Consider the standard equation for force, F = ma. In a centripetal system, the acceleration a is given by a = v^2/r. Plugging this in to the equation for force yields F = mv^2/r; hence to calculate centri...

F = 10NA = 1x10^-6 m^2Therefore, Stress = 10 MPaStrain = Stress / E = 10 / 200 x10^3 = 5x10^-5 delta L = strain x length = 5x10^-4 cm = 5 micrometers

This problem should be split into two parts, the time it takes the ball to reach its maximum point, and the time it takes it to fall to the ground from the maximum point.part 1) We can calculate the balls...

To calculate the deceleration of the car we must re-arrange F=ma to make a the subject of the formula, a = F/m. We then put in the numbers to get, 3000/1500, to get a deceleration of 2 ms^-2.
To get...

The key word to note in this question is that the expansion is isothermal and that we have a closed system. This means that the expansion must happen at a constant temperature (isotherma...
