An irregularly shaped piece of metal has a weight of 0.882 N. It is suspended from a scale, which reads 0.735 N when the piece is submerged in water. What are the volume and density of the piece of metal?
This causes an expansion, which happens adiabatically and isothermally. How much does the volume increase (in cubic centimeters)?
A particle moves along the x axis. It is initially at the position 0.270 m, moving with velocity 0.140 m/s and acceleration 20.320 m/s2. Suppose it moves as a particle under constant acceleration for 4.50 s. Find its position and (d) its velocity
Knowing that Paisson's ratio = 0.3 and E = 200 GPa, determine (a) the elongation of the rod in a 200-mm gage length (b) the change in diameter of the rod.
Knowing that E= (29 x 10^6) psi and Poissons Ratio = .30, determine the initial force in the bolt, if the diameter is observed to decrease by (0.5 x 10^-3) in.
Calculate the force (magnitude and direction) exerted on the particle by each of the three fields when it is (a) stationary, (b) moving along the +x axis at a speed of 345 m/s, and (c) moving along the +z axis at a speed of 345 m/s.
Without doing detailed calculations, sketch the curve for thetitration of 30.0 mL of 0.10 M NaOH with 0.10 M HCl. Indicate the approximate pH at the beginning of the titration and at the equivalence point.
