The water in the plumbing in a house is at a gauge pressure of 300,000 pa. What force does this cause on the top of the tank ins
liraira [26]

Answer:

60 000 N

Explanation:

1 pa = 1 N/m^2

you have 300 000 of these   = 300 000 N /m^2

    but only an area of .2 m^2

                    300 000 N / m^2  * .2 m^2 = 60 000 N

If a certain gas occupies a volume of 12 l when the applied pressure is 6.0 atm , find the pressure when the gas occupies a volu
dolphi86 [110]
From Boyle's law, the volume of a fixed mass of a gas is inversely proportional to its pressure at constant absolute temperature. 
Therefore; P1V1 =P2V2; where PV is a constant
hence; 12 × 6 = 3× p2
           p2 = 72/3
                = 24 atm
Therefore; the new pressure will be 24 atm

An ammeter with a resistance of 5.0 ohm is connected in series with a 3.0V cell and a lamp rated at 300 mA, 3V. Calculate the cu
Alex

Answer:

I = 0.2 A

Explanation:

Lamp is rated at 300 mA

I_lamp = 0.3 A

Voltage is; V = 3V

Thus; Resistance is given by;

R = V/I

R = 3/0.3

R = 10 ohms

Now, since the ammeter of 5 ohms is connected in series with the lamp. Thus equivalent resistance;

R_eq = 10 + 5

R_eq = 15 ohms

Ammeter current will be;

I = V/R_eq

I = 3/15

I = 0.2 A
