Using v=u+at, Where v is final velocity(m/s), u is initial velocity(m/s), a is acceleration(m/s^2) and t is time(s).
v = 0 + 3.2*6
v=19.2 m/s.
A, the type of disinfectant used, is a variable. The other three are controls.
Answer:
D.The potential energy per unit charge
Explanation:
Electric potential of a charged particle:
It is scalar quantity because it has magnitude but it does not have direction.
It is the amount of work done required to move a unit positive charge from reference point to specific point in the electric field without producing any acceleration.
Mathematical representation:

Where W= Work done
= Unit positive charge
Other formula to calculate electric field:

Where K=
It can be defined as potential energy per unit charge.
Hence, option D is true.
Answer:
it depends who throwing the softball and the velocity depends on the person who chucking the ball at 90mph and then there's 100mph
Explanation:
Because the heat in your breath can help rise the humidity also causing the humidity only to raise it little by little, but it also helps some moist climates.
