Answer:
Explanation:
1. The net force acting on an object is the combination of all of the individual forces acting on it.
2. If two forces act on an object in opposite directions, the net force is the difference between the two forces.
3. If two forces act on an object in the same direction, the net force is the sum of the two forces.
X-axis=time
y-axis=distance (position)
slope=y-axis / x-axis=distance / time=velocity.
answer: d) slope
Answer:
nπ + π/2 for any integer n
Explanation:
Since destructive interference occurs every odd multiple of half wavelength, that is π/2, 3π/2, 5π/2 where the interference is half wavelength and in general, (n + 1/2)π where n is an integer. So, nπ + π/2 for any integer n
Density is mass per unit volume. In this case, the unit is g/ml
Mass=453g ρ=453g/224ml
Volume=224ml ρ=2.022g/ml(rounded to nearest hundredth)
Density=?
ρ=mass/volume
Therefore the density of the substance is 2.022g/ml
