Why does earth have the youngest surface of all the terrestrial planets today?
Answers
Answer:
Its the biggest terrestrial planet as the result of the interior being not able to cool down that much.
its rotates rapidly
Explanation:
the earth planet is not close to the sun,which puts it in the advantage of not loosing water.

Answer:
The answer is 30 min
Explanation:
t = s/v
v = 70 m/min, s = 2100 m
t = 2100/70 = 30 min.

I saw three different objects fall to the ground…an acorn, a leaf, and a small stick. I wondered how and why they fell the way they did. The stick fell from the very top of the tree and seemed to almost “slow down” about half way down. The acorn got faster all the way to the ground. Yet the leaf would just float back and forth in a calm rhythm like motion.
Furthermore, I could see the moon sitting up in the sky just waiting to peak over the trees at dark.
How is it that all objects are apparently affected by the earth’s gravity but they seem to respond differently? If gravity is a force that affects all objects…shouldn’t all objects respond the same? Interesting Phenomenon huh….
Can you explain what is happening with each of these four objects (including the moon)?
Answers
Answer:
gravity effects only the mass of an object
Explanation:
an acorn is heavier that a stick and it's round shape gives it less wind resistance so gravity pulls it down faster. A stick vertical has little wind resistance but when rotated to when it is horizontal it has more resistance so it slows down but the the force of gravity is still as strong. A leaf has very little mass and it's shape provideds lots of wind resistance so it falls slower. The moon is not only effected by the earth's gravity it is also effected by the suns. It has its own gravity as well. with all these factors it stays in place and moves with the earth.

The speed are they moving at will be 0.5 m/sec.Law of conservation of momentum is applied.
What is the law of conservation of momentum?
According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.
The given data in the problem is;
(m₁) is the mass of 1st gilder= 0.40 kg
(u₁) is the initial velocity = 2 m/s
(m₂) is the mass of 2nd gilder = 1.20 kg
(u₂) is the initial velocity of 2nd gilder = 0 m/s
(v) is the velocity after collision =.?
According to the law of conservation of momentum;
Momentum before collision =Momentum after collision
Hence, the speed are they moving at will be 0.5 m/sec
To learn more about the law of conservation of momentum refer;
#SPJ2
m1*u1 + m2*u2 =m1*v1 + m2*v2
here u2=0 body at rest, v1=v2=v both interlock and move together
0..4*2+1.2*0 = 0.4*v+1.2*v
v= 0.8/1.6 = 0.5 m/sec
