<em>its wave length </em>
<em>its wave lenght because how its measure</em>
The wavelength of the given wave is calculated through the equation,
λ = c/v
where λ is the wavelength,
c is the speed of light, equal to 3x10⁸ m/s, and
v is the frequency
Then, we substitute the known values to the equation,
λ = (3 x 10⁸ m/s)/(1280 x 10³/s)
λ = 234.375 m
The wavelength of the "am" radio station is 234.38 m.
Answer: Distance
I’m not sure if it is correct, but I am pretty sure it is......
I hope this helps :)
Answer:
0.281 m
Explanation:
From vᵧ = uᵧ - gt
where vᵧ = final vertical component of the velocity
uᵧ = vertical component of the initial velocity = 2.5 m/s
g = 9.8 m/s²
At maximum height, vᵧ = 0 m/s
So,
Time to reach maximum height, t = uᵧ/g = 2.5/9.8 = 0.255 s
Total time of flight, T = 2 × time to reach maximum height
T = 2 × t = 2 × 0.255 = 0.510 s
Range of the cannon = uₓ T = 0.55 × 0.510 = 0.281 m
Note uₓ = horizontal component of the initial velocity.
