7. A scale is placed on the floor of an elevator. A 60-kg woman enters the elevator when it is at rest and stands on the scale. What does the scale read when (a) the elevator is at rest, (b) the elevator is accelerating upward at 1.75(m)/(s^(2)), (c) the acceleration becomes zero and the elevator moves at the constant velocity of 2.00(m)/(s) upward, (d) the elevator slows down at the rate of 1.75(m)/(s^(2)) before coming to rest, and (e) the cable breaks and the elevator is in free-fall? What is the weight of a body in terms of its weight at the surface of the earth, at a distance from the center of the earth of (a) 1 earth radius, (b) 2 earth radii, (c) 10 earth radii, and (d) at the distance of the moon (3.84\times 10^(8)(m)) ?An airplane is flying in a circle with a speed of 650(km)/(h). At what angle with the horizon should a pilot make a turn of radius 8.00km such that a component of the lift of the aircraft supplies the necessary centripetal force for the turn? 8.Find the centripetal force of a girl on a merry-go-round that turns through one revolution in 40.0s. The radius of the merry-go-round is 3m.

In the Vat Photopolymerization process, a laser of power $P_L$ scans across the resin surface at some speed $V_s$ solidifying resin to a depth $C_d$, the cure depth, assuming that the total energy incident along the scan vector exceeds a critical value called the critical exposure, $E_c$. If the laser scans too quickly, no polymerization reaction takes place; i.e., exposure $E$ is less than $E_c$. Both $E_c$ and $D_p$ must be determined experimentally and is information provided by the resin's vendor. Given Parameters $E_c$= critical exposure = exposure at which resin solidification starts to occur [mJ/mm²]. $D_p$ = depth of penetration of laser into a resin until a reduction in irradiance of 1/e is reached = key resin characteristic [mm]. Parameters to be calculated $E_{max}$= peak exposure of laser shining on the resin surface (center of laser spot) [mJ/mm²]. $C_d$ = cure depth = depth of resin cure as a result of laser irradiation [mm]. $L_w$= resin cure line width [mm]. $W_o$= radius of laser beam focused on the resin surface [mm]. $P_L$= output power of laser [W]. $V_s$= scan speed of laser [mm/s] or [m/s]. For a process with the following specifications: • $P_L$= 1,000 mW • $W_o$= 0.135 mm • $D_p$ = 0.17 mm • $E_c$= 5 mJ/cm² Calculate the following parameters: For a desired $C_d$ = 0.25 mm, $V_s$=______[m/s].

Q9 The government of Junta took Fuel Safe Corp., a domestic energy firm, into state ownership to save the company from bankruptcy. However, the other private competitors in the energy industry were enraged by this decision. As a result, the government had to reduce the tax burden on all private energy firms so that both the state-owned enterprise and private firms could coexist. What type of economy does this portray?
