which of these is a rough approximation of the cogito?
Given the Latin meaning of the cogito, we can confirm that it is roughly translated and summarized by the phrase "I think, therefore I am".
Cogito, ergo sum or "The Cogito" is an extremely popular, well-known philosophical phrase credited to Rene Descartes. This Latin phrase is roughly translated as "I think, therefore I am", which appeared originally in "The Principles of Philosophy", and was later translated to a variety of languages in an attempt to reach a wider public, most notably into Latin.

Why cathode rays have reducing effect
Answer:
Cathode rays consist mainly of electrons, they ionize substance, this leads to reduction. Any ions produced are collect by an ion trap in the tube therefore anything the beam of electrons hits is going to gain electrons.

More than 7,000 islands in the Philippines lack access to electricity, so after the sun goes down, light usually comes through kerosene lamps. While cheap, these fire hazards are bad for the environment and human health.
You are an entrepreneur and would like to suggest to the government of the Philippines a better solution to this problem. But to come up with the solution to this problem, you must first understand the nature of chemical bonding and factors that control the structure of compounds. You will study and understand natural materials behavior to build a very cheap and environmentally friendly lamp.
What material do you think can be a cheaper and better alternative to kerosene?
Question 2 options:
There is no better alternative to kerosene.
A material that contains ions, so it can conduct electricity.
A material that contains gas, as gases can conduct electricity.
A material having covalent boding.
Answer:
Question 1: What material do you think can be a cheaper and better alternative to kerosene?
Answer: Generic lamp oil can be used to replace kerosene in lamps. The cheaper lamp oil burns cleaner and has less odor than the more expensive kerosene.

A fusion reaction always creates which of the following?
a A massive amount of energy.
b A massive amount of heat.
C A more massive atomic nucleus.
d A massive number of smaller nuclei.
A fusion reaction can be regarded as the type of reaction that occurs where two lighter elements come together in a type of reaction giving rise to a heavier/more massive element.
A fusion reaction always creates a more massive atomic nucleus (option c).
When the two lighter nuclei comes together in a reaction, a more heavier/massive nucleus is formed but its mass will still be less than the combined mass of the two reactant nuclei.
This also indicates that the left over mass may have been released as energy.

Explanation:
A 250. mL sample of oxygen is collected over water at 25 °C and 760.0 torr pressure. What is the partial pressure
of the oxygen? (Vapor pressure of water at 25°C is 23.8 mm Hg)
Answer:The mass of oxygen gas sample collected over water is 0.544 g.
The given parameters;
temperature of the oxygen gas, t = 25 °C
total pressure of the gas, P = 644 torr
volume of the gas, V = 500 mL
vapor pressure = 23.8 torr
molar mass of oxygen gas = 32 g/mol
The number of moles of the gas collected is calculated by using ideal gas equation as follows;
PV = nRT
where;
R is the ideal gas constant = 62.36 L.torr/mol.K
P is the pressure of the gas = 644 torr - 23.8 torr = 620.2 torr
T is the temperature of the gas = 25 + 273 = 298 K
V is the volume of the gas = 500 mL = 0.5 L
The number of moles of the gas is calculated as follows;
The mass of oxygen gas collected is calculated as follows;
m = 0.017 (32 g/mol)
m = 0.544 g
Thus, the mass of oxygen gas sample collected over water is 0.544 g.
Explanation:
The partial pressure of oxygen is; 760.0 torr - 23.8 torr = 736.2 torr.
What is partial pressure?We know that in a mixture of gases, the pressure that is exerted by each gas is called the partial pressure of the mixture.
In this case, we have the total pressure of the mixture as 760.0 torr and the vapor pressure of water as 23.8 mm Hg or 23.8 torr) at that temperature. Hence, the partial pressure of oxygen is; 760.0 torr - 23.8 torr = 736.2 torr.
