56
Explanation:
I just want the points to be completely honest with you.
That's false. No medium = no sound.
The atoms furthest from the nucleus
Wildlife researcher starts from a and then reaches b, he turns towards north 40 degree to move towards c.
Total displacement is ac
Total horizontal displacement = 4+4 cos40 =7.06 km
Total vertical displacement = 4 sin40 =2.57 km
Total displacement
= 7.51 km
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:
