Answer:unbalanced: have direction,Change an objects motion, causes object to accelerate
Balanced:Do not change an objects motion, Net forces equal sum of all forces on object, and Does not equal 0 N
Explanation: Thats all I know Hoped I helped sum
F = 52000 N
m = 1060 kg
a= F/m = 52000 N/1060 kg = 49.0566 m/s^2
Answer:
(a) 
(b) 
(c) 
Explanation:
(a) The orbital period is the time that the electron spend to travel the orbit of the atom. Thus, it is given by the length of the circular orbit divided by its velocity:

(b) Current means charge over time, So, in this case is charge over period:

(c) Magnetic moment is given by:

Here A is the area of the orbit.

The gravitational force.
In fact, the motion of the projectile is composed by two independent motions:
- on the horizontal direction, it is a uniform motion (with constant speed)
- on the vertical direction, it is a uniformly accelerated motion, where the vertical acceleration g is given by the gravity exerted by the Earth on the projectile.
For this reason, the composition of the two motions results in a parabolic trajectory.
A and b!
hope this helps!
