Plz help plz help plz help meed
Leviafan [203]

Answer:

5106.38 Ω

Explanation:

From the question given above, the following data were obtained:

Current (I) = 0.0235 A

Voltage (V) = 120 V

Resistor (R) =?

From ohm's law,

V = IR

Where:

V => is the voltage.

I => is the current

R => is the resistor

With the above formula, we can obtain the size of the resistor needed as follow:

Current (I) = 0.0235 A

Voltage (V) = 120 V

Resistor (R) =?

V = IR

120 = 0.0235 × R

Divide both side by 0.0235

R = 120 / 0.0235

R = 5106.38 Ω

Thus, the size of the resistor needed is 5106.38 Ω

PLEASE HELP QUICK!!! Electromagnetic Spectrum Activity Worksheet
Vlad1618 [11]

Answer:

The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10²⁵ hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. There is no known limit for long wavelengths, while it is thought that the short wavelength limit is in the vicinity of the Planck length. Extreme ultraviolet, soft X-rays, hard X-rays and gamma rays are classified as ionizing radiation as their photons have enough energy to ionize atoms, causing chemical reactions. Exposure to these rays can be a health hazard, causing radiation sickness, DNA damage and cancer. Radiation of visible light wavelengths and lower are called nonionizing radiation as they cannot cause these effects.

Write the equilibrium constant expression Kc for the following reaction.2H20(g) ---------> O2(g) + 2H2(g) <---------Do not
Komok [63]

Answer:

K_c\text{ = }\frac{[O_2][H_2]\placeholder{⬚}^2}{[H_2O]\placeholder{⬚}^2}

Explanation:

Here, we want to write the equilibrium constant expression

To write this, we raise the concentrations of the reactants and products to the coefficient before them. These concentrations are represented by square brackets in which the chemical formula of the compound is placed

We place the representation of the products over that of the reactants

We have the expression written as follows:

K_c\text{ =  }\frac{[H_2]\placeholder{⬚}^2[O_2]}{[H_2O]\placeholder{⬚}^2}
