F=ma which is newtons second law. so we have here a=g in this situation and g=gravity and that equals 9.80m/s^2 on earth surface. So we have F=5.7kg*9.80m/s^2=55.9N or Newtons. Thank You! Please rate!
Answer: Creative thinking
Explanation:
It should be noted that, Creative Thinking is the method by which a problem is solved with the help of thinking skills.
The thought that is present in mind is tries in the practical life so that the problem can be solved.
Going by the question asked, Mandleev was trying to arrange elements in a logical way. He thought of arranging the elements based on the atomic weight.
This gives a good oexample of creative thinking in which the thinking is applied and a logical result is product of the thinking.
Answer:
I believe the answer is B) Two wavelengths
Answer:
D) ¼ as large
Explanation:
The magnitude of the electric force between two charges is
where
k is the Coulomb's constant
q1 and q2 are the magnitudes of the two charges
r is the separation between them
From the formula we see that the magnitude of the force is inversely proportional to the square of the distance.
In this problem, the distance is doubled:
So the new force will be
So the force will decrease to 1/4 of its original value.
Aluminium is less dense which is lighter and the cast iron has more dense that's why it's heavier :)
