Answer:
F=-100N; a=1.3m/s^2
Explanation:
Force is being made by student, so wall counteracts that force by not moving so it is equally opposite.
The arrangement of electric charges produces an electric field while the flow of electric charges is known as current electricity.
<h3>What is an electric field?</h3>
An electric field is a region of space where a charged body produces an electrical force which is felt by another body when brought close to or around that region.
Arrangement of electrical charges produces an electric field.
The flow of charges is known as electricity.
Therefore, the arrangement of electric charges produces an electric field while the flow of electric charges is known as electricity.

The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.
The answer would be: <span>b. interactions between the atmosphere and geosphere during a drought
The experiment is clearly demonstrating what happens in drought. The soil that is put into direct sunlight without getting any water. The heat from the sunlight will be absorbed by the soil, makes the water content of the soil evaporates into the air. Since you don't give any water, the soil will be dry and start to crack.
The soil should represent the geosphere. The air represents the atmosphere.

<span>Answer: 124eV
Explanation: Apply Planck - Einstein Relation to calculate the energy of an X-Ray photon that has a frequency of 3.00 x 10^16 Hz and the energy of a photon is proportional to its frequency
E= hv
where E - the energy of the photon
h - Planck's constant, equal to 6.626 x 10^-34 Js
v - the frequency of the photon
and 1 Hz is equal to 1 s^-1
Thus E= 1.988 x 10^-17J
Now convert the energy of photon from joules to eV
Therefore we get 1.988 x 10^-17J x ( 1 eV / 1.6022 x 10^-19 J)
= 124 eV.</span>
