(7 points) unique.py: A number in a list is unique if it appears only once. Given a list of

random numbers, print the unique numbers and their count. Print the duplicate numbers and

their count.

Sample runs:

Enter the size of the list : 7

Two 50 ?? long, thin parallel straight wires (grey) are connected at their ends by metal springs. The mass of each thin wire is 1.0 ?. The upper wire is connected to the ceiling by (non-conducting) stiff rods. Each spring has an equilibrium length of 5.0 ?? and a spring constant of ? = 0.50 ?/?. A steady current ? runs clockwise through the wire-spring loop as indicated by the arrow. At equilibrium, the lower rod hangs at a level 6.0 ?? below the upper wire. Find the magnitude of the current. You may ignore the magnetic fields generated by the springs, and you may approximate the magnetic fields generated by the wires as those from long, straight wires

Two blocks, of weights 3.5 N and 5.8 N, are connected by a massless string and slide down a 39° inclined plane. The coefficient of kinetic friction between the lighter block and the plane is 0.064; that between the heavier block and the plane is 0.30. Assuming that the lighter block leads, find (a) the magnitude of the acceleration of the blocks and (b) the tension in the string.

In the figure below, the hanging object has a mass of m₁ = 0.410 kg; the sliding block has a mass of m₂ = 0.765 kg; and the pulley is a hollow cylinder with a mass of M = 0.350 kg, an inner radius of R₁ = 0.020 0 m, and an outer radius of R₂ = 0.030 0 m. Assume the mass of the spokes is negligible. The coefficient of kinetic friction between the block and the horizontal surface is ?_k = 0.250. The pulley turns without friction on its axle. The light cord does not stretch and does not slip on the pulley. The block has a velocity of v_i = 0.820 m/s toward the pulley when it passes a reference point on the table.

(a) Use energy methods to predict its speed after it has moved to a second point, 0.700 m away.
m/s

(b) Find the angular speed of the pulley at the same moment.
rad/s

Q: Why do you want to be a CPO peer educator? CPO stands for Center for Prevention outreach. I would love someone with experience to provide insights to their personal story.

Q: What experience do you have talking about health and wellness with your peers (high school or college)? Again I hope someone with experience provide insights.

Much appreciation, thank you!

Taking a test on "Inheritance" in C++ tomorrow. So far we have learned about classes, structs and arrays and strings. We will be provided with coding prompts and have to hand write codes that show examples of inheritance (most likely including some of the earlier concepts as well).

I would like some code examples such as this to study and look over with comments please.

At 700 K acetaldehyde decomposes in the gas phase to methane and carbon monoxide. The reaction isCH3CHO(g)?CH4(g)+CO(g)
A sample of CH3CHO is heated to 700 K and the pressure is measured as 0.20 atm before any reaction takes place. The kinetics of the reaction are then followed by measurements of total pressure and these data are obtained:

Rate law --> Rate=??PCH3CHO?t=4.510?4atm?1?s?1PCH3CHO2

Find total pressure after 1.1710⁴s
