Answer:
a) 800 km
b) 9.79° & 12.47°
Explanation:
It is known that the wavelength of any material or substance is given by the relation 入 = v/f
From the question, the time between the crest is given as 1.0 h, therefore, t = 1.0 h
Also, remember that frequency, f can be represented by
f = 1/t, and thus,
f = 1/1.0 h = 1.0 h^-1. This is our frequency, and would be used in the primary stated formula
入 = v/f, from the question, the speed is already stated as 800 km/h, so we apply directly
入 = 800 / 1
入 = 800 km. Therefore, the wavelength of the tsunami is 800 km
B,
the smallest angle between the Southern tip of Africa is
Sinθ = 800 / 4500
Sinθ = 0.17
θ = Sin^-1 0.17
θ = 9.79°
The smallest angle between the Southern end of Australia is
Sinθ = 800 / 3700
Sinθ = 0.216
θ = Sin^-1 0.216
θ = 12.47°
Its C. Decreasing its mass
Protein molecule are made from amino acid
Answer:
Kindly check explanation
Explanation:
Given the following :
Vertical component has Magnitude = 20m/s
Angle made with the horizontal (θ) = 25°
Vy = Vsinθ = 20sin25
Vy = 20 × 0.4226182 = 8.4523652 m/s
Horizontal component :
Vx = Vcosθ = 20 × cos25
Vx = 20 × 0.9063077 = 18.126155 m/s
Hence, magnitude :
V = sqrt(Vx² + Vy²)
V = sqrt(8.4523652² + 18.126155²)
V = sqrt (399.99999)
V = 20m/s
