Answer:
The electrical force of attraction between the balloons is 
.
Explanation:
Given that,
Charge 1, 
Charge 2, 
Distance between the charges, d = 0.65 m
We need to find the electrical force of attraction between two balloons. It is given by the formula as :
So, the electrical force of attraction between the balloons is . Hence, this is the required solution.
Answer:
= 53.4 m/s
Explanation:
Velocity of a sound is given by the formula;
Velocity = Frequency × 2 (Length)
Frequency = 30 Hz
Length = 89 cm, equivalent to 0.89 M
Therefore;
Velocity = 30 × 2 ×0.89
= 53.4 m/s
Thus; the velocity or the speed of sound is 53.4 m/s
