Metabolic syndrome is characterized by all of the following EXCEPT
worty [1.4K]
The term metabolic syndrome defines a group of risk factors which determine your risk for health issues such as heart disease, a stroke and diabetes. Abdominal weight gain (a), elevated blood fat (c) and insulin resistance (d) are all characteristics which will increase your risk of the above health issues. The only characteristic that will decrease your risk of heart disease, diabetes and a stroke is reduced blood pressure (b). If you have any of these negative characteristics, it is important to work at reducing them; thereby, improving your health.

Mean is the same thing as average, so to find this you would add all of the numbers together and divide them by the amount of numbers you added. For example, (6+9+11)/3

Median is the middle number of the list of numbers, but you have to put them in numerical order first. If there is not an exact middle, you would add the middle two together and divide by two.

Mode is the number that occurs most often within the list of numbers.

andre [41]
I believe the correct answer from the choices listed above is the second option. With this information, he was able to conclude that the beam was negatively charged. His cathode ray<span> tube experiments led to a very important scientific discovery, the electron. Hope this answers the question.</span>

Upon being struck by 240-nm photons, a metal ejects electrons with a maximum kinetic energy of 2.97 eV. What is the work functio
Neko [114]

Answer:

Work Function = 3.53 x 10⁻¹⁹ J = 2.2 eV

Explanation:

The work function of the metal metal can be found as follows:

Energy of Photon = Work Function + K.E

hc/λ = Work Function + K.E

Work Function = hc/λ - K.E

where,

h = Plank's Constant = 6.625 x 10⁻³⁴ J.s

c = speed of light  = 3 x 10⁸ m/s

λ = wavelength of photons = 240 nm = 2.4 x 10⁻⁷ m

K.E = Maximum Kinetic Energy = (2.97 eV)(1.6 x 10⁻¹⁹ J/1 eV) =  4.752 x 10⁻¹⁹ J

Therefore,

Work Function = (6.625 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/(2.4 x 10⁻⁷ m) - 4.752 x 10⁻¹⁹ J

Work Function = 8.281 x 10⁻¹⁹ J - 4.752 x 10⁻¹⁹ J

<u>Work Function = 3.53 x 10⁻¹⁹ J = 2.2 eV</u>
