1. f(x)= x+1/x ; g(x)= x-2/x
2. f(x)= -2/x ; g(x)= x+1/x-3

Please leave an answer with the step-by-step solutions.
thanx. this is the sum of functions.

Two 10 N weights are attached to a spring scale as shown below. Does the scale read 0, 10, 20 N, or any other reading?

(Would it read any differently if one of the ropes were tied to the wall instead of to a hanging 10 N weight?)

A person climbs down 7 steps when he sees his professor starting to climb from the bottom of the stairs. They pass each other and moving down he finds that he has 4 more steps to go when his prof reached the top. Considering prof takes 2 steps to one step of the person, calculate no. of steps.

The block below is at rest on the ground with a vector drawn that shows its weight.

How would you complete the vector diagram showing another vector that results in zero net force, and what is the conventional name of that vector?

The gas inside a balloon will always have a pressure nearly equal to atmospheric pressure, since that is the pressure applied to the outside of the balloon. You fill a balloon with helium (a nearly ideal gas) to a volume of 0.580 L at a temperature of 18.5 degrees C. What is the volume of the balloon if you cool it to the boiling point of liquid nitrogen, 77.3 K?

What volume is occupied by this amount of water? The molar mass of water is 18.0 g/mol.

Imagine the molecules to be, on average, uniformly spaced, with each molecule at the center of a small cube. What is the length of an edge of each small cube if adjacent cubes touch but don't overlap?

and finally....How does this distance compare with the diameter of a molecule?

A cylinder with a height of 1.30 m and an inside diameter of 0.100 m is used to hold propane gas (molar mass 44.1 g/mol) for use in a barbecue. It is initially filled with gas until the gauge pressure reads 1.4×10^6 Pa and the temperature is 23.0 degrees C. The temperature of the gas remains constant as it is partially emptied out of the tank, until the gauge pressure reads 2.4×10^5 Pa.

Calculate the mass of propane that has been used.
Use 8.31 J/(mol*K) for the ideal gas constant.

A gas undergoes two processes. In the first, the volume remains constant at 0.250 m^3 and the pressure increases from 2×10^5 Pa to 6×10^5 Pa. The second process is a compression to a volume of 8.00×10^(−2) m^3 at a constant pressure of 6×10^5 Pa.

Find the total work done by the gas during both processes in joules.

A gas in a cylinder is held at a constant pressure of 2.2×10^5 Pa and is cooled and compressed from a volume of 1.79 m^3 to 1.30 m^3. The internal energy of the gas decreases by 1.37×10^5 J.
Find the work done by the gas.

Find the absolute value |Q| of the heat flow into or out of the gas.
