- From last lab, we know that how high up an object is determines how long it takes it to fall. The equation for this is h = 1/2 g t^2. If you rearranged this equation to solve for t, what would you get? * pick whcih answer is best t=1/2sqrt(hg) t = sqrt(2hg) t=sqrt(2g/h) t = sqrt(2h/g) sqrt means square rootThe length of cell A is 9×10^6 m. The length of cell B is 0.0000003 m. What is the ratio of cell A's length to cell B's length? Use pencil and paper. Is it easier to find the ratio when the numbers are expressed in scientific notation or in standard form? Explain your reasoning.I have a couple of follow up questions: 1) Is that 60k^ kgm^2/s, the SI unit for L 2) It wanted an expression as a function of time; so would it be L(t) = 60k, in which case it's 60k no matter what the value of t is? Hopefully, I'm getting across what I mean. Thank you.
- Consider the equation s = s0 + v0t + a0t2/2 + j0t3/6 + S0t4/24 + c0t5/120 , where s is length, and t is time. What are the SI units of (a) s0, (b) v0, (c) a0, (d) j0, (e) S0, and (f) c0? The answers are case sensitive. If you want to insert superscript use the notation "^". For example "m/s^2" means meters per second squared.With a wooden ruler, you measure the length of a rectangular piece of sheet metal to be 12 mmmm.

What is the area of the rectangle? Express your answer in millimeters squared. A=A= ____________ mm2 What is the perimeter of the rectangle? Express your answer in millimeters. P=P= _______________mmI would like some explanation as to how you are able to get the answer. What is the equation that I would have to use to solve this?
- How many minutes would it take to travel a distance of 7000 meters if you are traveling at a speech of 60 meters per second? Use the formula distance = speed x time. In lecture, we were given the formula V= λ/T. Sometimes we have to manipulate this formula to answer the question we are being asked. 4a. How do we manipulate the formula V= λ/T if we are given a problem where we need to find T? 4b. How do we manipulate the formula V= λ/T if we are given a problem where we need to find λ?A. Unit Conversion. Show your complete solution. Write your answers up to 3 significant figures. Recall: 1 Gy = 100 rad, 1 Sv = 100 rem 1. 3.5 μGy to mrad 2. 5.0 mrad/h to mGy/h 3. 45.0 mrem to μSvCheck Your Understanding We know horn Figure 1.4 that the diameter of Earth is on the order of 107m , so the order of magnitude of its surface area is 1014m2 . What is that in square kilometers (that is, km2)? (Try doing this both by converting 107m to km and then squaring it and then by converting 1014m2 directly to square kilometers. You should get the same answer both ways.)
- YOU MUST SHOW HOW YOU DID THE CONVERSION! Use the above example as a model for your work to show a clear path to answer. A flatbed truck is 35 feet 6 ½ inches long. Convert that distance into mm. 1 inch = 2.54 cm or 1 cm = 0.3937 inch My height is 6 feet 1 inches. I first convert the feet to inches and then add the additional inch. 2.54 cm 10 mm. Convert 120 m/sec into ______ ft/min. Given 1 meter = 3.28 ft, and 1 min = 60 sec can you show me step by step and how to do on calculatorWhat's the correct answer? Can you explain in detail please.
