The volume of water in the larger balloon is 8 times greater than in the smaller balloon
We'll begin by calculating the volume of each balloon.
<h3>For smaller balloon:</h3>
- Radius (r) = 3 cm
- Pi (π) = 3.14
- Volume (V) =?
V = 4/3 πr³
V = 4/3 × 3.14 × 3³
<h3>V = 113.04 cm³</h3>
<h3>For larger balloon:</h3>
- Radius (r) = 6 cm
- Pi (π) = 3.14
- Volume (V) =?
V = 4/3 πr³
V = 4/3 × 3.14 × 6³
<h3>V = 904.32 cm³</h3>
Finally, we shall determine how much greater the larger balloon is to the smaller balloon
- Volume of smaller balloon = 113.04 cm³
- Volume of larger balloon = 904.32 cm³
- Greatness =?
Greatness => large / small
Large / small = 904.32 / 113.04
Large / small = 8
Cross multiply
<h3>Large = 8 × small </h3>
Therefore, the larger balloon is 8 times greater than the smaller balloon.

Answer:
Pendulum B
Explanation:
The time period of a pendulum is given by :
Case 1.
Mass, m = 200 g = 0.2 kg
Length of string, l = 1 m
Time, 
T₁ = 2.007 Seconds
Since, 
f₁ = 0.49 Hz
Case 2.
Mass, m = 400 g = 0.4 kg
Length of string, l = 0.5 m
Time, 
T₂ = 1.41 seconds
f₂ = 0.709 seconds
Hence, pendulum B have highest frequency of vibration.
We are asked to determine the length of the second hand when it has moved 2 cm in 15 seconds. The movement in 15 seconds generates an angle of 90 degrees or pi / 2. we apply the equation of arc length which is 2 cm; s = 2= r theta = r* pi /2 where r is the second hand length. The answer is 1.27 cm closest to A
