sodium compound of methyl orange is keep 7 persent sodium.what is minimum molecular weight of compound?

what is the simplest formula of that compound in which x-element (atomic mass = 10g/mol) is 50 persent of total mass and y-element (atomic mass 20g/mol) is 50 persent of total mass?

A student is carrying out an experiment with a cobalt-60 source of labelled activity 0.3 MBq. She holds the source in tongs 25 cm long for the duration of the experiment which is 6 minutes. Calculate the maximum dose and the maximum dose equivalent that she could receive. (The relevant exposure rate constant is 0.35 µSv/ MBq h at 1m).

A pair of charged conducting plates produces a uniform field of Eo = 10,859 N/C directed to the right, between the plates. The separation of the plates is L = 37 mm. In Figure, an electron (e = - 1.6 x 10-19 C; m = 9.1 x 10-31 kg) is projected from plate A, directly toward plate B, with an initial velocity of Vo = 2.1×107 m/s. The velocity of the electron (expressed in general form as a whole number) as it strikes plate B is what?

An electron is confined to a one-dimensional region in which its ground-state (n = 1) energy is 2.00 eV. (a) What is the length of the region? (b) How much energy is required to promote the electron to its first excited state?

compute the decrease in the blood pressure of the blood flowing through an artery the radius in which is constricted by a factor of 4. Assume the average flow velocity is the unconstructed region is 25cm/sec. The density of blood is 1.05g/cm^3. Express the pressure in millimeters of mercury.

A water balloon was dropped from a high window and struck its target 1.17 seconds later. If the balloon left the person's hand at -4.5 m/sec, what was its velocity on impact?

Why AM waves transfer less momentum on striking an object
