What is the relative uncertainty of an area of a circle (in percentage, one significant digit) if the diameter is measured to be 4.0 cm and the uncertainty in the diameter measurement is 0.1 cm?
A rectangular solid (with a square base) has a surface area of 73.5 square centimeters. Find the dimensions that will result in a solid with maximum volume. cm (smallest value) cm cm (largest value)
Problem 1 (About uncertainty in addition and subtraction) You are trying to measure the height of a table using a 30-cm ruler. Since the ruler is not long enough, you do the measurement on 3 steps and you obtain the following results di = 30.0 +0.1 cm dz = 30.0 + 0.1 cm dz = 16.6 + 0.1 cm What is the total height of the table, di + d2 + dz?
19. Minimizing surface area. Mendoza Soup Company is constructing an open-top, square-based, rectangular metal tank that will have a volume of 32 ft. What dimensions will minimize surface area? What is the minimum surface area?
This is about using proper number of significant

(g17 2 1-10-2 Your answer cannot be understood or graded. More Information ± x cm2 0.4 (b) what if? If the thickness of the board is (1.1 ±。2) cm, what is...
suppose you measure the density of a material and find it to be 3.1 g/cm3 with an uncertainty of 0.1 g/cm3. (The uncertainty may arise from an uncertainty built into the scale. From this measurement, what can you claim about the identify of the material?
answer question 6 pls
Water Volume and Mass 1. Position a meterstick vertically on a flat surface, such as a wall or the side of a lab bench. Be sure Unit for y-variable- y-axis the metric scale of the meterstick is on the outside and secure the meterstick to the wall or lab bench with two strips of masking tape. 200Scale for y-variable Graph Title 2. Drop a ball as close as possible to the meterstick and measure (a) the...
I) You want to find the volume of a mtal sphare (Note: the formula for the volume of a sphere is V--πr. where r is the radius of the sphere). You measure the radius of the sphere to be r-2.18 cm, with a measurement uncertainty of± 0.02 cm. What is the volume of the sphere as well as the corresponding uncertainty of the calculated volume? 2) You measure the mass of the same sphere used in qesio, and find that...
