Determine the distance h it must descend for it to reach a speed of v2 = 2 m/s. Also, what is the angle of descent theta, that is, the angle measured from the horizontal to the tangent of the path.
Diamond has a face-centered cubic unit cell, with four more Catoms in tetrahedral holes within the cell. Densities of diamondsvary from 3.01 g/cm3 to 3.52 g/cm3 because Catoms are missing from some holes.
A square loop of wire with sides of length 40 cm experiences a uniform magnetic field perpendicular to its area. (a) If the field's strength is initially 100 mT and it decays to zero in 0.010 s, what is the magnitude of the average emf induced in
An elevator starts from the 1st floor with 8 passengers and may stop at the 2nd or the 3rd floor or both. Suppose that each passenger may get out of the elevator at either of the 2nd or the 3rd floor. Note that 8 passengers are different. How many
Assuming that the flow is adiabatic and that the kinetic energy of the steam at the inlet is negligibly small, determine the inlet temperature if the inlet pressure is 300 kPa.
A student makes a simple generator by using a single square loop 10 cm on each side. The loop is then rotated at a frequency of 60 Hz in a magnetic field of 0.015 T. (a) What is the maximum emf output? (b) If she wanted to make the maximum emf out
Find the total number of ways to have n lattices containing one ball each, and the other N-n lattices containing no balls. Note that in this part, the n lattices may be any n lattices out of the N lattices in total.
Estimate the maximum power that can be transmitted for a seven (7) year design life of 40 hours/week for 48 weeks/year with 99.9% reliability. Consider tooth bending failure only, using a factor of safety of 1.4.
