Answer: They will repel each other.
Explanation:
Two inflated balloons when rubbed with woolen cloth will lead to repeal each other because of the similar charges on both the balloons.
Rubbing both the balloons together by the woolen cloth will introduce negative charge in the balloons.
As, we know that the same charges repeal each other both of the balloons with be apart from each other.
This is due to the static electricity, the negatively charged particles jump to the positive one. When balloons are rubbed they become negatively charged.
The mass of an object is the same on Earth, in orbit, or on the surface of the Moon. Units of Force. The equation.
The expected time period between the observations of lightning and thunder would be 22.5 s.
How to calculate the time of sound waves?
The time taken by sound to reach a certain position can be calculated by the speed formula,

Where,
- speed = 0.343 km/s
- distance = 7.5 km
- time = ?
Put the values in the formula,

Therefore, the expected time period between the observations of lightning and thunder would be 22.5 s.

The question above is simply a conversion problem. We are asked to convert from Celsius to Fahrenheit and to Kelvin. To convert from Celsius to Fahrenheit, we do as follows:
°F = (°C<span> × </span>9/5) + 32
°F = (30 × 9/5) + 32
°F = 86
From Celsius to Kelvin,
K = °C + 273.15
K = 30 + 273.15 = 303.15
