Answer:
This can easily be solved using the "range" formula
R = V0^2 * sin 2θ / g
V0^2 = g R / sin 2θ = 9.80 * 43 / sin 144 = 717 m^2/s^2
V0 = 26.8 m/s
B.The shorter a wire is, the higher the resistance will be
Microwaves at the specific frequency where vibrates water molecules
Or
Infrared waves is the other name for heat
Answer: 133.33nm
Explanation: refractive index, n = real depth/apparent depth
Oil thickness= real depth = 200nm
Wavelength from under the water = apparent depth = a
n = real depth/a
1.5 = 200/ a
a = 200/ 1.5
a = 133.33nm
Answer:n contrast, an electromagnetic wave, such as light or radio waves, doesn't need a medium and can travel through empty space. While all electromagnetic waves are transverse, mechanical waves can be transverse or longitudinal, which brings us to our next type of wave.
