Q#2: Put sign (V) for the correct answer and wrong sign (X) for the wrong answer:...
If a is acceleration, v is velocity, x is position, and t is time, then check the validity (wrong or correct) of the following equations using dimensional analysis: a) t2 = 2x/a b) t = x/v c) a = v/x d) v = a/t ALSO , The term 1/2 PV^2 rv2 occurs in Bernoulli’s equation in Chapter 15, with P being the density of a fluid and v its speed. Find the dimensions of 1/2 PV^2 Thank you in advance...
Need detailed answer, big thanks! 2. A three-phase A-connected, 50 Hz, 400 V, 4 poles, induction motor has the following parameters for the exact equivalent circuit (per phase): R, 0.7 Q; x 1.4 Q; x 1.2 ; xy 50 -1600 ; R 0.54 2. The rotational loss is 300 W at rated current. The motor is supplied by an 8-pole synchronous generator, Y-connected, with a synchronous reactance of x 1.5 (per phase). The motor is operating at rated frequency, rated...

[2] Your answer is partially correct. Try again. An electrically neutral model airplane is flying in a horizontal circle on a 3.5-m guideline, which is nearly parallel to the ground. The line breaks when the kinetic energy of the plane is 50 1. Reconsider the same situation, except that now there is a point charge of +q on the plane and a point charge of -q at the other end of the quideline. In this case, the line breaks when...

choose correct answer. no explanation needed QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...
