Answer:
An object appears white when it reflects all wavelengths and black when it absorbs them all. Red, green and blue are the additive primary colors of the color spectrum. Combining balanced amounts of red, green and blue lights also produces pure white.
Explanation:
V=u+at
V= speed 0 m/s
u = initial speed 9.3 m/s
a = acceleration - 4.5 (negative)
0=9.3-4.5t
t=9.3/4.5= ? :) seconds
Answer: SI Unit is meters per second(m/s)
Explanation:
The three units of speed are:
