are you a dmbss? the bulb and wire must be connected to both end
V^2-u^2=2as
v=final velocity=unkown
u=initial velocity=0 m/s, because freely falling
a=acceleration due to gravity=9.8 m/s^2
s=distance (here height) traveled=4.5m
therefore the final velocity,
v^2=2*9.8*4.5
v=<span>9.39m/s</span>
Answer:
c = 3.00E108 m/s = 3.00E5 km/s
t = S / v = 3.84E5 / 3.00E5 = 1.28 sec
Answer:
Absorbed and reflected
Explanation:
B is reflected because you can’t see the red arrow which represents a light that bounces off of it and a aired up sword because you can see it win through the object shown in the picture
