If gravity did not affect a horizontally thrown ball, the ball would continue along its horizontal path indefinitely (assuming it is thrown in a vacuum so no other forces are acting on it).

If gravity had no effect on a ball after you threw it ... and there also
were no air to slow it down ... then the ball would continue traveling
in a straight line, in whatever direction you threw it.

That's the heart and soul of Newton's laws of motion ... any object
keeps moving at the same speed, and in a straight line in the same
direction, until a force acts on it to change its speed or direction.\

If you threw the ball horizontally, then it would keep moving in the
same direction you threw it. But don't forget: The Earth is not flat.
The Earth is a sphere. So, as the ball kept going farther and farther
in the same straight line, the Earth would curve away from it, and it
would look like the ball is getting farther and farther from the ground.

nevsk [136]

Answer:

(a) $fd=1.7058\times 10^{-5}\ L.hr^{-1}.cm(b) [tex]r=26.008\ cm$

Explanation:

(a)

Oxygen consumption rate of humans, $Q_h=14.5\ L.hr^{-1}$

area of human skin, $A_h=1.7\ m^2$

diffusion rate through skin of humans, $d=2\%\ of\ Q_h$

∴ $d=\frac{2}{100} \times 14.5$

$d=0.29\ L.hr^{-1}$

<u>Flux of diffusion rate, </u>

$fd=\frac{d}{A}$

$fd=\frac{0.29}{17000}$

$fd=1.7058\times 10^{-5}\ L.hr^{-1}.cm(b)Surface area for a spherical animal:[tex]A=4.\pi.r^2$

Diffusion flux rate for animal:

$fd=\frac{14.5}{A}$

$1.7058\times 10^{-5}=\frac{14.5}{4.\pi.r^2}$

$r=26.008\ cm$

Someone please help me

Basile [38]

Photosynthesis is the name given to the set of chemical reactions performed by plants to convert energy from the sun into chemical energy in the form of sugar. Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen. Many reactions occur, but the overall chemical reaction for photosynthesis is:

6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
So it would be C, I hope this helped! :)

Complete the paragraph to compare Uranus and Neptune.

kipiarov [429]

Answer:

Uranus and Neptun are outer planets od the Solar system, since they are located after the asteroid belt. All of these outer planets are much larger then the inner ones so they are called the "ice giants". The other reason for this name is that they are very far from the Sun, so their temperature is low. Another feature they have in common is their atmosphere which is composed of gases, including methane, which is responsible for their blue color, since methane absorbs red light. However Neptune is known for very fast winds and storms in its atmosphere which is responsible for its high activity and changes.

So, the blanks should be filled with:

Sun

methane

Neptune

outer planets
