Q. Rank the magnitudes of the forces exerted on the following particles from largest to smallest. In your ranking, display any cases of equality. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)(a) an electron moving at 1 Mm/s perpendicular to a 1-mT magnetic field(b) an electron moving at 1 Mm/s parallel to a 1-mT magnetic field(c) an electron moving at 2 Mm/s perpendicular to a 1-mT magnetic field(d) a proton moving at 1 Mm/s perpendicular to a 1-mT magnetic field(e) a proton moving at 1 Mm/s at a 45° angle to a 1-mT magnetic field
Calculate the dc voltage applied to the circuit.
Inversely proportional to the square of the fields
A sealed tank containing seawater to a height of 11.1 also contains air above the water at a gauge pressure of 2.95. Water flows out from the bottom through a small hole.
The origin of the coordinate system and with a label at their heads. Two of these vectors are given in terms of the unit-vectors I and j as
Three single-phase step-up transformers rated at 10MVA, 4.6kV/13.8kV are connected in Wye-Delta configuration. The three transformers are used to feed a 20MVA load at 0.9 p.f. With an efficiency of 96%. Find the secondary line voltage.
