Answer:
yes
Explanation:
when we throw a ball upwards, it will eventually come back to us because of force.
Answer:7.93 m/s
Explanation:
Given
mass of ball
Mass of hanging ball
Length of string
Maximum angle turned
is the initial velocity of ball 1 and 0 is the initial velocity of ball 2
For Perfectly elastic final velocity of ball 1 and 2 is given by
where and are the velocity of 1 and 2 before collision
thus
By energy conservation on second ball we get
Kinetic energy=Potential Energy
thus
The best and most correct answer among the choices provided by your question is the second choice or letter b.
Ex is negative from x = -2 to x = 0, and positive from x = 0 to x = 2 <span>correctly describes the orientation of the x-component of the electric field along the x-axis.</span>

Answer:
True
Explanation:
A convex mirror is a mirror whose outer bulging surface is the reflecting surface.
A convex mirror is used to see the distant objects and the image formed by the convex mirror is always erect and small. So, it is used as the rear view mirror.
It always forms a virtual, erect and diminished image of a real object.
It never forms a real image of a real object.
