The earth rotates (spins) at the same time as it orbits in a circular motion around the sun. fun fact : it takes 365 days to complete 1 orbit for 3 years and then 366 days for a leap year! you don't have to put that last part but maybe for some extra points you can!
<span>Magnetic separation takes advantage of differences in the magnetic properties of minerals. Minerals fall into one of three magnetic properties: ferromagnetic, paramagetic and diamagnetic</span>
(30, 5)
(10, 1)
change of y / change of x
= (30 - 10) / (5 - 1)
= 20 /4
= 5
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
Their final velocity is 0.48 m/s.
We can use conservation of momentum to calculate the magnitude of the final velocity.
Momentum before collision is equal to the momentum after collision
m1v1+m2v2=(m1+m2)v
here, v is final velocity , assuming right side velocity as positive, and left side velocity as negative.
14*(-1.1)+18*(0)=(14+18)v
v=-0.48 m/s
Here, negative sign indicates that they both will move in left direction.
