Answer:
λ₁ = 2.50 10⁻² m, λ₂ = 1.66 10⁻² m
Explanation:
Microwave communication is very efficient because it does not have atmospheric interference, for which it is widely used and has been regulated to avoid interference, the ku band is in the range between 12 and 18 GHz.
Let's calculate the wavelength for the two extreme frequencies of this band
wavelength and frequency are related
c = λ f
λ = c / f
f₁ = 12 GHz = 12 10⁹ Hz
λ₁ = 3 10⁸ /12 10⁹
λ₁ = 2.50 10⁻² m
f₂ = 18 GHz = 18 10⁹ Hz
λ₂ = 3 10⁸ /18 10⁹
λ₂ = 1.66 10⁻² m
Unfortunately in your exercise the specific frequency is not fired, for significant figures they must be the same number as the figures of the frequency, in general the frequency has 3 or 4 significant figures
Answer:
0. 153m
Explanation:
displacement= velocity/ time
S = 2.3 m/s / 15s
S = 0. 153m
Object will only form shadow if it won't reflect light.
That is, stone will form shadow as it reflects light.
Hope this helps you.
Answer:
d = .076 m
Explanation:
The time for frog A can be calculated from equation of motion
where v_f is final velocity, a is acceleration due to gravity
so from given data we have
t = 0.112 sec
Now we will use that time for frog B
(Note its positive)
For the displacement
d = .076 m
Answer:
A
Explanation:
Because of the convectional currents
