Hi there!
We can begin by solving for the time it takes the projectile to reach the ground.
Use the equation:
Plug in the given height:
Use the equation:
d = vt, to solve for the horizontal distance:
d = (54)(8.536) = 460.944 m
Answer:
earth
because it effects climate change
Sodium (Na) is a Alkali metal so that's the answer
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!
