Answer:Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P." Neutrons have no electrical charge.
Answer:
v = 26.52 m/s
Explanation:
Here we know that as she passes the flag she will gain some speed
so here we can say that
Work done by all forces = change in kinetic energy of the system
so we will have

here we know that



h = 39.78 m
d = 27.81 m
so we have



The number of ocean waves that pass a buoy in one second is the frequency of the <span>wave. The crest of a transverse wave is its highest point. </span>
If it is average speed per hour, then you just have to divide 3.5 into 60
60/3.5 = 17.143 so around 17km/h
