Answer:
Change in height of the object
Explanation:
Change in height of the object
Since ,
We know potential energy can be written as mgh where
P.E. = mgh
M = mass ,
g = gravity constant
h = height
Kinetic energy can be written as 0.5 mv²
So , the Potential energy = kinetic energy
Then ,
velocity of object = √2 gh
Since g is a constant ,
Hence ,
Height of object will determine the velocity.
Answer:
I am not understand bro a question
There are four quantum numbers: the n, l, m and ms. When the orbital is 2p, it means that n=2 and l = 1. The n number takes the whole number before the sub-orbitals. Then, the designation for the p orbital is l=1. Now, the possible values if m is a range from -l to l. H<em>ence, in this case, that would be: -1, 0, 1.</em>
Since the half life of the radioactive isotope is 4,000 years, after 4,000 years the amount of the isotope would decrease by half. (Hence the name, half life.) So, after 4,000 years, there would be half of the isotope left in the fossil.
