Answer:
O pH is a measure of the concentration of H+ ions in a solution of an acid or base. The pH plots
the concentration of solutions in a range from 0-14.
Explanation:
pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral.
Answer:
10 m/s
Explanation:
Given:
Amplitude of atomic vibrations (λ) = 10⁻⁹ cm = 10⁻⁹ × 10⁻² m = 10⁻¹¹ m [1 cm = 10⁻² m]
Frequency of the vibrations (f) = 10¹² Hz
In order to find the atom's maximum speed, we need to make use of the formula that relates speed, frequency and wavelength of the vibration.
Therefore, the formula for maximum speed is given as:

Now, plug in the values given and solve for speed 'v'. This gives,

Therefore, the atom's maximum speed due to thermal energy provided is 10 m/s.
