8 is missing for the table
Answer: $900
Step-by-step explanation:
The simple interest is calculated using the formula:
(P × R × T)/100
where,
P = Principal = $3000
R = Rate = 6%
T = Time = 5 years
Simple Interest = (P × R × T)/100
= ($3000 × 6 × 5)/100
= 90000/100
= $900
Therefore, the simple interest is $900
Nitrogen Radius = 5.8 x 10⁻¹¹ m
Beryllium Radius = 1.12 x 10⁻¹⁰ m
Let's find the quotient of N/Be :
(5.8x10⁻¹¹)/(1.12x10⁻¹⁰). But 10⁻¹¹/10⁻¹⁰ = 10⁽⁻¹¹⁺¹⁰⁾ = 10⁻¹ = 1/10 = 0.1
→ (5.8/1.12).(0.1) = 0.58/1.12 = 0.518.
Conclusion: the radius of Be is almost double than the radius of N
