Sound: The more _______ a sound has, the _________ its volume is.

Answers
No you don't. After the sound is made, it has to travel
to your ears before you can hear it.
The speed of sound in air is about 340 meters per second.
That's about 760 miles per hour. That sounds awfully fast, but
it means that it takes sound almost 5 seconds to cover 1 mile.
Sometimes when you're outside, you might see a neighbor
down the street doing some carpentry outside his house, or
you may see some workers putting a new roof on a house nearby.
If you have this opportunity, watch their hammers carefully.
Light travels much much much much much faster than sound ...
about 874 thousand times as fast as sound. So you see things
just about as soon as they happen, but it takes the sound a while
to reach you. If the distance is about 34 meters (about 110 feet)
or more, then you can start to see the difference ... you'll see the
hammer hit, and then you'll hear it. The farther the distance is,
the longer the delay is.
The same thing happens at a baseball game when the batter
connects. Firstyou see the ball hit the bat and fly away, and
thenyou hear the CRACK !

The law of gravity is an example of a universal law because Gravity is a force that exists between any to masses in the universe.
What is Newton's law of gravitation?
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
where, F - Force,
g - gravitational constant,
m₁ - mass of the object 1
m₂ - mass of the object 2
r² - distance between the two masses.
Gravitational attraction is along a line joining the centers of mass of these two bodies. The magnitude of the force is the same on each, consistent with Newton’s third law.
So, The law of gravity is an example of a universal law because Gravity is a force that exists between any to masses in the universe.
Hence, Option D is the correct answer.

Answer:
Yeah like the other answer D and A are kinda the same but i would pick D :p
Explanation:
sliding friction
rolling friction
drag
Answers
Answer:
Drag friction.
Explanation:
If you have a solid object, go through air, it experiences drag because the air molecules push back a tiny bit. This drag is enhanced because in water, the molecules are more resistant than air, that's why if you try to run in knee deep water, you experience much more drag than when you are running with your legs out of the water.

Any atom which no longer has a neutral charge is called a(n) _______ .
atomic or ion
Answers
1. A pH scale measures how much acidic or basic a substance is. The pH scale usually ranges from 0 to 14. .... The pH scale would be, (0 - 14), I think. SO the second one for 1. :)
2. So, Since an automobile battery can explode or contain and cause a sulfuric acid burn. I'm thinking it would be thee 1st one for the 2nd! :) sulfuric acid
3. Electrochemical and electrolytic reduction cleaning processes, so.... they are the most common techniques utilized to halt, stabilize, and even reverse the oxidation of the metal. So Overall I think this would most-likely Be electrolysis.
4. Is 1, because, pH of 1 (e)
5.I am thinking this would Be ion. Because, an ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

Answer:
Tides are the rise and fall of sea levels. Tides occur due to the gravitational forces exerted on the Earth by moon, and to a lesser extent, the sun. That's why tides occur in ocean or sea.
