A1500-w heater is designed to be plugged into a 120-v outlet.
what current will flow through the heating coil when the heater is plugged in? i = a
what is r , the resistance of the heater?
how long does it take to raise the temperature of the air in a good-sized living room 3.0m x 5.0m x 8m by 10 degrees c? note that the specific heat of air is 1006 j/(kg x degrees c) and the density of air is 1.20 kg/m^3.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

does anyone know or what?

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

not too sure thinking all accelerations are pointed down
