When a branch contains a current source, the number of mesh equations is reduced, thus simplifying the mesh analysis technique True False

assume that the voltage of the current is given by V = 170 sin (120πt), where t is in seconds. Find thewattage ratingmaximum wattageV2of each electric device ifthe current flowing through the device is I amps.A quarterback throws a ball with an initial velocity of v, feet per second at an angle 0 with the horizontal. The horizontal distance x in feet that the ball is thrown is modelled by a equation x=vo/16sin theta cos theta.for a fixed vo.find the angle that produces the maximum distance x.

Hand by written ans. With all part solution

PLEASE VERIFY IF THESE ARE ALL CORRECT. thank you!

A family Light bulb of loow, a fan of loow, uses an elechric heater of loo w, each for 8 hours daily. LF the cost of electricity is o-olo Riyd Per unit, what is the expenditure for the Gam ily Per day electricity? on

During an experiment to verify Ohm's law, the current and resistance of a circuit are measured. [Resistance is measured in Ohm () and current in Ampere (A)]. www R +, Battery The measured value of the current is I 3±0.1 A and that of the resistance is R = 17+0.3 . The voltage applied (in Volts) can be calculated using the formula, V = IR. Calculate the, a) Voltage applied in the circuit (in Volts) = b) Fractional uncertainty in the voltage = c) Absolute uncertainty (in Volts) in the voltage =

Determine the I in the figure using Mesh Analysis.

Please type the answer clearly by computer thanks

250 mA and .2 sec creates a good radiograph of a lateral thoracic spine withappropriate exposure to the IR. The technologist wants to modify this technique to give the patient time to breathe during the exposure. If the time is changed to 2 seconds, what new mA will maintain exposure?

how do you solve for t in tcos0
