Which of the following are true for an object in projectile motion?

Physics
1 answer:
Novosadov [1.4K]2 years ago
4 0
The correct options are: B, C and D.

In fact:
- B is true, because the motion of the projectile can be decomposed in two independent motions on the x and y axis. On the x-axis, there is no acceleration; while on the y-axis, the projectile is accelerating towards the ground with g=9.81 m/s^2 (acceleration of gravity)
- C is true, because the two motions on the horizontal and vertical direction are independent. In particular, the horizontal motion is a uniform motion (constant velocity), while the vertical motion is a uniformly accelerated motion (because of the gravitational acceleration g acting on the projectile)
- D is true, in fact (if we neglect air resistance) gravity is the only force acting on the projectile.

Why does sugar dissolves easily in water but sand doesn’t
GarryVolchara [31]

Table sugar dissolves in water because when a sucrose molecule breaks from the sugar crystal, it is immediately surrounded by water molecules. The sucrose has hydroxyl groups that have a slight negative charge. ... Sand can't dissolve in waterbecause the 'spaces' in between the water particles. :)

Which occurs when two or more waves combine to produce a wave with a larger displacement?
Dimas [21]

When two or more waves combine to produce a new wave, that's 'interference'.

-- If the new wave has larger displacements (amplitude), then it's <em>CON</em>structive interference.

-- If the new wave has smaller displacements (amplitude), then it's DEstructive interference.
