You've listed a lot of data here, in both metric and customary units,
and I'm not even sure it's all needed. Let me try and boil it down:
Pressure on a surface =
(total force on a surface) divided by (area of the surface).
The answer to the question is the pressure expressed in pascals.
There's actually enough information here to answer the question
in 2 different ways. We could ...
-- simply convert (0.03 pound per inch²) to pascals, or
-- go through the whole calculation of force, area, and then their quotient.
To me, converting 0.03 psi to Pa looks easier.
-- 1 pascal = 1 newton / 1 meter²
-- On Earth, 1 kilogram of mass weighs 9.8 Newtons and 2.2 pounds.
From this, we can calculate that
2.2 pounds of force = 9.8 newtons of force.
1 pound = 4.45 newtons
(0.03 pound/inch²) x (4.45 newton/pound) x (1inch/2.54cm)² x (100cm/1m)² =
(0.03 x 4.45 x 1² x 100²) / (2.54² x 1²) newton/meter² = 206.9 Pa .

Answer:
When it is cloudy, many of the sun’s rays never reach the Earth. It leads to cooler temperatures.
Explanation:
During the day, the sun warms the earth. When the sky is clear, more heat reaches the earth's surface . This leads to warmer temperatures.
However, when the sky is cloudy, a few drops of clouds reflect some of the sun's rays. As a result, less solar energy can reach Earth's surface, causing Earth to heat up more slowly. This leads to cooler temperatures.
If cloudy skies are forecast when forecasting daytime temperatures, expect lower temperatures than you would expect if clear skies were forecast.
Similarly, cloud cover at night has the opposite effect. When the sky is clear, the heat emitted from the earth's surface freely escapes into space, resulting in cooler temperatures.
However, when there are clouds, some of the heat from the earth's surface is captured by the clouds and returned to the earth. As a result, temperatures drop more slowly than when the sky is clear.

Answer: magnitude = 5 and angle = 160°
Explanation:
A vector has magnitude 5 and angle -20°
A vector can be written in terms of its components as :
using trigonometry identity:
sin θ = -sin ( 180 + θ )
cos θ = - cos (180 + θ)
Thus, we can write the same vector as:
Magnitude
Thus, the magnitude would be A = 5 and angle = 180+θ= 180-20 = 160°

The described subatomic particle is a neutron, which is electrically neutral and has a mass of approximately 1 atomic mass unit (amu). Neutrons are integral components of atomic nuclei, contributing to nuclear stability and various nuclear processes.
The subatomic particle described is a neutron. Neutrons are one of the fundamental particles that make up the atomic nucleus, along with protons. Neutrons have no electric charge, meaning they are electrically neutral, which is in contrast to positively charged protons and negatively charged electrons.
One of the defining characteristics of neutrons is their mass, which is approximately 1 atomic mass unit (amu). An atomic mass unit is a unit of mass used to express atomic and molecular weights, and it is approximately equal to the mass of a proton or a neutron. More precisely, the mass of a neutron is slightly greater than the mass of a proton, but for most practical purposes, it is considered to be 1 amu.
Neutrons play a crucial role in the stability of atomic nuclei. They help balance the electrostatic repulsion between positively charged protons, holding the nucleus together through the strong nuclear force. Neutrons are involved in various nuclear processes, including nuclear reactions and the production of isotopes in nuclear reactors and particle accelerators.
