Answer:This also means that Mercury's surface gravity is 3.7 m/s2, which is the equivalent of 38% of Earth's gravity (0.38 g). This means that if you weighed 100 kg (220 lbs) on Earth, you would weigh 38 kg (84 lbs) on Mercury.
Explanation:
Omitting the 1 will not change the value of the number, but will change the units at the end of the problem
Explanation:
a. Average speed = distance / time
= 100 m / 70 s
= 1.43 m/s
b. Average displacement = displacement / time
= 0 m / 70 s
= 0 m/s
Distance is the length of the path traveled. Displacement is the difference between the final position and initial position.
Answer:
Gravitational force will be 16 times more.
Explanation:
we know;
Gravitational force (F) = (Gm1m2)/d^2
when mass of each is doubled and distance between them is halved;
F= (G2m1×2m2)/(d/2)^2
=(4Gm1m2)/(d^2/4)
=4×4(Gm1m2)/d^2
=16(Gm1m2)/d^2
=16F
Answer;
All the above
Explanation;
The element carbon is the most important chemical constituent of many organic matter, ranging from fossil fuels to complex molecules such as DNA and RNA, that control genetic reproduction in organisms.
This element is found stored in major sinks found on the earth;
- as organic molecules in living and dead organisms found in the biosphere;
- as the gas carbon dioxide in the atmosphere;
- as organic matter in soils;
- in the lithosphere as fossil fuels and sedimentary rock deposits in the oceans as dissolved atmospheric carbon dioxide and
- as calcium carbonate shells in marine organisms.
