λ = 3.125 m
λ = 2.83 m

Given
Frequency of radio : 96 MHz and 106 MHz
Required
The wavelength
Solution
Wavelength : from the crest to the crest of the next wave or the trough to the trough
Frequency (f): number of waves in one second
v = λ x f
λ = v : f
Input the value :
f = 96 MHz = 96 x 10⁶ Hz
λ = v : f
λ = 3 x 10⁸ : 96 x 10⁶
λ = 3.125 m
f = 106 MHz = 106 x 10⁶ Hz
λ = v : f
λ = 3 x 10⁸ : 106 x 10⁶
λ = 2.83 m
D. Humid Subtropical which is like hot subtype locate in climate zone with a 45 degree north to 50 degrees north which mostly in the east to 100th meridian
Answer:
40454.4 N
Explanation:
mass, m = 320 kg
density of hot air, d = 1.19 kg/m^3
density of cold air, d' = 1.29 kg/m^3
Volume of the balloon, V = mass / density
V = 320 / (1.29 - 1.19)
V = 3200 m^3
So, buoyant force
F = Volume x density outside x gravity
F = 3200 x 1.29 x 9.8
F = 40454.4 N
thus, the buoyant force is 40454.4 N.
