Answer:
Distance ran by basketball player = 4.5 m
Explanation:
We have equation of motion, v = u+at
Substituting
6 = 0 + a x 1.5
a = 4m/s²
Now we need to find distance traveled, we have the equation of motion
v² = u² + 2as
Substituting
6² = 0² + 2 x 4 x s
8 s = 36
s = 4.5 m
Distance ran by basketball player = 4.5 m
Answer:
Explanation:
Displacement is minimum distance between initial and final point .
Distance is total length of path covered in a journey .
a )
Tyler covered a longer distance in the journey because total length of path covered by him is longer due to curved path .
b )
Both have same displacement , because minimum distance between initial and final point in both the case is same .
c )
average speed = distance / time
as time is same for both the case ,
average speed ∝ distance
As distance covered by Tyler is more , his average speed is more .
d )
average velocity = displacement / time
As both displacement and time are same in both the case , average velocity in both the case is same .
e )
They start at the same time and place at the bottom of the mountain and finish at the same time , both have tie and nobody won the race , in spite of speed of Tyler being greater .
The answer is visible light. Most of the solar radiation that reaches the Earth is made up of visible and infrared light. Only a small amount of ultraviolet radiation reaches the surface of the earth. Ordinary sunlight or solar radiation is broken into visible light (0.4 nm - 0.8 nm), ultraviolet light ( 0.4 nm) and the infrared radiation (0.8 nm). The visible light makes up almost half of the total radiation reaching the surface of the Earth.
Answer is C. Light is measured by its wavelength (nanometers) or frequency (hertz).
