Answer:
New gravitational force, F' = 216 units
Explanation:
Given that,
Gravitational force between object 1 and 2, F = 72 N
The gravitational force between two objects is given by :
............(1)
If the mass of object 1, 
If the distance between objects is halved, 
Let new gravitational force is F'. It is changed to :
F' = 216 units
So, the new gravitational force will be 216 units.
Answer:
The answer is %pearlite = 0.06%
Explanation:
according to the exercise we have that the percentage is 1.88% C, therefore, the percentage of perlite is equal to:
%pearlite = (B*C)/(A*C) = (2-1.88)/(2-0) = 0.06%
The percentage of cementite is equal to:
%cementite = (1.88-0)/(2-0) = 0.94%
Answer:
Density is independent of the
amount of the sample. (D)
Explanation:
Because density is an intrinsic property of matter.
hope it helps!
Answer:yes
Explanation:
Work is done on an object when an applied force causes the object to move in the same direction as the force
