What? im so confused lol. the force is y=mx+b
Answer:
A. negative; virtual.
Explanation:
A concave lens always forms a virtual erect and diminished image. The reason why is that the image is actually formed by the intersection of virtually extended refracted rays.
Hope this helps!
Please mark as brainliest if correct!
Answer:
89.5 Hz
Explanation:
The relationship between the frequency and the wavelength is given by the following formula:

where,
f = frequency
c = speed of light
λ = wavelength
Since the speed of light is constant. Therefore the formula suggests an inverse relationship between the frequency and the wavelength. Hence, the station with the lowest frequency will have the longest wavelength.
Therefore, the answer is:
<u>89.5 Hz</u>
