In the Young double slit experiment, coherent light of wavelength λ from a single source illuminates a system of two slits separated from each other by a small distance a. Each slit causes the light enter...

Multiply both sides by 5: 5x = 3r - 4Add 4 to both sides: 5x + 4 = 3rDivide both sides by 3: (5x + 4)/3 = r

Let radius of cylinder be r. Let height of cylinder be h. We know that the volumes of the hemisphere and cylinder are equal:2(pi)r³/3 = h(pi)r².Multiplying both sides by 3 and dividi...

8 marks can be achieved through two well-developed, equal paragraphs, each earning 4 marks.The first step is a direct answer: at the beginning of each paragraph the student should give a 'first-sentence a...

75g = 0.075kg/ 37.5cm³ = (37.5 divided by 100³) m³ = 3.7510^-5m³/ density = mass divided by volume/ 0.075 divided by 3.7510^-5 = 20...
