You mean like a box sitting on a table.
One force is the force of gravity, pulling downward on the box.
Now, you know that the forces acting on the box must be balanced, because
if they're not, then the box would be accelerating. But it's just sitting there, so
there must be some other force, just exactly the right strength and direction to
exactly cancel the force of gravity on the box, so that the net force on it is zero.
The other force is the force of the table pushing upward on the box. It's called
the "normal force".
The magnetic field lines start at a magnet's north pole and end at the south pole.
A. They begin on north poles and end on south poles.
<u>Explanation:</u>
Magnetic field lines are a visual instrument used to speak to attractive fields. They portray the bearing of the attractive power on a north monopole at some random position. The north post of one magnet draws in the south shaft however repulses the north shaft of another magnet dissimilar to shafts pull in and like shafts repulse.
A metal is a magnet on the off chance that it repulses a known magnet. Be that as it may, the Magnetic field lines don't simply end at the tip of the magnet. They go directly through it so that inside the magnet the attractive field focuses from the south shaft toward the north post.
Answer:
C
Explanation:
Because...
A= Incideant ray
B= Angle of inciderance
<u>C= angle of reflection</u>
D= reflection ray
Since the ball was not moving before it let Aiden's hand, the formula used to calculate the acceleration is
, where a is acceleration, v is velocity and t is the time. We put them in the formula and get
The acceleration is 490 m/s^2
