The basic barometer can be used to measure the height of a building. if the barometric readings at the top and at the bottom of a building are 665 and 695 mmhg, respectively, determine the height of the building. take the densities of air and mercury to be 1.18 kg/m3 and 13,600 kg/m3, respectively. (round the answer to the nearest whole number.)

The height of the building is 346 m.

Explanation:

Using the pressure formula that relate atmosphera pressure and manometric pressure like: we can find delta of height and delta of pressure. So , knowing that 1(mmHg) is equal to 133 Pa we can do the convertion to 4000 Pa, because the units of Pascal is Newton/(metre^2). Then we solve the formula to get the height: so we get: , now we can .

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
