Gametes are the cells used during sexual reproduction to produce a new individual organism.
Explanation:
The male gamete or sperm, is a smaller, mobile cell that meets up with the much larger and less mobile female gamete, egg or ova.
If the current takes him downstream we must find the resultant vector of the velocities:

Then if the river is 3000 m-wide the swimmer will have to pass:
1.3520747 · 300 = 4056.14 m t = 4056.14 m : 1 m/s
a ) It takes
4056.15 seconds ( 1 hour 7 minutes and 36 seconds ) to cross the river.
b ) 0.91 · 3000 =
2730 mHe will be 2730 m downstream.
Sewage. If thats not it, then I need to see your choices. :)
Answer:
The second one is correct.
Explanation:
=
Answer:

Explanation:
By conservation of the linear momentum:
m1*V1 = (m1+m2)*V2
Solving for V2:

The kinetic energies are:



Simplifying:

The ratio will be:
