B
Scientific laws are facts that describe observed reoccurring natural events.
When the truck accelerates forward the ball will shift to the back of the bed of the truck because of inertia
F=ma, in this case your force=-883 N and mass = 90 kg. F/m=a therefore acceleration=-883/90=-9.81 m/s/s
The person travels 2.93 (it’s a repeating decimal so 2.933333 but round it to whatever it says round it to) feet per second
Answer:
It reveals that light is a wave
Explanation:
Diffraction is the property of a wave in which there is a bending of the wave about the corners of an obstacle or aperture into the geometrical shadow of the obstacle or aperture.
This simply implies that a wave bends or spreads out when it passes through openings. Since the light diffracts through small slits and diffraction has been shown to occur in water waves and sound waves, this property of diffraction can only be characteristic of a wave and thus, this evidence reveals that light is a wave.
