And electrical substation for your neighborhood includes a transformer that supplies power to your street. It’s input coil has 17,500 wraps and its output coil has 585 wraps. If the input voltage is 75KV what is the voltage of the electrical supply to your

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c
