Jose’s lab instructor gives him a solution of sodium phosphate that is buffered to a pH of 4. Because of an error that he made w

hile calibrating the pH meter, Jose’s measurements of the pH of the sodium phosphate solution are 5.4, 5.4, and 5.4. Which statement best describes his results?

I am thinking that maybe the problem is not with the calibration. It might be that the buffered solution is already expired since at this point the solution is already not stable and will give a different pH reading than what is expected.

Calculate change in height of a 2kg ball moving a speed of 10m/s up a frictionless ramp until it stops
Nataliya [291]

The change in the height of the object is 5.1 m.

<h3>Conservation of mechanical energy</h3>

The principle of conservation of mechanical energy states that the total energy of an isolated system is always conserved.

The change in the height of the object is calculated by applying the principle of conservation of mechanical energy as follows;

P.E = K.E

mg \Delta h = \frac{1}{2} mv^2\\\\g \Delta h = \frac{1}{2}v^2\\\\\Delta h = \frac{v^2}{2g} \\\\\Delta h = \frac{(10)^2}{2(9.8)} \\\\\Delta h = 5.1 \ m

Thus, the change in the height of the object is 5.1 m.

What happens when energy is transferred through wave?
vovangra [49]
In electromagnetic waves energy is transferred through vibrations of electric and magnetic fields. In sound waves energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves energy is transferred through the vibration of the water particles.

Hoping this helps.
