A car audio system requires a current of 55.0-60.0 mA to run efficiently. Anything more will blow the fuse, and anything less won't provide sufficient power. If your car
battery provides a potential difference of 12.6 V, what is the maximum resistance that
the circuit can have and still work?
Ο 242 Ω
Ο 210 Ω
Ο 229 Ω
Ο 216 Ω

Asteady current of 1 ais flowing through a conducter calculate the number of electrons that flows through conductor in 1second

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) determine the magnitude and direction of projectile velocity at t= 1.3s b) determine the magnitude and direction of projectile acceleration at t=1.3s

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
