel faster than light.

Therefore, since the Moon sits at a distance of 390 million meters from the Earth, and the fact that light travels at approximately 300 million meters per second, we can confirm that light from the moon takes roughly 1.3 seconds to reach Earth.

you push on box g that is next to box h, causing both boxes to slide along the floor, as shown in the figure. the reaction force to your push is

Answers

The reaction force to your push is the push of box G against you.

Newton's third law states that:

For every action, there is an equal opposite reaction.

So if an object x pulls or pushes an object y with a certain force, object y also exerts an equal and opposite force on object x.

Now, if you should push box G with a certain force, box G will exert an equal opposite force on you.

Hence, the reaction force to your push is the push of box G against you.

If you wanted to find an element that
would react similarly to chlorine (CI),
where would you look and why?

Answers

Answer:  Fluorine (F) and chlorine (Cl) are two good choices.  See reasoning below.

Explanation:  Mendeleev arranged the elements in the periodic table in a manner that each group, or vertical column, contained elements that exhibited similar chemical properities.  He even reserved spaces for undiscovered elements when none of the known elements had properties similar to those above or below the known elements in a group.  An interesting event illustrates this property.  In December 2010, NASA announced an important new discovery that was to be broadcast on live TV, creating much speculation (e.g., UFO's are real and we'll see the aliens sequestered at Roswell!!!  I knew it.).  

The actual announcement:

"Dec. 2, 2010:  NASA-supported researchers have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism, which lives in California's Mono Lake, substitutes arsenic for phosphorus in the backbone of its DNA and other cellular components."

A look at the periodic table shows arsenic just below phosphorus, in the same group.   This was an unexpected find, but it might have been predicted with an understanding of how the elements are organized.  

Side note:  look how close silicon is to carbon.  Can there be a life form whose being is made up of silicon instead of carbon?  Sure . . . why not?  Maybe not on Earth, but . . . wait . . . did that marble statue just wink?

atoms and molecules in matter are always_______

Answers

I think atoms and molecules in matter are always in motion because of kinetic energy.

Answer:

in motion.

Explanation:

In chemistry, we often explain the states of matter in terms of the kinetic molecular theory (KMT). The word kinetic refers to motion and the kinetic molecular theory suggests that atoms and molecules are always in motion. The energy associated with this motion is termed kinetic energy.

Point out the following about solids: The particles (atoms or molecules) are attracted to each other. The particles (atoms or molecules) vibrate but do not move past one another. The solid retains its shape.

They are not always in motion. They are always in motion if and only if the temperature of the surroundings is greater than absolute zero ( 0 K ).

Not only are molecules really small but they are in constant motion. The motion is called “thermal motion” because it's caused by temperature. Increase the temperature around them and the molecules move faster.

A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of 11 m/s in a time of 28 s. The combined mass of the boat and trailer is 410 kg. The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car

Answers

The tension on the hitch that connects the trailer to the car is 160 N.

From the information provided;

Initial velocity = 0 m/s (the car started from rest)

Final velocity = 11 m/s

Time taken = 28 s

From the formula;

a = v - u/t

a = 11 - 0/28 = 0.39 ms-2

The force that acts on the trailer  = tension in the hitch that connects the trailer to the car

Force = mass × acceleration

Force = 410 kg × 0.39 ms-2

Force = 160 N

If an object falls far enough, it will reach terminal velocity. At this velocity, the force of air
resistance is equal to the force of gravity on the object. The forces on the falling object are
balanced. What will happen to the object and why?

Answers

Answer:

The object will contine to fall, but at a constant velocity.  There will be no more acceleration.

Explanation:  When the force of gravity is equal to the reverse force of air resistance, there will will be no net force on the falling obect.  F = ma, and F (net) = 0.  It will continue at the same speed until those forces become imbalanced again (such as when the force pushing up from the ground is greater than the force of gravity pulling it down).  The metric term for this sudden resistance is "crash/bang/clunk/yieouch."
