- In the answer, it gives a formula f-ff=m(0) and afterwards simplies into 120 - ff = 0 and further into ff=120N. My question is how do you not have to divide by 0 to finish the equation if that makes sense. To simply further why are we able to ignore the m(0) portion?Using your values for 7, calculate the average period Ibar (I) and its standard error. How does the error on the average period /bar (T) compares to the errors on the periods, I? What can you do to reduce the uncertainty on /bar (T)? What can you do to reduce the uncertainty on 7 ?

Then the family drives 610 km south, 310 km east, and 410 km north. Where will the Matons end up in relation to their starting point? Give direction only, directly East is 0 degrees and the order goes counter clock wise (North is 90 degrees, West is 180 degrees, South is 270 degrees).
- For (b), why do we divide the (100Wx8h) by (103Wh)? I get that we need to cancel out the Wh, but why do we divide by 103 specifically?The 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.Imagine you derive the following expression by analyzing the physics of a particular system: v2=v20+2axv2=v02+2ax. The problem requires solving for xx, and the known values for the system are a=2.55meter/second2a=2.55meter/second2, v0=21.8meter/secondv0=21.8meter/second, and v=0meter/secondv=0meter/second. Perform the next step in the analysis.
- An ant is crawling along a straight wire, which we shall call the z axis, from A to B to C to D (which overlaps A), as shown in the figure below. (Figure 1) O is the origin. Suppose you take measurements and find that AB is 44 cm, BC is 20 cm,and AO is 4 cmThe temperature at a point (x, y) is T(x, y), measured in degrees Celsius. A bug crawis so that its position after t seconds is given by where x and y are measured in centimeters. The temperature function satisfles T3, 6) 2 and T(3, 6) -7. How fast is the temperature rising on the bug's path after 2 seconds? (Round your answer to two decimal places.) C/s Need Help? Read Watch Master tHey, I'm really so sorry for leaving this out, but I completely forgot to tell you that I need the answer in the amount of years it takes. That's totally on me, I apologize. Also, I can't tell if the dot between the two 2s in the answer is a multiplication symbol or a decimal point.
