Answer:
The answer is:-
Explanation:
An electron emitted from an atom by enteraction with an photon, especially an eclectron emitted from a solid surface by the action of light.
Answer:
b) 0.5 m/s
Explanation:
let V be the averare speed of the object.
the average speed is given by:
V = total distance / total time
= (20+20)/(30+50)
= 0.5 m/s
Therefore, the average speed of the object is 0.5 m/s.
The amount of energy before and after any energy transformations remain the same because energy cannot be created or destroyed. From the law conservation of energy; any time energy is transferred between two objects, or converted from one form into another, no energy is created and none is destroyed. The total amount of energy involved in the process remains the same.
Initial velocity = 5mph
final velocity = 7mph
Answer:
The correct answer is B. You would not have to travel far to see another total eclipse .
Explanation:
it is said that the way to predict or know beforehand if there is a lunar or solar eclipse is just to know the what is called the saros which are periods of exactly 223 synodic months and the eclipses are repeated or occurred in the same location every 3 Saros cycles.
