It channels erode wider fed by many tributaries and has more discharge and is less steep
the answer is D) The air in the aquarium is saturated
none of the other answers were realistic AND I took this before so I know the right answer.
Explanation:
It is given that,
Mass of an electron,
Initial speed of the electron,
Final speed of the electron,
Distance, d = 5 cm = 0.05 m
(a) The acceleration of the electron is calculated using the third equation of motion as :
Force exerted on the electron is given by :
(b) Let W is the weight of the electron. It can be calculated as :
Comparison,
Hence, this is the required solution.
Explanation:
The Coulomb's law states that the magnitude of each of the electric forces between two point-at-rest charges is directly proportional to the product of the magnitude of both charges and inversely proportional to the square of the distance that separates them:
In this case we have an electron (-e) and a proton (e), so:
In this case, the electric force is negative, therefore, the force is repulsive and its magnitude is:
