b.) slushy mixtures of liquid and ice.
c.) gaseous bodies from which some of the gas is pushed out by the sun to form a long tail.
d.) chunks of rock that are generally a few tens of kilometers in diameter.
??? i appreciate those that help!!! <3
p.s. this subject is astronomy it just doesnt have it as a subject option nor a science option....
Answer:
the answer is a) chunks of ice that begin to vaporized if they pass close to the sun
When you blow across the top of a
soda bottle, it acts like a closed
pipe. If the inside of the bottle is
0.150 m long, what is the
fundamental frequency you hear?
(Speed of sound = 343 m/s)
(Unit = Hz)
Answer:
572
Explanation:
Got it right on Acellus, you take the velocity and divide it by 4 times the length.
Number of protons are equal to the number of electrons
Explanation:
the no of proton of an element is found in the inner part of the orbital of an element along with the neutron ,also knowing that this two add up to give mass no an element
where neutron+proton=mass no=nucleon no,where proton= electron, unless it carries charges call ion

Tarzan is swinging back and forth
on a 6.25 m long vine. What is the
period of his oscillation?
(Unit = s)
Answer:
5.02s
Explanation:
I got it right in acellus :)
The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.
Calculation of the period:Since
Length L = 6.25 m
g = 9.8 m/s²
So,
T = 2π√(L/g)
T = 2π√(6.25 / 9.8)
T = 5.01 sec
Hence, The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.

how does the sun rise and set
a.earth orbit around the sun
b.The sun is center of solar system
c.earth rotates on it tilted axis and orbit around the sun at the same time
Answer:
c. earth rotates on it tilted axis and orbit around the sun at the same time
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun. Thus, this makes us to experience day and night (sun rise and sun set) due to the rotation of planet about its axis.
Hence, the sun rise and set because the earth rotates on it tilted axis and orbit around the sun at the same time
