2) 5m
3) 500m
3) 5,000,000m
An electromagnetic am band radio wave could have a wavelength of 500m, i.e., 500 meters(Option 3).
A wavelength is a disturbance that travels into space with a given frequency and amplitude.
In conclusion, an electromagnetic am band radio wave could have a wavelength of 500m (Option 3).

Answer:
The answer is 12.5 m/s
v=the square root of 2 x(gh)
or v = the square root of 2 x (9.8 x 8)
Explanation:
Answer:
Therefore the horizontal range = 294897.96 m.
Explanation:
Range of a projectile: The range is defined as the horizontal distance from the point of projection to the point where the projectile hit the projection plane again. The S.I unit of range is Meter (m).
It can be expressed mathematically as
R = u²sin2∅/g............................. Equation 1
Where R = Horizontal range, ∅ = angle of projection, u = initial velocity, g = acceleration due to gravity.
Given: u = 1700 m/s, ∅ = 55°,
Constant: g = 9.8 m/s²
Substituting these values into equation 1
R = (1700²sin55)/9.8
R = 2890000/9.8
R = 294897.96 m.
Therefore the horizontal range = 294897.96 m.
