Answer:
6.94 × 10^33Hz
Explanation:
E = hf
Where;
E = Energy of wave (J)
h = Planck's constant (6.626 × 10^-34J/s)
f = frequency (Hz)
According to the information provided in this question, the hypothetical energy of the wave is 4.6J
Hence, using E = hf
4.6 = 6.626 × 10^-34 × f
f = 4.6 / 6.626 × 10^-34
f = 0.694 × 10^34
f = 6.94 × 10^33Hz
na look it up please im not that smart
The Coriolis force is an inertial force that acts on objects that are in motion relative to a rotation reference frame. This causes moving objects to the right ( with respect to the direction of travel ) in the Northern hemisphere and to the left in the Southern hemisphere. The horizontal deflection is zero at the equator. It also causes the surface ocean currents in the Northern hemisphere to deflect to the right and the currents in the Southern hemisphere to deflect to the left.
Answer: the Coriolis force.

Hey There!
At neutralisation moles of H⁺ from HCl = moles of OH⁻ from Ca(OH)2 so :
0.204 * 42.8 / 1000 => 0.0087312 moles
Moles of Ca(OH)2 :
2 HCl + Ca(OH)2 = CaCl2 + 2 H2O
0.0087312 / 2 => 0.0043656 moles ( since each Ca(OH)2 ives 2 OH⁻ ions )
Therefore:
Molar mass Ca(OH)2 = 74.1 g/mol
mass = moles of Ca(OH)2 * molar mass
mass = 0.0043656 * 74.1
mass = 0.32 g of Ca(OH)2
Hope that helps!
