Because china was in war, and her parents didn't have enough money for to go to school.
Answer:
Density of 127 I =
Also,
Explanation:
Given, the radius of a nucleus is given as
.
where,
- A is the mass number of the nucleus.
The density of the nucleus is defined as the mass of the nucleus M per unit volume V.
For the nucleus 127 I,
Mass, M =
Mass number, A = 127.
Therefore, the density of the 127 I nucleus is given by
On comparing with the density of the solid iodine,
First let’s pick one at random
Less than 5 percentile
That means they lined 100 kids up and less than 5% of them are that certain weight.
So if you apply this to every option you will see the answer is
A). Less than 5 percentile
Answer:
1.58 W
Explanation:
Since the sound spreads uniformly in all directions, it must be in a form of a circle with radius of 12 m. So the area of the circle is
From the intensity of the sound we can calculate the power at 12 m
Choice C.
That's when convection stops.
