Studying abroad can be a life-changing experience for everyone who has the dream of doing so because it provides opportunities to explore new cultures, learn new skills, and boost your academic profile. However, the significant barrier which is associated with international study is the cost. This is where scholarships can play a very important role, it make studying abroad possible for students who have the academic dreams to study abroad. A comprehensive guide on how to access scholarships for studying abroad is listed below: Step One: Research and Identify Scholarships The first thing is to research scholarships that match your academic profile,your strength or interests, and your academic goals. You can make use of online databases, university websites where you hope to study, and government resources to find relevant opportunities. Some governments, universities, organizations, and private foundations (like NGOs) offer scholarships, you can look...
Question 1 A source of sound wave of frequency 660Hz emits waves of wavelength 0.12m in air at 40 o C. What is the velocity of sound wave in air at this temperature? What would be the wavelength of sound wave from the source in air at 70 o C? Answer Frequency = f = 660Hz Wavelength= λ = 0.12m Temperature = 40+273 = 313K Velocity of sound wave at 40 0 C V = fλ = 660 x0.12 =79.2m/s Wavelength of wave at 70 0 C Note: to find the wavelength, we must find the velocity of the sound wave at 70 0 C. Velocity of sound wave is directly proportional to the square root of its temperature in kelvin. V 1 /V 2 = √T 1 /√T 2 V 1 = 79.2m/s T 1 = 313K T 2 = 70 + 273 = 343K 79.2/V 2 = √313/√343 79.2 2 /(V 2 ) 2 = 313/343 313(V 2 ) 2 = 79.2 2 x 343= 2151515.52 (V 2 ) 2 = 2151515.52/313 (V 2 ) 2 = 6873.9 V 2 = √6873.9 = 82.9m/s Since V=fλ then 82.9 = 660 x λ .λ = 82.9/660 =0.13m Question II A sound wave of v...
