•• A single conducting loop of wire has an area of 7.2 × 10-² m² and a resistance of 110 №. Perpendicular to the plane of the loop is a magnetic field of strength 0.88 T. At what rate (in T/s) must this field change if the induced current in the loop is to be 0.43 A?

I need the answer to three significant figures. That's what I'm having trouble figuring out

Calculate the following and express the answer in the proper number of significant figures: (5.245x0.03x9.0023)/(4.076x0.029x42.3)=

Mary is training for a marathon where she needs to run 13,120m, but she needs to know how many miles that is for her training program, How many miles (rounded to the nearest ones place) will Mary be running for the race? 1m = 3.28ft, 5280ft = 1 mile. Please perform dimensional analysis and show the conversion between all unit factors to find the solution." Please format the two factors as fractions, using the math equation formatting "square root" tool. And then state the final answer.

Which one of the choices below represents the preferred practice regarding significant figures when multiplying the following: (12.00)(0.811)(0.004)?   A. 0.038928   B. 0.038   C. 0.04   D. 0.039   E. 0.0389

(a) A car speedometer has a 6% uncertainty. What is the range of possible speeds (in km/h) when it reads 100 km/h? (There are two answers. Enter the lowest value first and the highest value second. For each answer, enter a number.) lowest          km/hhighest         km/h (b) Convert this to miles per hour. (There are two answers. Enter the lowest value first and the highest value second. For each answer, enter a number.) lowest            mi/hhighest           mi/h

Since 0.254 m = 25.4 cm = 254 mm, we could conclude that unit conversions within the metric units of length can be accomplished by simply shifting the ______ the appropriate number of places.

Which of the following measurements is most precise? (a) 5.00 mm (b) 5.00 cm (c) 5.00 m (d) 5.00 km.
