How to Trick Your Brain Into Loving Study Sessions (Seriously)

Studying doesn’t have to feel like a slog. The truth is: your brain isn’t built to drag through hours of tedium—it responds best to pattern, reward and rhythm. By shifting how you approach study time, you can turn it from duty into something your brain actually enjoys. ‎Here are five simple, smart ways to do it. Try one today and see how your focus follows. ‎1. Study in Short Bursts, Not Endless Sessions    ‎Forget the idea that you must sit for three hours straight. Cognitive science shows our attention drops significantly after about 25–30 minutes. So use the Pomodoro Technique : study for 25 minutes, take a 5‑minute break; after four rounds, give yourself a longer break (15–20 minutes). That rhythm gives your brain permission to reset—and makes that “next block” easier to start.  ‎2. Turn Learning into a Game ‎The brain loves victory—even tiny ones. Set fun micro‑challenges: finish chapter one in 20 minutes, get 10 questions right in a row, or beat yesterday’s time. E...

How to calculate velocity of sound wave at a given temperature

  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...
