A football is kicked with a velocity of 31 m/s at an angle of 41º. What is the ball's acceleration in the vertical direction as it flies through the air? A. -9.8 m/s^2
B. 23.4 m/s^2
C. O m/s^2
D. -20.3 m/s^2

Molybdeum(mo)orruthenium (ru)actually, elements with similar chemical properties as technetium would bemn, re, and bh. this is because elements in the same group/family (column) have similar chemical properties. elements in the same period (row) have the same number of energy levels (or shells).

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.

The independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.hope this .
