- I need help with this question. I also don't know what the units should be for the answer. Is it m/s^2 or is it kg m/s^2The length and width of a rectangular room are measured to be 3.885 ± 0.0065 m and 3.2 ± 0.0045 m. In this problem you can approximate the error on a product or quotient of quantities by the sum of the percent error on each quantity.Calculate the floor area of the room in square meters.You purchased 5.2kg of apples from a store. You noticed that they used the smallest division of 4.2 g to weight them. What is the relative error of this weight measurement as a percentage. You want to calculate the area of your dorm which is in a rectangular shape. You measure the length and the width of the room as L= 4.8+(-.01) m, W= 4.4+(-.01) m. What is the absolute error in the area in m^2 units?
- A box containing basketball equipment is sitting on a shipping pallet. The box plus the contents weighs 25 newtons [N], and the pallet weighs 155 newtons [N]. The box can be modeled as a rectangular parallelepiped and has the following dimensions: 3 inches [in] by 15 inches [in] by 20 inches [in]. Assume the pallet is also a rectangle and has the following dimensions: 4 feet [ft] by 3.5 feet [ft] by 0.25 feet [ft]. The box is sitting on the pallet in the configuration shown. You apply 9000 joules [J] of energy to push the box and the pallet across the floor using 160 newtons [N] of force. Determine how far you can push the box and pallet, in units of feet [ft]. You may ignore the friction between the court and the pallet.Langleyville (43 degrees S, 77.6 degrees w) and Cajun Country (25 degrees s, 77.5 degrees w) have almost the same longitude, which means that they are roughly due north-south of each other. Set up all the work to find the approximate distance in miles between the cities assuming the radius of the earth is 4000 miles.Calculate the following and express the answer in the proper number of significant figures: (5.245x0.03x9.0023)/(4.076x0.029x42.3)=

- If g(v) is the fuel efficiency, in miles per gallon, of a car going at v miles per hour, what are the units of g′(90)? What is the practical meaning of g′(55)=−0.54?doesn't that still need to be multiplied by 6?In 1999, NASA lost the Mars Climate Orbiter because one group of engineers used metric units in their calculations while another group used English units. Consequently, the orbiter descended too far into the Martian atmosphere and burned up. Suppose that the orbiter was to have established orbit at 157 km and that one group of engineers specified this distance as 1.57 x 10³ m. Suppose further that a second group of engineers programmed the orbiter to go to 1.57 x 10³ ft. The $125 million Mars Climate Orbiter was lost in the Martian atmosphere in 1999 because two groups of engineers failed to communicate with each other about What was the difference in kilometers between the two altitudes?
