1. Applying more force and energy, speeding up
2. Releasing potential and kinetic energy by going down a slope, speeding up
3. Applying less force to slow down and let friction overcome the bicyclist
The magnitude of your displacement can be less than your distance traveled And The magnitude of your displacement can be equal to your distance traveled.
Magnitude in physics is simply described as "distance or quantity." It shows the size or direction that an object moves in either an absolute or relative sense. A force's magnitude is defined as the total amount of forces operating on an item. The strength of the force grows if every force is exerting itself in the same direction. The magnitude of the force diminishes when forces are applied to an object from various angles. Meters per second squared is the unit used to measure acceleration. The units must account for both variables since acceleration deals with both velocity and time. The object's current speed is represented by the magnitude of the velocity vector. The velocity vector is pointed in the same general direction as the object's motion. Multiply the constant acceleration rate by the time difference to determine the magnitude of the velocity at any given moment, and then add that value to the beginning velocity.

Explanation:
(a) Net force acting on the block is as follows.
or, ma = -mg Sin (\theta)[/tex]
a =
=
= -3.35
According to the kinematic equation of motion,
Distance traveled by the block before stopping is as follows.
s =
=
= 21.5 m
According to the kinematic equation of motion,
v =
0 =
= 7.16 sec
Therefore, before coming to rest the surface of the plane will slide the box till 7.16 sec.
(b) When the block is moving down the inline then net force acting on the block is as follows.
ma =
a =
=
= 3.35
Kinematics equation of the motion is as follows.
s =
21.5 m =
=
= 3.58 sec
Hence, total time taken by the block to return to its starting position is as follows.
t =
= 7.16 sec + 3.58 sec
= 10.7 sec
Thus, we can conclude that 10.7 sec time it take to return to its starting position.
I think the answer is <span>AM radio </span><span>waves. Im not sure but if its right can you mark my brainliest?
</span>
I believe its E.
Traveling through metal, electrons can not go the speed of light
