) The one-line diagram of a three-phase power system is as shown in Figure 2. Impedance are marked in a per-unit on a 100-MVA, 400-kV base. The load at bus 2 is S-15.93 MW-j33.4 Mvar and at bus 3 is S77 MW+j 14 Mvar. It is required to hold voltage at bus 3 at 400 +j0 kV. Working in per-unit, determine the voltage at buses 2 and 1 j0.5 puj0.4 pu S2 Figure 2 S3
A laser beam is incident on a 45°–45°–90° prism perpendicular to one of its faces as shown in the figure above. The transmitted beam that exits the hypotenuse of the prism makes an angle of θ = 19.8° with the direction of the incident beam. Find the index of refraction of the prism.
Each of the space shuttle's main engines is fed liquid hydrogen bya high-pressure pump. Turbine blades inside the pump rotateat 617 rev/s. A point on one of the blades traces out acircle with a radius of 0.020m as the blade rotates. a) What is themagnitude of the centripetal acceleration that the blade mustsustain at this point? b) Express this acceleration as amultiple of g = 9.80m/s2 .
A researcher is estimating the effect of studying on the test scores of student’s from a private school. She is concerned, however, that she does not have information on the class size to include in the regression. What effect
would the omission of the class size variable have on her estimated coefficient on the private school indicator variable? Will the effect of this omission disappear if she uses a larger sample of students?
Victory Company signed a 6-year lease for a store space on January 1, 2017. The entity has an option to renew the lease for an additional 4-year period on or before January 1, 2020. During January 2019, the entity made substantial improvement to the store. The cost of the improvement was P1,080,000 with an estimated useful life of 10 years. On December 31, 2019, the entity intended to exercise the renewal option. The entity has taken a full year depreciation on this leasehold improvement for 2019. On December 31, 2019, what is the carrying amount of the leasehold improvement?
An entity computed its pre-tax income in its GAAP compliant books at P2,450,000 while its income per income tax return properly computed at P2,850,000. There has been a temporary difference causing the discrepancy between the two amounts. The tax rate is 30%. How much is the Deferred Tax Liability of the company to be presented in its statement of financial position? *
To raise operating funds, Pepero Company sold its equipment on March 31, 2019 for P470,000 and immediately leased the equipment back. The fair value of the asset is P700,000 and the equipment has a carrying value of P650,000. The annual rental payments of P100,000 is significantly lower than the fair rental of P125,000 for this type of equipment. Lease term is 12 years out of total life of 25 years. How much loss should be deferred beyond 2019 as a result of this leaseback transaction? *
Lax Company at the end of 2019, its first year of operations, prepared a reconciliation between pretax financial income and taxable income as follows: Pretax financial income P900,000; Estimated litigation expense P1,200,000; Extra depreciation for taxes (P1,800,000); Taxable income P400,000. The estimated litigation expense of P1,200,000 will be deductible in 2020 when it is expected to be paid. Use of the depreciable asset will result in taxable amounts of P600,000 in each of the next three years. The income tax rate is 30% for all years. Income tax payable is *
