The energy in an oscillating lc circuit containing a 1.57 h inductor is 5.96 μj. the maximum charge on the capacitor is 205 μc. for a mechanical system with the same period, find the (a) mass, (b) spring constant, (c) maximum displacement, (d) maximum speed.

in physics zero. in muscle fatigue could be high

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
