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.

I NEED THE RIGHT ANSWER ASAP IT NEEDS TO BE 100% ACCURATE NO LINKS!!! Which type of force will an object move towards?
1: weakest
2: net
3: balanced
4: strongest
this is a Science question
Answer:
Strongest
Explanation:
Weak forces do not possess significant strength to pull an object. Net forces is the sum of all forces acting on an object. Balanced forces cancel each other out to have no pull whatsoever. S
The graph in Figure 4.15 shows the position and time for two runners in a race. Who has the faster speed, Robin or Joel? Explain how to answer this question without doing calculations.
Answer:
Joel has the faster speed.
Explanation:
Joel has a steeper slope on the graph. The steeper a slope is, the faster speed will be. Therefore, Joel's slope is steeper which increases overall speed.
how are sound vibrations amplified in a vertebrate ear?
Answer:
by movement of the bones of the middle ear and by differences in the surface area of the eardrum versus the oval window.
Explanation:
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
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.

why is the pressure in the bottom of the pacific ocean much bigger than near the surface
Answer:
increase in hydrostatic pressure
Explanation:
he force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere .

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

The precision of a balance is ±0.02 g. The accepted value for a measurement is 26.86 g. Which measurement is in the accepted range?
26.02 g
26.82 g
26.87 g
26.90 g
Explanation:
The precision of a balance is ±0.02 g.
The accepted value for a measurement is 26.86 g.
The accepted range is: =[26.86-0.02, 26.86+0.02] = [26.84, 26.88]So,26.87 g is correct

Jonathan in his motorcycle is going 70 miles per hour. How long would he take to go to a city 200 miles away?
Answer:
28.57 hoursExplanation:
The time taken by the motorcycle to reach the city can be found by using the formula
[tex]t = \frac{d}{s} \\ [/tex]
d is the distance
s is the speed
From the question
d = 200 miles
s = 70 miles / hour
We have
[tex]t = \frac{200}{7} \\ = 28.571428 \\ [/tex]
We have the final answer as
28.57 hoursHope this helps you

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
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?
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."
What does Newton's Second Law state and what are the formulas used?
Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

atoms and molecules in matter are always_______
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.
