Mechanical and chemical. Mechanical breaks down food into smaller pieces. Chemical breaks it down into simpler nutrients that can then be used by cells. Hope this helps!
Multiply the power (1,800 watts) by time (1,200 seconds) to get 2,160,000 joules (or 2.16 MJ)
Take a right triangle and apply pythagorean theorem where the displacement is the hypotenuse:
We get 36.25m
Answer:
1/2
Explanation:
The energy stored in a capacitor is given by:

where
C is the capacitance
V is the potential difference
For capacitor 1, we have

Capacitor 2 has
(half the capacitance of capacitor 1)
(twice the potential difference of capacitor 1)
So the energy of capacitor 2 is

So, the ratio between the two energies is

Answer:
55 mA
Explanation:
Ohm's law states:
V = IR
where V is voltage, I is current, and R is resistance.
220 V = I (4000 Ω)
I = 0.055 A
I = 55 mA
