Ablow-dryer and a vacuum cleaner each operate with a voltage of 120 v. the current rating of the blow-dryer is 10 a, and that of the vacuum cleaner is 4.0 a.
(a) determine the power consumed by the blow-dryer.
w
(b) determine the power consumed by the vacuum (c) determine the ratio of the energy used by the blow-dryer in 11 minutes to the energy used by the vacuum cleaner in one-half hour. ebd / evc =

Part a)

P = 1200 Watt

Part b)

P = 480 W

Part c)

Explanation:

Part a)

Power consumed by blow dryer is given as

here supply voltage is given as

current rating of blow dryer is given as

Part b)

Power consumed by vacuum cleaner is given as

here supply voltage is given as

current rating of vacuum cleaner is given as

Part c)

Energy consumed in a given interval of time is given as

now we have to find the ratio of energy consumed in time interval of 11 minutes

so we have

now we have

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
