1 is b because a runs 20 and b rus 102 is c
Answer:
Explanation:
The acceleration of an object is given by
where
v is the final velocity
u is the initial velocity
t is the time interval it takes for the velocity to change from u to v
For the car in this problem,
u = 21.0 m/s
v = 46.0 m/s
t = 2.5 s
Substituting, we find the acceleration
Answer:
0.6275 metres
Explanation:
v = fl
125.5 = 200 * wavelength
125.5 / 200 = wavelength = 0.6275m
Im really sorry. pls dont report this comment. i need points. I have a question but I am bad at english and I cant answer peoples
Picture 1 and 2 or am I wrong and it's not that obvious.
