Force is a vector quantity and denotes any interaction that change the motion of an object in a certain direction. When influence by force an object can change its velocity or
The two things that are a included when describing force are: magnitude and direction. To fully describe the force acting upon an object, you must describe both the magnitude (size or numerical value) and the direction.
Answer:
We know ForceF=mass×acceleration----------(1)
And given ForceF=

Not pushing yourself hard enough is the answer since your heart rate doesn't even hit your lower minimum.
Pushing yourself to the limit is at your max heart rate.
Just at the right spot is at your max heart rate.
Pushing yourself too hard is above your max heart rate.
Answer: The correct option is B.
Chromosomes contain genes that tell the body how to grow and work.
Explanation:
This is because chromosomes contain alot of human genes which are found in the nucleus and every humans have 23 pairs of chromosomes. The sets of genes determines some of the body features, characteristics or traits. The genes in the body form the genotype and the genotype is expressed physically which is now the phenotype i.e traits expressed physically in the body which is an indication of body appearance.
