Answer:
4 m/s
Explanation:
Step 1: Given data
- Mass of the balloon (m): 400 kg
- Kinetic energy of the balloon (KE): 3200 J
Step 2: Calculate the velocity (v) of the balloon
The kinetic energy is the energy that the balloon has due to its movement. We can calculate the velocity of the balloon using the following expression.
v = √(2 × KE/m)
v = √(2 × 3200 J/400 kg) = 4 m/s

A positively charged ion, one that would be attracted to the cathode in electrolysis.
Answer: 1. No, I don't think so. 2. Weight is the force of gravity, which is different from mass. 3. m2 is a unit of distance. 4. 30 x 20 x 5 = 3000 cm3 = 3 L
Explanation:
Answer:
Average speed = 9.59 m/s
Explanation:
Given data:
Distance = 100 m
Time taken = 10.42 s
Average speed = ?
Solution:
Formula:
Average speed = distance covered / time taken
by putting values,
Average speed = 100 m / 10.42 s
Average speed = 9.59 m/s
