A negative exponent means the number of the exponent divide by the number. The the radius of beryllium atom is larger than the radius of a nitrogen atom by two times.
Given information-
The radius of a nitrogen atom is meters.
The radius of a beryllium atom is meters
<h3>Negative exponents</h3>
A negative exponent means the number of the exponent divide by the number.
As the radius of the nitrogen atom is meters. Convert it in the power of negative exponent of 10.
Let the radius of the nitrogen is mm. Thus,
Now the base of the exponents of both the atoms are same. As the radius of the nitrogen atom is meters and the radius of the beryllium atom is . Thus the radius of beryllium atom is larger.
To calculate how many times, the radius of beryllium atom should be divided by the radius of a nitrogen atom. Thus,
Thus the the radius of beryllium atom is larger than the radius of a nitrogen atom by two times.

Answer:
The complement event would be: "No rain today"
Its probability would be 70%
Step-by-step explanation:
Given the event:
A= rain today
The probability of rain today is 30%
P(A)=30%=0.3
The complement event has all the values that are not included in the event.
The complement event would be:
A'= No rain today
The probability of a event is the subtraction between 1 and the complement event:
P(A')=1-P(A)
Then, the probability of the event "No rain today" will be:
P(A')=1-0.3=0.7=70%
