<span>Matter of all types have gravity, which causes it to attract to each other. The most efficient way for all this matter to congregate is the sphere. As they consolidate, they form the shape. As they compress, temperatures in the center of the mass start to go up and if it hits the proper point, it can ignite and become a star.</span>
Answer:
Radius,
Explanation:
It is given that,
Magnetic field, B = 0.275 T
Kinetic energy of the electron,
Kinetic energy is given by :
v = 1037749.04 m/s
The centripetal force is balanced by the magnetic force as :
So, the radius of the circular path is . Hence, this is the required solution.
Distance = (speed) x (time)
Distance = (20 m/s) x (500 s)
Distance = (20 x 500) (m·s / s)
Distance = 10,000 m
Answer:
1) Lightning, you see the lightning first and then hear the thunder.
2)When a person far away from you hits a ball with a bat, you can see them striking the ball first and then you will hear the sound of ball striking against the bat.
