Answer:- 0.134 seconds
Solution:- The speed is given as 
and the circumference is 24900 miles which is same as the distance light have to covered. It asks to calculate the time required to cover this distance by the light.
Unit conversion is needed from miles to meters since the speed is given in meters per second.
1 mile = 1609.34 meters
Thus, 
= 40072566 meters
Now, 
Rearranged for time, that gives: 
Inserting the values:
= 0.134 seconds
Hence, light would take 0.134 seconds to traverse the indicated distance. The answer without the unit is 0.134.
Q is determined to be 12.38. The Nernst equation is expressed as Ecell = E°cell - (2.303RT/nF) log Q, where Q represents the reaction quotient. The reaction quotient Q is calculated by taking the product of the products' concentrations divided by the product of the reactants' concentrations. For an electrochemical cell, Q is the concentration ratio of the solution at the anode compared to that at the cathode. Consequently, Q = [anode]/[cathode], specifically Q = 0.052/0.0042, arriving at a value of Q = 12.38.
d is your answer; I hope this assists you.
The issue with your setup is that the surface where you placed the drop is contaminated or dirty, preventing it from being wetted by the solution. To fix this, thoroughly clean the surface before applying the drop.
True; True; False; True; True. Explanation: Organic compounds can exist in pure form, but they are typically found in mixtures, such as in petroleum, which implies that the compound one obtains could be impure. Organic compounds can exist in three states: solid, liquid, or gas. The state depends on the molecular forces and the molar mass involved. For instance, at room temperature, gasoline is a liquid, natural gas is a gas, and glucose is a solid. The fundamental characteristic of organic compounds is that they contain carbon (C) and hydrogen (H), while other elements like oxygen (O), nitrogen (N), halogens, and sulfur (S) may or may not be part of their structure. Because carbon can form chains, millions of organic compounds are known. Spectroscopic methods can provide information such as composition, molar mass, and diffraction patterns, which can assist in identifying certain chemical properties and may require additional identification tests.
