MATH-4 lvls of measurement-CHECK MY ANSWERS.A 0.021 M solution of C6H5CH2COOH has a pH of 2.99. Phenylacetic acid (C6H5CH2COOH) is one of the substances that accumulates in the blood of people with phenylketonuria, an inherited disorder that can cause mental retardation or even death. With what velocity does the object hit the ground? This typeĪn electrochemical cell is based on these two half-reactions: Ox: Sn(s) → Sn2+(aq, 1.74 M) + 2 e- Red: ClO2(g, 0.120 atm) + e- → ClO2-(aq, 1.44 M) Calculate the cell potential at 25☌ E Sn>Sn2+ = -.14 E ClO2 =. Use a(t) = -32 ft per second squared as the acceleration due to gravity.An object is thrown vertically downward from the top of a 480-ft building with an initial velocity of 64 feet per second.
After it is released, it moves up, reaches its highest point and moves back down again.

I want to know how to get the that answerĪ toy car is given a quick push so that it moves on an inclined ramp. What is the volume of the gas sample? the answer 2.04. what are the dimensions of each pen that minimize the amount of fence that must be used?Ī gas sample at STP contains 1.15 oxygen and 1.55g nitrogen. (These points correspond to theĪ rancher plans to make four identical and adjacent rectangular pens against a barn, each with an area of 100m^2. The number of mistakes made on each point are shown in the table below. We initialize the parameters to all zero values and run the linear perceptron algorithm through these points in a particular order until convergence. Your assignment is to determine the dimensions (radius and height) of a drum that is to have a volume of 1 cubic meter Project Setup:You work for a company that manufactures cylindrical steel drums that can be used to transport various petroleum products. The concrete for the base costs $4.00 per square foot, the roof material costs $2.00 per square foot, and the material for the sides costs $2.50 per square Find the dimensions of the tank that minimize the surface areaĪ storage shed is to built in the shape of a box with a square base. The coefficient of static friction between theĪ rectangular tank with a square base, an open top, and a volume of 864 ft^3 is to be constructed of the sheet steel. The other end rests against the wall, where it is held by friction as shown in the figure below. One end of a uniform 3.20-m-long rod of weight Fg is supported by a cable at an angle of θ = 37° with the rod. After thermal equilibrium has been reached, the system has a change in temperature The block and the embedded bullet together absorb all the heat generated. Find the minimum value of R if the power taken by R is equal to theĪ 15 g lead bullet is tested by firing it into a fixed block of wood with a mass of 1.05 kg.

The parallel combination is then connected in series with a 6 ohm resistor and connected across a 120 V source. A 30 ohm resistor is connected in parallel with a variable resistance R.
