The final velocity of the ball that is dropped from a height of 200m is v = 44.73 m/s .
<h3>What is velocity with example?</h3>
The rate at which an object is travelling in one direction is referred to as its velocity. an automobile traveling north on a highway, or a rocket taking off. Its velocity vector's absolute value always is equal to the motion's speed because it is a scalar.
<h3>Briefing:</h3>
Given the initial velocity of the ball (u) = 0
Distance travelled by the ball (s) = 200m
Acceleration (a) = 10 m/s²
As we know:
v² = u² + 2as
Putting values:
v² = 0+2 × (10 m/s²) × (200 m)
v = 44.73 m/s.

Answer:
A Pulsar
Explanation:
Such white dwarf is a Pulsar (from pulsating star). Three main features we find in this kind of celestial body
1. Incredibly high density, in a pulsar there is not what we can define as free interspace. Everything is mass
2.- Huge rotational speed (more than hundreds of kilometer) spinning at more than hundreds of kilometer per second
3.-Intense magnetic field
Combinations of thse features make pulsar emits important amount of energies with pricese periods of time. And if on earth we look a jet of electromagnetic radiation with a precise rigurosity (at pricese period of time) is because we are looking a pulsar spinning and each time the radiation appears is a turn of the pulsar
Answer:
static electricity is a flowing charges
Usually, you have to take two years of physical sciences with lab. It doesn't have to be physics, it can be chemistry or biology.
