Answer:
Average velocity = 18 m/s
Explanation:
Given the following data;
Initial velocity = 10m/s
Acceleration = 2m/s²
Time = 4 seconds
To find the average velocity, we would use the first equation of motion;
Where;
V is the final velocity.
U is the initial velocity.
a is the acceleration.
t is the time measured in seconds.
Substituting into the equation, we have;
V = u + at
V = 10 + 2*4
V = 10 + 8
V = 18 m/s
Refraction and reflection both shows the wave property of light and the difference between them is that during reflection the medium of light will not change while in refraction the light will change its medium
so in reflection of light we use that angle of incidence = angle of reflections with respect to normal
While in refraction we use Snell's law
Diffraction of light is the phenomenon of light in which light will bend at the corners and enter into the region of dark
While absorption is the phenomenon of energy absorption when light incident on any medium or surface
Answer:
Passive range of motion can be defined as what is achieved when an outside force, such as a therapist, causes movement of a joint. It is usually the maximum range of motion. Active range of motion is what can be achieved when opposing muscles contract and relax, resulting in joint movement
the strength and vitality required for sustained physical or mental activity.
