Answer:
lack of proper nutrition, caused by not having enough to eat, not eating enough of the right things, or being unable to use the food that one does eat
Well, we usually assume that the resistance of a circuit component
is constant and doesn't change. But the truth is that for anything
that conducts current, its resistance always increases somewhat
when it warms up.
For things like light bulbs, electric toasters, space heaters, electric
stove burners, the heat coils in a blow-dryer ... anything that's
designed to be really hot when it's doing its job ... the resistance
of those things increases significantly when they come up to their
operating temperatures.
Answer:
1.31 m
Explanation:
The relationship between frequency and wavelength of a sound wave is
where
c is the speed of the wave
f is the frequency
is the wavelenfth
In this problem, we have
c = 343.06 m/s
f = 261.63 Hz
So we can solve the formula for the wavelength:
The answer to that is c hope it helps
Answer: 480 kJ
Explanation: Energy = power · time
E = Pt = 4000 W · 120 s = 480 000 J
