Radioactivity was discovered in about 1895 or 1896.
Explanation:
both are areas of land that drain to particular water bodies such as lakes
Answer:
he electron moves in the direction of a greater electric potential
Explanation:
Electric potential and electric field are related
V = -∫ E .ds
t
he electric force is related to the electric field
F = q E
F = q (-dV / ds)
since the electron has charge a = 1.6 1019 C
F = e dv / ds
therefore the electron moves in the direction of a greater electric potential
Gravity is the cause of formation waves.
The rule to get the average speed is as follows:
average speed = average distance / average time
We are given that:
distance = 250 m
time = 110 sec
Substitute with the givens in the above equation to get the average speed as follows:
average speed = 250/110 = 25/11 meters/sec
