A force f is given by f = at + bt² where t
is the time
What is the dimension of a and b.

The net force would equal 13 newtons , forward. the mass will accelerate. balanced forces: when forces are in balance, acceleration is zero. velocity is constant and there is no net or unbalanced force.hope this : )

Biological effects of low exposure to radiation: damage cells.damage dna.are hard to detect.are repaired by the body.biological effects of high exposure to radiation: kill cells, tissues, and organs.produce a variety of cancers.result in acute radiation syndrome.
