A50.0 n box is at rest on a horizontal surface. the coefficient of static friction between the box and the
surface is 0.50, and the coefficient of kinetic friction is 0.30. a horizontal 20.0 n force is then exerted
on the box. the magnitude of the acceleration of the box is most nearly

Acceleration will be

Explanation:

We have given that a 50 N box is at rest

Coefficient of static friction = 0.5

And coefficient of kinetic friction = 0.3

Force exerted on the box = 20 N

Static friction force =

As the static friction force is greater than the force exerted force so box will not move and so acceleration will be

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
