Answer:
v = 1.36 cm / y
Explanation:
For this exercise we must assume that the displacement of the plates is constant over time, so we will use the kinematic relationships for the uniform movement
v = d / t
We reduce the quantities to the SI system
d = 320 km (1000 m / 1km) (100 cm / 1 m)
d = 3.2 107 cm
let's calculate
v = 32.107 / 23.5 106
v = 1.36 cm / y
Answer:
f=1/t is the equation of frqency
Im pretty sure its Number 3. Sry if im wrong
Answer:
is called square of Coefficient of Restitution
Explanation:
As we know that the coefficient of restitution is the ratio of the body after collision to the ratio of the body before collision.
<u>Mathematically:</u>
where:
relative velocity after collision
relative velocity before collision
also, in terms of Kinetic energy:
where:
relative kinetic energy after collision
relative kinetic energy before collision
- e=0 for perfectly elastic collision
- 0<e<1 for real world inelastic collision
- e>1 for the collision in which energy is released
- e<1 for the objects passing through one another without fully engaging.
