A rock dropped on the moon will increase its speed from 0 m/s ( its starting speed when first dropped) to 4.9 m/s in about 3 seconds. What value do you calculate for the magnitude of the acceleration of gravity on the moon?

Answers

Answer:

Acceleration, a = 1.64 m/s²

Explanation:

It is given that,

A rock is dropped on the moon, its initial velocity u = 0 m/s

Its speed increases from 0 to 4.9 m/s, v = 4.9 m/s

Time taken, t = 3 seconds

We have to find the magnitude of the acceleration due to gravity on the moon. The magnitude of acceleration is given by :

Acceleration, a = rate of change of velocity

$a=(v-u)/(t)$

$a=(4.9\ m/s-0)/(3\ s)$

a = 1.64 m/s²

So, the value of acceleration of gravity on the moon is 1.64 m/s². Hence, this is the required solution.

Acceleration = (change in speed) divided by (time for the change).

From the figures given in the question, the acceleration is ( 49/3 ) =

16.33 m/sec2

There's no way that this is happening on the moon. That acceleration is about 67%

greater

than the acceleration of gravity on the earth's surface. It should be about 83%

less,

or about

1.63 m/sec

I see the problem now. The '49' in the question should be '

4.9

apex- 1.63 m/s2

Answers

I am: A) DNA

DNA is double-stranded molecule which is often also it's most known feature. Perhaps less known (depends on who you ask) are facts that it also has thymine and not uracil (uracil is found in RNA). It has four nitrogen bases and it contains deoxyribose sugar (another hint that it's DNA and not RNA).
