Answer:
The acceleration is constant and positive
Explanation:
The straight line indicates that the acceleration is constant, while the positive slope indicates that the line is positive.
A Atom is the basic unit of each type of element
Answer:

Explanation:
The intensity of an electromagnetic wave can be expressed in terms of the magnetic field using the next relationship:
(1)
- c is the speed of light (3*10⁸ m/s)
- μ₀ is the permeability of free space (in vacuum ) (1.26*10⁻⁶ N/A²)
- B₀ is the magnetic field


Now, let's define the relationship between power (P) and average intensity (I).

- P is the power
- A is the area crossed
So we can calculate the power.

Finally, energy is the product of P times time, so:
