Given :
Mass of block , M = 20 kg .
Force applied , F = 80 N .
Acceleration of block , .
To Find :
The coefficient is Kinetic force friction between the block and the table .
Solution :
We know , Force equation on block is given by :
Therefore , coefficient is Kinetic force friction between the block and the table is 0.15 .
Hence , this is the required solution .
Nuclear<span> fusion occurs in the core area or center of the Sun. Here, temperatures are around 15,000,000°C. Gravity pulls all of the mass of the Sun inwards, creating pressure so intense that </span>nuclear<span> reactions take place. The nuclei of hydrogen atoms smash together and fuse to form larger atoms such as helium nuclei. Hope this helps!! :) </span>

Answer:
We use the relationship F = m x a, adapted for Weight: W = m x g
Weight is the force, m is the mass and g is the acceleration of gravity. Take an example: you are 100 kg made up of 70 kg of body mass and 30 kg of space suit. Your weight on the Moon would be 100 kg x 1.62 m/s^2 = 162 Newtons (weight force).
On Earth that would be a Weight of 100 kg x 9.81 m/s^2 = 981 Newtons.
