The force of gravity increases with mass, but decreases with increasing distance between objects.
When the moon is waxing it means that the sunlit fraction we can see from earth is getting larger. when it is wanning, the sunlit fraction is getting smaller and even as the phases of the moon change the total amount of sunlight the moon gets remains the same. half the moon is always in sunlight just as half the earth is always in sunlight. but because the period of rotation for the moon is the same as its period of revolution, on earth we always see the same side of the moon. If you lived on the far side of the moon, you would see the sun for half of each lunar day, but you would never see the earth.
Answer:
4.9 x 10⁻⁴N
Explanation:
Given parameters:
Mass of the vertical strand of spiderweb = 5 x 10⁻⁵kg
Unknown:
Tension in the vertical strand = ?
Solution:
The tension is the vertical strand will be the weight of the strand.
Weight of strand = mg
m is the mass
g is the acceleration due to gravity = 9.8m/s²
Tension in the vertical strand = 5 x 10⁻⁵kg x 9.8m/s²
Tension in the vertical strand = 4.9 x 10⁻⁴N
Answer:
The answer is A.
Explanation:
To measure a temperature, you have degrees with Farenheight or Celsius. Meters are measured with a meter stick while grams and kilograms are measurments for weight.
Therefore, degrees Celsius is your answer.
Best of Luck to you!
Remember Dark Energy is repulsive, the more the faster the universe expands (indeed accelerates), so the faster it would cool down and increase its size, not the other way. Now, no one knows what it is. For instance, if Dark Energy would rather be some other geometric effect, it could have a different ending than just if it is a cosmological constant term. So far, though, all experimental data do not favor anything else that is not compatible with just a cosmological constant ... We'll need to wait few years (~10 years) to get to know much better this with missions and ground experiments that are undergoing or planned to be launched.
