a physical science textbook has a mass of 2.2 kg. If the textbook weighs 19.6 newtons on Venus, what is the strength of gravity
2 answers:
Answer:
The strength of gravity on Venus is 8.91m/s².
Explanation:
The strength of gravity on a planet is given by the following formula:
g = w/m
In which w is the weight, in newtons, and m is the mass, in kg.
In this problem, we have that:
Textbook weighs 19.6 newtons on Venus.
This means that
mass of 2.2 kg
So m = 2.2
What is the strength of gravity on that planet?
g = w/m = 19.6/2.2 = 8.91
The strength of gravity on Venus is 8.91m/s².

Answer: A- It would increase
Explanation:
According to the law of universal gravitation:
Where:
is the module of the attraction force exerted between both objects
is the universal gravitation constant.
and
are the masses of both objects
is the distance between both objects
As we can see, the gravity force is directly proportional to the mass of the bodies or objects and inversely proportional to the square of the distance that separates them.
In other words:
<h2>If we decrease the distance between both objects, the gravitational force between them will increase. </h2>
