Answer:
Cell Membrane
Explanation:
The cell membrane controls what goes in and out of a cell, and keeps it shape, much like a city limit.
The distance between Jupiter and the sun is 5.2 AU.
According to Kepler's third law, the square of the period of revolution of planets is proportional to the cube of their mean distances from the sun. From this; T^2 = r^3.
Now, we are told that the orbital period (T) is 11. 9 Earth years. We have to make the distance the subject of the formula.
r =T^2/3
r = (11.9)^2/3
r = 5.2 AU

Answer:
, it will sink
Explanation:
The density of an object is given by

where
m is the mass of the object
V is its volume
For the body in the problem, we have
m = 4 kg = 4000 g

Therefore, its density is

And the object will sink in water, because its density is larger than that of water, which is
. (an object sinks when its density is larger than that of water, otherwise it floats).
Some people just know it. Do you have a question?
For the question above, here is the equation to follow:
<span>F = mgsinα = Wsinα
=200 x 0.5 = 100 N
</span>OR
<span>Sin30 * 200N = 100 N
</span>
The asnwer is 100N. I hope this answer helps.
