A blow-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 o

Katyanochek1 [597]

Answer:

Part a)

P = 1200 Watt

Part b)

P = 480 W

Part c)

$\frac{E_{bd}}{E_{vc}} = 5 : 2$

Explanation:

Part a)

Power consumed by blow dryer is given as

$P = iV$

here supply voltage is given as

$V = 120 volts$

current rating of blow dryer is given as

$i = 10 A$

$P = (120 V)(10 A)$

$P = 1200 W$

Part b)

Power consumed by vacuum cleaner is given as

$P = iV$

here supply voltage is given as

$V = 120 volts$

current rating of vacuum cleaner is given as

$i = 4 A$

$P = (120 V)(4 A)$

$P = 480 W$

Part c)

Energy consumed in a given interval of time is given as

$Energy = power \times time$

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

so we have

$\frac{E_{bd}}{E_{vc}} = \frac{P_{bd} t}{P_{vc} t}$

now we have

$\frac{E_{bd}}{E_{vc}} = \frac{1200 W\times 11 min}{480 W \times 11 min}$

$\frac{E_{bd}}{E_{vc}} = 5 : 2$

Hydraulic systems utilize Pascal's principle by transmitting pressure from one cylinder (called the primary) to another (called

Paul [167]

Answer:

F1= 122.93 N

Explanation:

Pascal´s Principle

Pascal´s Principle can be applied in the hydraulic press:

If we apply a small force (F1) on a small area piston A1, then, a pressure (P) is generated that is transmitted equally to all the particles of the liquid until it reaches a larger area piston and therefore a force (F2) can be exerted that is proportional to the area (A2) of the piston:

P=F/A

P1=P2

$\frac{F_{1} }{A_{1}} = \frac{F_{2} }{A_{2}}$ Formula (1)
