Aclosed container is filled with oxygen. the pressure in the container is 435 kpa . what is the pressure in millimeters of mercury?

First of all, let's convert the pressure in Pascal:

Keeping in mind that , we can convert it into atmospheres:

We know that 1 atm corresponds to 760 millimeters of mercury, so we have:

From which we find the pressure in millimeters of mercury:

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
