Answer:
Mandible.
Explanation:
The mandible in the bone that allows you to open and close your mouth, otherwise known ad the jawbone.
Power is the work done per unit time. Therefore,
Therefore,
Answer:
16 ohms
Explanation:
V=
I
⋅
R
where, V is the net potential difference in the circuit, I is the current in the circuit and R is the net resistance of the circuit.
In this case, V
=
240 volts, I
=
15 amperes.
240
=
15
⋅
R
⇒
R
=
240/
15
=
16 ohms
I have no idea I need the answer too
