Answer:
The energy of the system shall be 8 Joules
Explanation:
In an undamped simple harmonic motion the total energy of the system is conserved which means that the sum of potential and kinetic energies of the system remains constant throughout the motion of the system
In the given problem The total energy of the system at is
This energy shall remain conserved throughout the motion thus when the system is at The total energy of the system shall still be 8 Joules.
The average energy delivered to a surface is 7.5*10^6J.
To find the answer, we have to know about the poynting vector.
<h3>How to find the average energy delivered to a surface?</h3>
- Energy per time through a unit area perpendicular to the direction of propagation of EM wave is called poynting vector.
- We can write the expression of Poynting vector as,
where; E(avg) is the average energy of the EM wave, and c is the speed of light.
- We can rewrite the expression as per our defenition as,
- Thus, the value of average energy will be,
Thus, we can conclude that, the average energy delivered to a surface is 7.5*10^6J.

Answer:
Explanation:
We are asked to find the acceleration of a box.
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The mass of the box is 5 kilograms. There are two forces applied: a 25 Newton force and a 50 Newton force, both applied right. Since they are applied in the same direction, we can add them.
- 25 N right + 50 N right = 75 N right.
Now we know 2 of the variables in the formula:
- F= 75 N or 75 kg*m/s²
- m= 5 kg
Substitute the values into the formula.
We are solving for a, so we must isolate the variable. It is being multiplied by 5 kilograms. The inverse operation of multiplication is division. Divide both sides by 5 kg.
The units of kilograms cancel.
The acceleration is in the same direction as the force, so the acceleration is <u> 15 meters per second squared to the right.</u>
