So, the force of gravity that the asteroid and the planet have on each other approximately
<h3>Introduction</h3>
Hi ! Now, I will help to discuss about the gravitational force between two objects. The force of gravity is not affected by the radius of an object, but radius between two object. Moreover, if the object is a planet, the radius of the planet is only to calculate the "gravitational acceleration" on the planet itself,does not determine the gravitational force between the two planets. For the gravitational force between two objects, it can be calculated using the following formula :
With the following condition :
- F = gravitational force (N)
- G = gravity constant ≈ N.m²/kg²
- = mass of the first object (kg)
- = mass of the second object (kg)
- r = distance between two objects (m)
<h3>Problem Solving</h3>
We know that :
- G = gravity constant ≈ N.m²/kg²
- = mass of the planet X = kg.
- = mass of the planet Y = kg.
- r = distance between two objects = m.
What was asked :
- F = gravitational force = ... N
Step by step :
<h3>Conclusion</h3>
So, the force of gravity that the asteroid and the planet have on each other approximately

lanation:
Answer:
The sound travels differently in different medium according the density of the medium.
Explanation:
The sound travels faster in dense medium and can be heard by the vibration of the bone present in the ear. The ear plugs reduce the sound intensity in both medium water and on land (air).
In air the sound is not heard properly due to the earplugs that stops the as the vibration are not able to produce as sound is not able to reach to middle ear, but Navy researchers have discovered that sound under water is heard by the bone present behind the ear, vibrations mastoid.
Answer:
The average net force on the truck is 375 Newtons.
Explanation:
Using Newton's 3rd equation of motion, we have :
×a×s
where, v = final velocity = 25 m/s
u = initial velocity = 20 m/s
a = acceleration
s = distance traveled = 300 m
Using these values in the above equation, we get acceleration = 0.375 m/
Using Newton's second law, we have:
F=m×a
where m = mass = 1000 kg
a= acceleration = 0.375 m/
Putting values we have F=375 N
