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>
Gravity lets all objects fall to the ground at the same speed, 9.8 m/s/s. If the force of gravity were stronger, such as 10 m/s/s, the rate of acceleration would be faster.
Answer:
The path of an object in uniform motion is a straight line.
Answer:
Final temperature of the copper is 59 degrees Celsius
Explanation:
It is given that,
Mass of the sample of copper metal, m = 6.5 g
Initial temperature of the metal, 
Heat generated, Q = 84 J
The specific heat capacity of liquid water is 0.38 J/g-K
Let 
is the final temperature of the copper. It can be calculated using the definition of specific heat of any substance. It is given by :
or
So, the final temperature of the copper is 59 degrees Celsius. Hence, this is the required solution.
