Gravity is a force acting on a object
The answer is ”D”, “a higher frequency and a shorter wavelength.
Answer:
The tension on the clotheslines is 
Explanation:
The diagram illustrating this question is shown on the first uploaded image
From the question we are told that
The distance between the two poles is 
The mass tie to the middle of the clotheslines 
The length at which the clotheslines sags is 
Generally the weight due to gravity at the middle of the clotheslines is mathematically represented as
let the angle which the tension on the clotheslines makes with the horizontal be 
which mathematically evaluated using the SOHCAHTOA as follows
=> ![\theta = tan^{-1}[\frac{4}{6} ]](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20%20tan%5E%7B-1%7D%5B%5Cfrac%7B4%7D%7B6%7D%20%5D)
=> 
So the vertical component of this tension is mathematically represented a
Now at equilibrium the net horizontal force is zero which implies that
=> 
substituting values
substituting values
Answer:
Pushing force
Explanation:
You technically push a ball when kicking it.
<u>Question:
</u>
The law of conservation of mass follows from the concept that a. atoms are indivisible. b. atoms of different elements have different properties. c. matter is composed of atoms. d. atoms can be destroyed in chemical reactions.
<u>Answer:</u>
The law of conservation of mass follows from the concept that atoms are indivisible
<u>Explanation:
</u>
The law of conservation of mass tells that atoms in an object neither can be created nor be destroyed, but they can be transferred around and transformed into various particles. Also, it says that the total mass preceding the chemical reaction corresponds to the total mass after the chemical reaction.
In other words, the mass remains intact. Lavoisier formulated this law as a result of a combustion experiment in which he stated that the weight of his starting material - a glass jar, tin and air - was equal to the mass of the material produced - a glass jar, "Tin calcium" and the rest of the air.
The term "atom" arrives from the language of Greek and means indivisible, because atoms were thought to be the tiny things present in the universe and could not be divided. But not familiar that atom comprises with three particles: proton, neutron and electron- even tiny particles like quarks.
