- You want to throw a ball a distance of 2l over a wall of height h as is shown in the figure below. Derive an expression for the required angle θ in terms of h and l. Use 'asin' for inverse sin, 'acos' for inverse cos and 'atan' for inverse tan.This answer includes t which is not a variable provided, please answer in terms of the specified variables.The period T of a simple pendulum is the amount of time required for it to undergo one complete oscillation. If the length of the pendulum is L� and the acceleration of gravity is gg, then T� is given by T=2πLpgq Find the powers p� and q� required for dimensional consistency. Enter your answers numerically separated by a comma.
- Part B Problems: Measurement and Uncertainty; Significant Figures; Units, Standards, and the SI System; Converting Units 3. In the Bible, Noah is instructed to build an ark 300 cubits long, 50.0 cubits wide, and 30.0 cubits high. Historical records indicate a cubit is equal to half a yard. (a) What would be the diımensions of the ark in meters? (b) What would be the ark's volume in cubic meter? To approximate, assume that the ark is to be rectangular.One mole of Gold (Au) atom has a mass of 197 g. We know that the density of gold is 19.30 g/cm3 in room temperature. Using those numbers, answer the following questions: a) What is the mass of a single gold atom in kg? b) Assume that gold atoms sit in a perfect cubic crystal structure. Estimate the distance between two gold atoms in meters. c) If we have a gold cube of 6 cm on each side, how many atoms can we fit along the edge of each side of the cube? d) What would be the mass, in kilograms, of the gold cube we discussed in part (c) (measuring 6 cm on each side)?The radius of a circle is measured to be (11.7 ± 0.7) m. Calculate each of the following and give the uncertainty in each value. (a) the area of the circle 430 m² ± 1.54 X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m²

Thank you!!Physical units in mechanics are usually some combination of the dimensions time T, mass M, and length L. Consider the physical quantities m, r, u, a, and t with dimensions [m] = M, [r] = L, [u] = LT-, [a] = LT-2, and [1] = T. Enter the dimensional expression of the quantity on the right-hand side of each equation. Your answers may contain only M, L, T, and exponents. Assume that each of the following equations is dimensionally consistent. Lo = mur [Lo] = W = mar [W] = T
- Write down an expression for the angle in the previous problem if 0 is small (sin 0<<1). Please use appropriate algebraic symbols for multiplication (* for a × b), division (/ for a/b), exponents (a^b for a³), square root (sqrt(a*b/c) for √a × b/c) etc. Please use the "Display response" button to check you entered the answer you expect. 0=For example, dimensional analysis could be used to determine the number of nickels in 3432.35 dollars. 34 dellar • To begin, write down the starting value, 3432.35 dollars. This can also be written as a fraction: Next, convert dollars to cents. This conversion involves a simple conversion factor: delar Note that the "dollar" unit should appear on the bottom of this conversion factor, since "dollars" appears on the top of the starting value. • Finally, convert cents to nickels. This conversion also involves a simple conversion factor. . This time "cents" should be on the bottom of the conversion factor, S centa since it was on top of the previous conversion factor. • Combining these expressions gives us 1 nickel 5 centa 3432.35 dollars ) (100 cente 1 dollar • Finally, cancel units. Since dollars are divided by dollars, and cents are divided by cents, both of these units can be canceled. Multiplying through gives the final result: 1 nickel 5 centis 3432.35 dollars 100 conts 68, 647…Determine the absolute uncertainty for the calculated value in the following scenarios. Express as (computed result) ± (absolute uncertainty) (units). You measure the volume of a stainless steel sphere by placing it into a100 mL graduated cylinder with an uncertainty of 1 mL, with 20 mL ofwater initially. After the sphere settles, the graduated cylinder now reads22 mL. What is the volume with uncertainty? Please use the formula I posted ! Thank you!
