The theory of plate tectonics explains many geological events, including

Physics
1 answer:
OLga [1]3 years ago
5 0

Answer:

D

Explanation:

The crust of the Earth is broken into many pieces called plates. The plates "float" on the soft, plastic mantle which is located below the crust, aka asthenosphere

An account voltage is connected to an RLC series circuit of resistance 5ohms, inductance 3mH, and a capacitor of 0.05f. calculat
Nesterboy [21]

Answer:

12.99 Hz

Explanation:

Resonance is said to occur in an RLC circuit when maximum current is obtained from the circuit. Hence at resonance; XL=XC and Z=R.

XL= inductive reactance, XC= capacitive reactance, Z= impedance, R= resistance

The resonance frequency is given by;

fo= 1/2π√LC

L= 3×10^-3 H

C= 0.05 F

π= 3.142

Substituting values;

fo= 1/2×3.142√3×10^-3 × 0.05

fo= 12.99 Hz

Therefore the resonance frequency of the RLC circuit is 12.99 Hz

A cardiac defibrillator stores 1275 J of energy when it is charged to 5.6kV What is the capacitance? O 11.3 pF 96.1 pF O 813 F
Angelina_Jolie [31]

Answer: 813.13(10)^{-7}F

Explanation:

The answer is not among the given options. However, this is a good example of the relation between the energy stored in a capacitor Wand its capacitance C, which is given by the following equation:

W=\frac{1}{2}CV^{2}   (1)

Where:

W=1275J

V=5.6kV=5.6(10)^{3}V is the voltage

C is the capacitance in Farads, the value we want to find

Isolating C from (1):

C=\frac{2W}{V^{2}}   (2)

C=\frac{2(1275J)}{(5.6(10)^{3}V)^{2}}   (3)

Finally:

C=0.000081313F=813.13(10)^{-7}F This is the capacitance of the cardiac defibrillator
