An 80 kg volleyball player lands from a jump and tries to stop her forward motion. The normal contact force exerted by the floor
Paladinen [302]

Answer:

The answer to the question is

The resultant ground reaction force exerted by the floor on the volleyball player's shoes = 2088.06 N

Explanation:

To solve the queston we list out the variables thus

Mass of volley ball player = 80 kg

Normal force exerted on her shoes by the floor N =2000 N

friction force, f, exerted on her shoes backwards = 600 N

The resultant ground reactive force, R, is given by

R² = N² + f² = 2000² + 600² =  4000000 + 360000 = 4360000

Therefore R = √(4360000) =  2088.06 N

The direction of the force = atan (2000/600) = 73.3 ° clocwise or 106.699 ° counter clockwise

Why is the wavelength of 633 nm used to analyze the standard solutions and drink samples?
RUDIKE [14]

Answer:

Corresponding with orange light, is the wavelength that blue solutions absorb the most.

Explanation:

If light is diffused through a solution of a given color, emerges of light from another wavelength is consumed and fades away. However, the wavelength of light relating to the color of such a solution is transferred. The color of the light is consumed is usually the contrasting one being transferred. As seen in a color wheel where, blue complement orange, red complement green, and yellow complement violet.

Thus, for a blue substance in solution, its complementary color is said to be orange, Given that the wavelength of orange color varies from 600 - 640 nm where it's maximum absorbance is approximately 633 nm. This wavelength is what is employed when analyzing the standard solutions and drink samples.

Hydrogen gas is collected over water in an inverted buret. If the atmospheric pressure is 745 mm Hg, the vapor pressure of water
Varvara68 [4.7K]

Answer:

P_{H_2}=727mmHg

Explanation:

Hello there!

In this case, according to the given data, it is possible to infer that the gas mixture lies on the 15.0 cm-high column of water, so that the total pressure or atmospheric pressure is given by:

P_{atm}=P_{water}+P_{H_2}

Thus, since the atmospheric pressure is 745 mmHg and the vapor pressure of water is 18 mmHg, the pressure of hydrogen turns out to be:

P_{H_2}=P_{atm}-P_{water}\\\\P_{H_2}=745mmHg-18mmHg\\\\P_{H_2}=727mmHg

Best regards!

Which pH value would a very acidic solution have?<br> a. 0<br> b. 6<br> c. 9<br> d. 14
Artist 52 [7]
The answer is A. 0 because 9 and 14 would be a pH of basic solutions because they are greater than 7; 0 and 6 are acidic because they are less than 7 but zero is smaller than 6 so it is the most acidic
