Answer:
if they move to their respective sides at the same time then they are moving at exactly the same velocity
so that means they have the same speed and velocity

EXPLANATION:
First copy the 15 and u will × now in the no. of (9.8 ×1.5) the equal is 15 m/s -14.7m/s so we - the now the 15-14.7 and the ANSWER IS 0.3m/s.

Answer:
infrared waves
radio waves
ultraviolet waves
Explanation:
Radio waves are used for communication such as television and radio.
Infrared light is used by electrical heaters, cookers for cooking food, and by infrared cameras which detect people in the dark.
Ultraviolet radiation can kill bacteria that are present in water - this sterilises the water and makes it safe to drink.
Answer:
640 m.
Explanation:
The following data were obtained from the question:
Acceleration (a) = –20 m/s/s
Time (t) = 8 s
Final velocity (v) = 0 m/s
Distance (s) =.?
Next, we shall determine the initial velocity (u) of the car. This can be obtained as follow:
Acceleration (a) = –20 m/s/s
Time (t) = 8 s
Final velocity (v) = 0 m/s
Initial velocity (u)
a = (v – u) / t
–20 = (0 – u) / 8
–20 = – u / 8
Cross multiply
–20 × 8 = – u
– 160 = – u
Divide both side by – 1
u = – 160 / – 1
u = 160 m/s
Finally, we shall determine the distance travelled by the car before stopping as follow:
Time (t) = 8 s
Final velocity (v) = 0 m/s
Initial velocity (u) = 160 m/s
Distance (s) =.?
s = (v + u)t /2
s = (0 + 160) × 8 /2
s = (160 × 8) /2
s = 1280 / 2
s = 640 m
Therefore, the car travelled 640 m before stopping.
Answer:
B is the answer because it's the closest to the sun, so it has a smaller path.
