The battery doesn't 'use' power. The battery <em>produces</em> the power that all the other electrical devices use.
If the starter motor is using 2,520 watts, then the battery is producing energy at the rate of 2,520 watts. That means <em>2,520 Joules</em> of energy every second.
Thanks for giving us the formula.
E = P x t
Energy = Power x Time
Energy = (2,520 watts) x (1 second)
Energy = 2,520 Joules
Answer:
cultural
Explanation:
Cultural anthropology studies the characteristics of the behavior learned in human societies, that is, science of human culture. In general, it is the science that studies the origin, development, structure, characteristics and variations of human culture in both past and present societies. Ethnography, ethnology, archeology, linguistics and physical anthropology are the disciplines on which cultural anthropology is founded.
Acceleration = (change in speed) / (time for the change.
change in speed = (ending speed) - (starting speed) = 9 m/s.
Acceleration = (9 m/s) / (period of 1) .
We don't know the units of the 'period of 1'.
If it means '1 second', then the acceleration is 9 m/s² .
The answer is A. Hope this helps I tried my best!
Good morning.
We calculate the acceleration with the <em>Torricelli equation</em>:

We see that:

Now:

Now we can calculate the
resultant force that makes that acceleration of
0.3 m/s² with the 2nd Law of Newton:

We have a force of
26 N → and a friction force
F ←. Adding those vectors, he have a force
6 N →. Therefore:
26 - F = 6
F = 20 NWe have a friction force of 20 N. We calculate the kinect coefficient with the formula:

Since we are in a horizontal plane, we hava that
N = P = mg = 200 NTherefore:
