Answer:
C: Light travels from the Sun to the grass and is then reflected to your eyes.
Explanation:
Our eyes don't produce light but detect light (so answer A is not correct)
The grass doesn't produce light unless it is burning (discard answer B)
Answer C is the correct one.
The light we detect from the grass is not light bounced off the sky, it comes directly from the grass to your eyes (you are not looking at the sky when you see the grass) Discard answer D
Answer:
t=0.47s
Explanation:
the ball has uniformly accelerated movement due to gravity
Vo=initial speed=4.6m/s
g=gravity=-9.8m/s^2
Vf=final speed=0, the player must wait for the ball to stop. so the final speed will be 0
we can use the following ecuation
T=(Vf-Vo)/g
T=(0-4.6)/-9.8m/s^2
T=0.47s
Answer:
257.32
Explanation:
I jus worked it out on paper. Brainliest please?
Initial velocity (u) = 2 m/s
Acceleration (a) = 10 m/s^2
Time taken (t) = 4 s
Let the final velocity be v.
By using the equation,
v = u + at, we get
or, v = 2 + 10 × 4
or, v = 2 + 40
or, v = 42
The final velocity is 42 m/s.
