A solid metal is often known as having 'an array of positive ions in a sea of electrons'. Write down the electronic structure of magnesium atom and use it to explain what this phrase means. Actually I don't know how to explain it. So I need you to explain...

A 64kg driver gets into an empty taptap to start the day's work. The springs compress 1.9×10−2 m . What is the effective spring constant of the spring system in the taptap?

Stretching DNA. With its double-helix structure, DNA is coiled like a spring. A biophysicist grabs the ends of a DNA strand with optical tweezers and stretches it 26µm producing 1.2pN- tension in the strand. What's the DNA's spring constant?

A 1340 kg car going 21 m/s has to stop suddenly. The driver locks the brakes, and the car skids to a halt in a distance of 67 m . What was the car's acceleration while stopping? How much work was done by friction to stop the car? What is the coefficient o...

Two blocks are connected by a very light string passing over a massless and frictionless pulley (the figure ). Traveling at constant speed, the 20.0- block moves 80.0 to the right and the 12.0- block moves 80.0 downward

Heat Movement Thermal energy is always moving. No matter what substance is heated, there is always another place for the heat to move, unless all available substances are the same temperature and equilibrium is reached. This is particularly true on earth,...

Revolved about the x-axis~ must use: integral 2*Pi*y ds (Eq 1) For ds use: ds = sqrt(1+[F'(x)]^2) dx (Eq 2) sinh(x) dx = cosh(x) = F'(x) sub cosh(x) into Eq 2 and you get: ds = sqrt(1+[cosh(x)]^2) dx now sub ds into Eq 1 integral 2*Pi*y*sqrt(1+[cosh(x)]^2...
