![]() ![]() Two tuning forks produce 5 beats per second. What is the frequency of A after scraping?ġ0. When the prongs of A are scraped by a file and sounded with B, then 4 beats per second are heard. What is the frequency of the other fork? Ans. On loading the other with a small wax, the number of beats per second becomes 5. Two tuning forks, on sounding together, produce 3 beats per second. What will be the time-interval between two consecutive beats produced by sounding them together? Ans. The frequencies of two sound-sources are 512 and 516 Hz. Determine the possible frequencies of the other fork.ħ. When it is sounded with another tuning fork, 8 beats per second are produced. The period of vibration of a tuning fork is ( 1/288 ) second. ![]() Calculate how long it took Person 1 to complete 9 procedures.6. Most of the procedures took 45 minutes each to create, but two of Person 1's procedures took 2 hours each. (7,3) Person 1 writes internal operating procedures 2 times faster than Person 2. Chemical energy What happened to energy imports from about 1979-1986 Which is the midpoint of AB if A is (-4,-1) and B is (10,5)? A. How many hours will it take Ashley and 4 of her friends to prepare 1575 bags of samples? A ball held above the floor has what type of energy? A. It takes each of her friends 75% longer to prepare a bag. It takes Ashley 2/3 of a minute to prepare one bag. She wants to advertise her products by distributing bags of samples in her neighborhood. ANYONE PLS SERIOUSLY PLS HELP ME What is a responsibility of a family Ashley recently opened a store that uses only natural ingredients. Based on the model, what is the estimated increase, in centimeters, of the length of the fish each month? (2a^2 + ab +2b)+(4a^2-3ab+9) What are the economic, political, religious, and social developments in the early Indus River Valley civilizations? SOMEONE HELP I REALLY CAN'T FAIL THIS PLS I HAVE TO GET IT IN TODAY PLS!ĬAN SOMEONE HELP ME. Physical systems Which form of government has developed in most countries of central and Western Europe What phrase best defines mood in literature A biologists uses the equation l = 2a + 13.1 to estimate the length (l), in centimeters, in terms of the age (a), in months. ![]() NO2(g) or N2O4(g) As a geographer, which essential element of geography would you be studying if you used this map to study locations? A. The same molar amount is used in the comparison. For each pair of substances listed here, choose the one having the larger standard entropy value at 25✬. Divinding a long search key into pieces and combining them through addition or a bit wise boolean operation is called A. a) How far must the lens be from the film in order for the resulting picture to be clearly focused? Answer in units of cm. The photographer is taking pictures of ancient trees in a forest and wants the lens to be focused on a very old tree that is 10.4 m away. Why should we favor programming to interfaces over implementations? A nature photographer is using a camera that has a lens with a focal length of 3.06 cm. (a) What is the speed of the star, and (b) is it approaching or receding from the Earth? (c) If the star’s emitted wavelength is the same as the rest value, what is happening?. The rest wavelength of this line is 656.8 nm. 0.05 T 2T d.0.2 T A spectral line from a star is observed to have a wavelength of 656.5 nm. If in the experiment, the wire carrying a current 2.0 Ahow strong is the magnetic field? 2.0.1 T b. True o False In magnetic force on a current carrying wire" expriment using the data for force (y-axis, in Newton) versus length in meters), someone obtained a linear curve fit countion: y=0.1x+2. 5 3 in Z1o When an automobile rolls on pavement, the instantaneous center of one of its wheels is located on the wheel axle. Find the values for each of the following: a. ![]()
