1. QUESTION 1 The number of cycles per unit of time is defined as frequency. True False 2 points QUESTION 2 1. The frequencies of two tuning forks

Hello, please answer 10 questions, if get full points, will add tips.

QUESTION 1 1. The number of cycles per unit of time is deFned as frequency. True ±alse 2 points QUESTION 2 1. The frequencies of two tuning forks are 211.17 and 290.81 Hz respectively. If they are struck and held close together, what is the beat frequency? 2 points QUESTION 3 1. What is the speed of sound in air under normal conditions in m/s? 2 points QUESTION 4 1. How many meters are 57 cm? 2 points QUESTION 5 1. A bottle has 44.5 liters in volume, how many cubic meter is it? 2 points QUESTION 6 1. In part 3 of this lab, you measure the beat frequency between two tuning forks using two di²erent methods. Method 1 gives you a frequency 68.3 Hz; method 2 61 Hz. What is the percent di²erence of the two values? (Percent diference can be a posiTve or zero value. Please reFer to the lab handout For Formula) 2 points QUESTION 7 1. A wave has a period of 0.0001354158 seconds and a wavelength of 288.78 cm. What is the velocity of the wave in m/s?
