A 1 kg apple and a 2 kg baseball are 2 m apart. What is the force of gravity between each fruit?
1 answer:
The force of gravity between the apple and the baseball is 3.335×10¯¹¹ N
The following data were obtained from the question given above:
Mass of apple (M₁) = 1 Kg
Mass of baseball (M₂) = 2 Kg
Distance apart (r) = 2 m
Gravitational constant (G) = 6.67×10¯¹¹ Nm²/Kg²
<h3>Force (F) =? </h3>The force of gravity between them can be obtained as follow:
Therefore, the force of gravity between them is 3.335×10¯¹¹ N

Person standing on A will hear the loudest sound
Explanation:
The intensity of a sound wave (which is proportional to the loudness of the sound) follows an inverse square law, which is:
where
I is the intensity of the wave
r is the distance from the source of the sound
This equation means that the intensity of the sound wave (and therefore, its loudness) is inversely proportional to the square of the distance from the source: therefore,
- As we get closer to the source of sound, the loudness increases
- As we move away from the source of sound, the loudness decreases
Therefore, the person that will hear the loudest sound is the one standing closer to the source, and therefore person A.
