The atmosphere is composed of 5 layers which is 500 kilometers above the ground. This are Troposphere, Stratosphere, Mesoshpere, Thermosphere, and Exosphere. After the Exosphere is the outer bounderies which is the space
Answer:
0.2 m
Explanation:
Diameter = 0.3 m
radius, r = 0.15 m
Length, H = 0.4 m
density of wood, d = 0.5 g/cm^3 = 500 kg/m^3
density of water, d = 1000 kg/m^3
Let h be the depth of cylinder immersed in water.
By the principle of floatation.
Buoyant force = Weight of cylinder
Volume immeresed x density of water x g = Volume of cylinder x density of wood x g
A x h x 1000 x g = A x H x 500 x g
1000 h = 500 x 0.4
h = 0.2 m

<span>The relative hardness of a mineral
can be tested by the Moh’s scale or the mineral hardness. The Moh’s scale can
be characterized by the ability of the mineral to resist scratch resistance by
scratching a harder or softer mineral. It has a scale of 1 to 10 where 1 being
the softest and 10 being the hardest. The relative hardness of a mineral can
best be tested by scratching the mineral across a glass plate. The answer is
letter A. </span>
Answer:
I guess that we want to find how much money you get each week.
We know that the job pays $8.60 per hour.
We know that you work 20 hours per week.
Then the gross pay (the total money that you earn) in a week is 20 times $8.60, or:
20*$8.60 = $172.
Now we know that your employer witholds:
10% + 7.65% + 5% = 22.65%
Then your employer withholds 22.65% of your gross pay.
if the 100% of your gross pay is $172
Then the 22.65% will be:
(22.65%/100%)*$172 = 0.2265*$172 = $38.96
This means that your employer withholds $38.96 of your weekly gross pay.
Then each week you get:
$172 - $38.96 = $133.04
