A vertical cylinder ofcross-sectional area 0.050 \(\displaystyle{m}^{{2}}\) is fitted with atight-fitting, frictionless pistion of mass 5.0 kg. If there are 3.0 mol of ideal gas in the cylinder at 500 K, determine the height"h" at which the postion will be in equilibrium.
the height "h" at which thepostion will be in equilibrium can be found by using \(\displaystyle{h}={\frac{{{V}}}{{{A}}}}\)
according to ideal gaslaw \(V=\frac{nRT}{P} n = 3.0 mol , T= 500 K , R = 8.31 J/ mol .K\)
Where \(\displaystyle{P}_{{{a}{t}{m}}}+{P}_{{{g}{a}{u}\ge}}\)
\(\displaystyle{P}_{{{a}{t}{m}}}={1.013}\cdot{10}^{{5}}\) Pa
\(\displaystyle{P}_{{{g}{a}{u}\ge}}={\frac{{{F}}}{{{A}}}}\)
\(\displaystyle={\frac{{{m}{g}}}{{{A}}}}\)
where m is mass =5.0kg, \(\displaystyle{g}={9.8}\frac{{m}}{{s}^{{2}}}\)
A is area \(\displaystyle={0.050}{m}^{{2}}\)
plug the values in corresponding equations and calculatea for the answer

Problem: From what maximum height can a 75 kg person jump w/obreaking the lower leg bone on either leg? Ignore air resistance and assume the CM of the person moves a distance of 0.60m from the standing to the seat position (that is, in breaking the fall). Assume the breaking strength (force per unit area) of bone is \(\displaystyle{170}\times{10}^{{6}}\ \frac{{N}}{{m}^{{2}}}\) and its smallest cross sectional areais \(\displaystyle{2.5}\times{10}^{{-{4}}}\)

A long, straight, copper wire with a circular cross-sectional area of \(\displaystyle{2.1}{m}{m}^{{2}}\) carries a current of 16 A. The resistivity of the material is \(\displaystyle{2.0}\times{10}^{{-{8}}}\) Om.
a) What is the uniform electric field in the material?
b) If the current is changing at the rate of 4000 A/s, at whatrate is the electric field in the material changing?
c) What is the displacement current density in the material in part (b)?
d) If the current is changing as in part (b), what is the magnitude of the magnetic field 6.0cm from the center of the wire? Note that both the conduction current and the displacement currentshould be included in the calculation of B. Is the contribution from the displacement current significant?

A 0.30 kg ladle sliding on a horizontal frictionless surface isattached to one end of a horizontal spring (k = 500 N/m) whoseother end is fixed. The ladle has a kinetic energy of 10 J as itpasses through its equilibrium position (the point at which thespring force is zero).
(a) At what rate is the spring doing work on the ladle as the ladlepasses through its equilibrium position?
(b) At what rate is the spring doing work on the ladle when thespring is compressed 0.10 m and the ladle is moving away from theequilibrium position?

Three building materials, plasterboard [k = 0.30 J/(s m Co)], brick [k = 0.60 J/(s m Co)], and wood [k = 0.10 J/(s m Co)], are sandwiched together as the drawing illustrates. The temperatures at the inside and outside surfaces are \(\displaystyle{25.1}^{\circ}\) C and \(\displaystyle{0}^{\circ}\) C, respectively. Each material has the same thickness and cross-sectional area. Find the temperature (a) at the plasterboard-brick interface and (b) at the brick-wood interface.
