Answer:
0 N
Explanation:
suppose, you push a box with 5 N, and another person pushes the box on the opposite side of the box with 5 N, the net force (resultant ) is 0 N, the box will not move if it wasn't moving
hope this helps
<u>Analysing the Question:</u>
We are given:
initial velocity (u) = 100 m/s
final velocity (v) = <em>v m/s</em>
distance (s) = 125 m
acceleration (a) = 5 m/s²
<u>Solving for Final Velocity (v):</u>
from the third equation of motion:
v² - u² = 2as
v² - (100)² = 2(5)(125)
v² - 10000 = 2500
v² = 2500 + 10000
v² = 12500
v = 111.8 m/s
Answer:
1)
2)
Explanation:
1)
The intensity equation is given by:
Where:
- P is the power of the radio wave
- r is the distance from the source
2)
Now, the intensity and the electric field are related as:
Here:
- c is the speed of light
- ε₀ is the electric permittivity
- E is the electric field
We need to solve it for E.
I hope it helps you!
