Answer: Describe one of the customs that Darwin had to participate in at sea as new sailor.
Explanation: At 26, Darwin had come to the archipelago, which straddles the Equator some 600 ... Darwin's revolutionary theory was that new species arise naturally, by a ... What was supposed to be a 6-hour excursion became a 51-hour nightmare as we ... Darwin, who ventured onto several smaller ones, were like “a sea petrified
D. Pickup truck because it's heavy and it gained more momentum
From the solubility rules, both reactions 1 and 2 lead to precipitates.
<h3>What is a precipitate?</h3>
The term precipitate refers to the solid that separates out of the reaction mixture . We know that the solubility of a substance in water is predicated on the solubility rules.
1) The reaction here is;
Fe(NO3)3(aq) + 3NaOH(aq) ------> Fe(OH)3(s) + 3NaNO3(aq) - The precipitate is Fe(OH)3 because only the hydroxides of group 1 elements are soluble in water.
2) The reaction is;
Pb(NO3)2(aq) + 2KI(aq) ----->PbI2(s) + 2NaNO3(aq) - The precipitate is PbI2 because most iodides are soluble except the iodides of Ag+, Hg+2, and Pb+2
Complete Ionic equation;
Pb^2+(aq) + 2NO3^-(aq) + 2K^+(aq) + 2I^-(aq) ------> PbI2(s) + 2NO3^-(aq) + 2K^+(aq)
Net ionic equation;
Pb^2+(aq) + 2I^-(aq) ------> PbI2(s)

B = magnetic field in the cyclotron = 0.400 T
q = magnitude of charge on a proton = 1.6 x 10⁻¹⁹ C
m = mass of the proton = 1.67 x 10⁻²⁷ kg
f = frequency of revolution of proton in the cyclotron = ?
v = speed of electromagnetic waves = 3 x 10⁸ m/s
λ = wavelength of electromagnetic wave = ?
Frequency of revolution of proton in the cyclotron is given as
f = qB/(2πm)
inserting the values
f = (1.6 x 10⁻¹⁹)(0.400)/(2 (3.14) (1.67 x 10⁻²⁷))
f = 6.1 x 10⁶ Hz
wavelength of electromagnetic wave is given as
λ = v/f
λ = (3 x 10⁸)/(6.1 x 10⁶)
λ = 49.2 m
