Okay so yeah u have to minus then subtract then decide it it’s a method i was taught to do
If you take 50 meters and divide by 23.1 seconds, you will get 2.16 meters per second.
So his average speed is 2.16 m/s.
Organisms, organs, tissues, cell ....
a more specific answer would be:
organism, organ system, organ, tissue, cell, atom
Emf e = 11
r 1 = 3.0
r 2 = 3.0
r 3 = ?
The two in parallel are equivalent to 3 • 3/6 = 1.5 Ω
To have 2.4 volts across them, the current is I = 2.4/1.5 = 1.6 amps. and the unknown R = (11–2.4) / 1.6 = 5.375 Ω or 5.4 Ω
Land animals could eat water animals
For example, a bear could eat salmon from the river and that could be connected to organisms from water to land
