Answer: 39.948
Explanation:
How many grams Argon in 1 mol? The answer is 39.948. We assume you are converting between grams Argon and mole. You can view more details on each measurement unit: molecular weight of Argon or mol The molecular formula for Argon is Ar.
Let the person at the Left be A and Person at the right be B
then the force by person A will be
Pulling force + Frictional Force = the force by the person
which is,
20N+11N=29N
then the force by person B will be,
25N+5N=30N
1) the net force will be 30N-29N=1N
2) the force are unbalanced as the net force acting on the object is not zero.
3) the rope will move towards the right as there is a net force of 1N towards the right.
