![]() ![]() 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. ![]() ![]() Thus the frequency is inversely proportional to temperature.6. Note:When we are given questions related to tuning fork, we have to note the temperature in the given system as well, because the pitch of the tuning fork varies with temperature due to a decrease in value of the modulus of elasticity of steel with an increase in the temperature. Thus we can conclude that option B is the correct answer. Hence, we have calculated the velocity of sound in air as $326.4 m/s$. We are also given that their wavelengths produced by each fork differs by 6 cm, that is In the question, we are given two tuning forks of frequencies 320 Hz and 340 Hz that can produce sound waves in air. If v is the velocity of sound in air, $\upsilon $is the frequency and $\lambda $is the wavelength then we can relate the three values as We can find the velocity by relating it with the frequency and the wavelength. The vibration of the tuning fork occurs when it is hit hard with a tool like a rubber hammer and it leads to the production of disturbances in surrounding air molecules. Hint:A tuning fork is a suitable representation to show the production of sound by vibrating objects. ![]()
