Explanation:
It is given that,
Speed of the electron in horizontal region, 
Vertical force, 
Vertical acceleration, 
..........(1)
Let t is the time taken by the electron, such that,
...........(2)
Let 
is the vertical distance deflected during this time. It can be calculated using second equation of motion:
u = 0
So, the vertical distance the electron is deflected during the time is 0.426 mm. Hence, this is the required solution.
Answer:
Balanced forces.
Explanation:
The three main forces that stop moving objects are friction, gravity and wind resistance. Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.
Assuming the cart rests on a perfectly smooth and horizontal surface, then we can apply Newton's second law,
F=ma => a=F/m
Acceleration, a = Force/mass = 16 N / 8 kg = 2 m/s^2
More often than not, the pros outweigh the cons when it comes to nuclear energy. It has very low operating costs, produces sufficient energy to meet demand, and has a variety of other economic benefits that can't be ignored
