Answer: an element is a substance that is made up of only one kind of atom.

Molecule: they are formed ehrn teo or more atoms join together.

Compound: a compound is a substance that is formed when two or more elements combine chemically.

They are related to each other by they all formed when some rhing joins to them molecules are formed of atoms and elements are also formed of atom and compound is formed of elements

A meter rule balance on a knife headge at the 55cm mark wheb a mass of 40g from 995cm .find the mass of the meter rule.

umka2103 [35]

Answer:

Let the weight of the ruler be X.

Now X acts in the middle, so we have 55-50 = 50cm

Since left hand movement= right hand movement

X(55-50)=90(95-55)

5X= 90×40

X=320cm

Hence the weight of the ruler is 320g

A falling object is said to reach a constant velocity (terminal velocity)..

Lana71 [14]

C

Terminal velocity is the maximum velocity attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object.(Wikipedia)

A hummingbird flies 2.0 m along a straight path at a height of 5.3 m above the ground. Upon spotting a flower below, the humming

stepan [7]

To solve this problem we will apply the concepts of Pythagoras to find the net path. An easy way is to graph the path to trace the path, which resembles that of a right triangle. The information provided is equivalent to that of the two short sides of the triangle, so we will find the longest side by the Pythagorean theorem. In this way,

$OC = \sqrt{2^2+2.4^2}$

$OC = 3.12m$

Therefore the magnitude of the hummingbird’s total displacement is 3.12m
