Answer: 0.3m
Explanation:
Given the following :
Speed of radio wave(V) = 3 × 10^8 m/s
If 1M = 10^6
Frequency(F) = 90MHz = 90 × 10^6
Wavelength (λ) =?
Speed of wave (V) = frequency(F) × wavelength(λ)
V = fλ
(3 × 10^8) = (90 × 10^6) × λ
λ = (90 × 10^6) / (3 × 10^8)
λ = 30 × 10^(6 - 8)
λ = 30 × 10^-2
λ = 0.3m
a increase in the velocity by 8ms increase every second the math is you take the base velocity usually 0 but in this case 25 and subtract that by the top velocity which is 49 and then divide by the time of increase which is 3 so your answer is 8ms increase per second
10mph is the acceleration that u are looking for
Answer:
m = 7000 - 500 = 6500 g
ρ = m/v = 6500 gm / 500 cm³ = 1.3 g/cm³
The paint brush floats because its density is less than that of the paint and has displaced its weight in the paint.
