To solve the problem we will require the concept of Force as a definition of pressure and Area, and the concept of light pressure itself determined by the relationship between intensity and the speed at which light travels. We will match the terms and find the desired force value,
Here,
P = Pressure
A = Area
Pressure due to the light of the sun will be
Here,
I = Intensity
c = Speed velocity
Equation both therms we have that
We have a circular area then
Replacing with our values (Adding the radius of the Earth)
Therefore the Force on Earth due to radiation pressure is
Answer:
The induced current will flow in a direction north of the plane of the paper
Explanation:
This is in compliance with faraday's right hand rule pictured below.
Answer:
Students should realize that each atom in a group has the same number of electrons in its outermost energy level. For instance, hydrogen, lithium, sodium, and potassium all have 1 electron on their outer energy level. Let students know that these electrons in the outermost energy level are called valence electrons.
Answer: Ionization energy is the amount of energy necessary to <u>remove an electron from an atom</u>
Explanation:
Ionization consists of the production of ions, which are electrically charged atoms or molecules due to the excess or lack of electrons with respect to a neutral atom or molecule.
In this sense, ionization energy is the <u>energy necessary to separate (remove) an electron from a gaseous atom</u>, isolated and in a fundamental state. This is because <u>electrons are strongly attracted to the nucleus and it is necessary to provide energy to separate them</u>. However, where the atom always loses electrons is in the last layer, which is where the weakest electrons are attracted to the nucleus.
Answer:
1.) Liquid
2.) Low
3.) Molecular
4.) Surface tension
5.) Solvent
Explanation:
Water is important to living things because it remains in the LIQUID state over a wide range of temperatures. Water in lakes and oceans does
not experience large temperature changes because liquid water has a
LOW specific heat, so it must absorb or release a lot of energy as its temperature changes. The MOLECULAR forces between water
molecules cause water to form round droplets and cause water's high SURFACE TENSION. Water is also an important SOLVENT because it can
dissolve many different substances.
