The followings are the measurements from one group of students: M1=127.01 g, M2=49.40 g, Xi=33.90 cm, Xf=87.90 cm, Δt = 1.38 sec, what should be their μk value?  Enter the result with correct significant figures.

If n=5, how many values are possible for Ml?

The mass of a block of wood is (3.15 ± 0.05) kg and its volume is (6.35 ± 0.02) x 103 cm3. Using the relationship: density = mass/volume, solve for density and find the uncertainty in density of wood in kg/m3 units.

What is the sum of 44.06005 s, 0.0598 s, and 1103.4 s? Answer the question with correct number of significant figures. Note: use the rule for addition and subtraction explained in the book.

Engineer A found that the dimension of a small rectangular block were 1.5 cm X 1.3 cm. x1.0 cm. Multiplying these two numbers together, John recorded the volume of the block as 1.950cm³. Engineer B used a micrometer caliper on the same block and found the dimension to be 1.485 cm X 1.314 cm X 0.986 cm. He recorded the volume of the block as 1.92cm3. Which is more reliable in terms of the data from which it was calculated? Why?

Starting with the definition that 1.00 in. = 2.54 cm, find the number of kilometers in 3.107 miles, and the number of feet in 1.00 km.

Convert the following measurements to metric units with power-of-ten prefixes. Do not use scientific or engineering notation. Numeric values must range from 1 to less than 1000. Metric prefixes, which are case-sensitive, must be one of the following: M, m, c, k, or µ. (You may use lower-case 'u' in place of 'p'.) Example: 2.00 × 105 m = 200 km Enter the numeric value in the first box, and enter the metric prefix in the second box. a. 3.51 x 10-5 L = b. 7.98 x 108 J = C. -0.000230 W = - W d. 11,200 K = K (note: upper-case 'K' is the abbreviation for the temperature unit 'kelvin')

In the following calculations, be sure to express the answer in standard scientific notation with the appropriate number of significant figures. 6.477 × 10 m² 4.7036 x 102 m x 10

Pls help ASAP. Pls give the significant figures of each of the answer.

Carry out the following arithmetic operations. (Enter your answers to the correct number of significant figures.) (a) the sum of the measured values 521, 34.6, 0.90, and 9.0 (b) the product 0.0052 ✕ 425.6 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. (c) the product 17.30 ✕ π
