AnnZ [28]3 years ago
4 0

Answer:

Mechanical waves require a medium in order to transport their energy from one location to another.

Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist.

If the velocity of a pitched ball has a magnitude of 47.0 m/s and the batted ball's velocity is 55.0 m/s in the opposite directi
Naddik [55]

Answer:

14.79 kgm/s

Explanation:

Data provided in the question

Let us assume the mass of baseball =  m = 0.145 kg

The Initial velocity of pitched ball = v_i = 47 m/s

Final velocity of batted ball in the opposite direction = v_f= -55m/s

Based on the above information, the change in momentum is

\Delta P = m(v_f -v_i)

=  0.145 kg(-55m/s - 47m/s)    

= 14.79 kgm/s

Hence, the magnitude of the change in momentum of the ball is 14.79 kg m/s

What is the three laws of electrostatics?
dangina [55]

The force exerted between 2 point charges is directly proportional to the product of their strengths, is inversely proportional to the square of the distance between them and is inversely proportional to the absolute permittivity of the surrounding mediums.

I hope that helps somewhat, I'm only kind of sure that could be correct
