Round off the following numbers to three significant figures: (a) 58 342 m, (b) 68.534 s, (c) 2553 N, and (d) 7555 kg.
(a)
To Round off:
The number 58342 m to three significant figures.
Answer to Problem 1P
The round off for number 58342 m to three significant figure is
Explanation of Solution
Given:
The given value is
Explanation:
A significant figure is defined as a method that is used to indicate an uncertainty in experimental or calculated values. Significant figures are the vital digits that are identified with certainty. Certainty is indicated first in a number followed by uncertainty.
For example: If a result is 12.3 m, 12 is certain and 3 is uncertain.
Round off the number to three significant figures.
Write the three significant figures formula.
Conclusion:
Round off the number 58342 m to three significant figures.
Thus, the round off for number 58342 m to three significant figures is

- ### Superheated steam powers a steam turbine for the production of electrical energy. The steam expands in the turbine and at an intermediate expansion pressure (0.1 Mpa) a fraction is extracted for a regeneration process in a surface regenerator. The turbine has an isentropic efficiency of 90% Design the simplified power plant schematic Analyze it on the basis of the attached figure Determine the power generated and the thermal efficiency of the plant ### Dados in the attached imagesarrow_forwardThe machine below forms metal plates through the application of force. Two toggles (ABC and DEF) transfer forces from the central hydraulic cylinder (H) to the plates that will be formed. The toggles then push bar G to the right, which then presses a plate (p) into the cavity, thus shaping it. In this case, the plate becomes a section of a sphere. If the hydraulic cylinder can produce a maximum force of F = 10 kN, then what is the maximum P value (i.e. Pmax) that can be applied to the plate when θ = 35°? Also, what are the compressive forces in the toggle rods in that situation? Finally, what happens to Pmax and the forces in the rods as θ decreases in magnitude?arrow_forwardDetermine the magnitude of the minimum force P needed to prevent the 20 kg uniform rod AB from sliding.
