Answer:
Three lunar eclipses every year.
Explanation:
A lunar eclipse only occurs during a full Moon, when the Sun, Earth and Moon are all aligned. But despite the Moon only taking 29.5 days to orbit Earth and complete a cycle from full Moon to full Moon, there are only on average about three lunar eclipses every year.
Answer:
512
Explanation:
Given sequence:
1/8, 1/2, 2, ...
Unknown:
The 7th term of the geometric sequence = ?
Solution:
To solve this problem, we apply the formula below;
Sₙ = arⁿ⁻¹
a is the first term
r is the common ratio
n is the nth term
r = = = 4
Input the parameters and solve;
Sₙ = x 4⁷⁻¹
Sₙ = x 4⁶ = 512
Answer:
The DNA in bacteria exists as unpacked blobs.
The DNA in animals and plants are neatly packed.
<h3>EXPLAMATION :</h3>
I don't really have an explanation.
The DNA in animals and plants are neatly packed into chromosomes, whereas the DNA in bacteria exists as an unpacked blob in the cell
The answer would be:
<span>It's rate of gaining speed decreases.
The rate at which speed changes is called acceleration,
You can think of this problem as an inclined plane. But the angle of an inclined plane is constantly decreasing.
We know that on a frictionless inclined plane acceleration of an object is:
</span>
<span>Where g is the gravitational acceleration of the Earth and
is the angle of an inclined plane.
Using our analogy, the ball would start on an inclined plane with a 90-degree angle and that angle would continue to decrease to zero.
The sine function is 1 at 90 degrees and is equal to zero at 0 degrees. Since our acceleration is proportional to the sine, and sine function is decreasing with the angle, our acceleration is also decreasing.
