Please get up off your knees ... it's unbecoming.

The statement is true.

The vast, vast, vast majority of substances we come in contact with every day are compounds, made of the combinations of different atoms.

Some examples are ...

... Water (Hydrogen and Oxygen)

... Salt (Sodium and Chlorine)

... Natural gas, Methane, Propane, Octane, Ethane, Hectane, Heptane, Butane, Rubber (all of these are combinations of different numbers of Carbon and Hydrogen atoms)

... Carbon dioxide (Carbon and Oxygen)

... DNA (Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorus)

... Rust (Iron and Oxygen)

... Sugar, Glucose, Sucrose, Alcohol, Ethanol, Vinegar, Acetic acid, Citric acid, Camphor (all of these are combinations of different numbers of Carbon, Hydrogen, and Oxygen atoms)

... Baking soda (Sodium, Carbon, Hydrogen, and Oxygen)

... Ammonia (Nitrogen and Hydrogen)

... Sulfuric acid (Hydrogen, Sulfur, and Oxygen)

... Nitric acid (Hydrogen, Nitrogen, and Oxygen)

This is what i found on google “what happens to the bond angle when you add or remove an electron domain? the bond angle decreases as you add domains 5. can you force the atoms into new configurations by pushing atoms around? note: we can think of a bond or a lone pair of electrons as a “domain” of electrons.” i hope this you

Answer from: Quest

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm. the wire diameter is d = 0.9 mm. the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2) in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
