Answer:
![388 cm^3](https://tex.z-dn.net/?f=388%20cm%5E3)
Explanation:
For this problem, we can use Boyle's law, which states that for a gas at constant temperature, the product between pressure and volume remains constant:
![pV=const.](https://tex.z-dn.net/?f=pV%3Dconst.)
which can also be rewritten as
![p_1 V_1 = p_2 V_2](https://tex.z-dn.net/?f=p_1%20V_1%20%3D%20p_2%20V_2)
In our case, we have:
is the initial pressure
is the initial volume
is the final pressure
Solving for V2, we find the final volume:
![v_2 = \frac{p_1 V_1}{p_2}=\frac{(75.9)(639)}{125}=388 cm^3](https://tex.z-dn.net/?f=v_2%20%3D%20%5Cfrac%7Bp_1%20V_1%7D%7Bp_2%7D%3D%5Cfrac%7B%2875.9%29%28639%29%7D%7B125%7D%3D388%20cm%5E3)
OK so yeah the mercury Venus Earth and Mars a rocky planets and Jupiter Saturn Uranus and Neptune our gaseous planets so I think that’s your answer correct me if I’m wrong:D
Answer:
t = 8.45 sec
car distance d = 132.09 m
bike distance d = 157.08 m
Explanation:
GIVEN :
motorcycle is 25 m behind the car , therefore distance need to covered by bike to overtake car is 25+ d, when car reache distance d at time t
for car
by equation of motion
![d = ut + \frac{1}{2}at^2](https://tex.z-dn.net/?f=d%20%20%3D%20ut%20%2B%20%5Cfrac%7B1%7D%7B2%7Dat%5E2)
u = 0 starting from rest
![d = \frac{1}{2}at^2](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%7D%7B2%7Dat%5E2)
![t^2 = \frac{2d}{a}](https://tex.z-dn.net/?f=t%5E2%20%3D%20%5Cfrac%7B2d%7D%7Ba%7D)
for bike
![d+25 = 0 + \frac{1}{2}*4.40t^2](https://tex.z-dn.net/?f=d%2B25%20%3D%200%20%2B%20%5Cfrac%7B1%7D%7B2%7D%2A4.40t%5E2)
![t^2= \frac{d+25}{2.20}](https://tex.z-dn.net/?f=t%5E2%3D%20%5Cfrac%7Bd%2B25%7D%7B2.20%7D)
equating time of both
![\frac{2d}{a} = \frac{d+25}{2.20}](https://tex.z-dn.net/?f=%5Cfrac%7B2d%7D%7Ba%7D%20%3D%20%5Cfrac%7Bd%2B25%7D%7B2.20%7D)
solving for d we get
d = 132 m
therefore t is![= \sqrt{\frac{2d}{a}}](https://tex.z-dn.net/?f=%20%3D%20%5Csqrt%7B%5Cfrac%7B2d%7D%7Ba%7D%7D)
![t = \sqrt{\frac{2*132}{3.70}}](https://tex.z-dn.net/?f=t%20%3D%20%20%5Csqrt%7B%5Cfrac%7B2%2A132%7D%7B3.70%7D%7D)
t = 8.45 sec
each travelled in time 8.45 sec as
for car
![d = \frac{1}{2}*3.70 *8.45^2](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A3.70%20%2A8.45%5E2)
d = 132.09 m
fro bike
![d = \frac{1}{2}*4.40 *8.45^2](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A4.40%20%2A8.45%5E2)
d = 157.08 m
Answer:
Contemporary light microscopes are able to magnify objects up to about a thousand times. Since most cells are between 1 and 100 μm in diameter, they can be observed by light microscopy, as can some of the larger subcellular organelles, such as nuclei, chloroplasts, and mitochondria.
A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.
Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.
If the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.
