Answer:
12 m
Explanation:
f = 0.2 Hz, v = 2.4 m/s
v = f x λ
Where, λ is the wavelength
λ = v / f = 2.4 / 0.2 = 12 m
The wavelength is defined as the distance between two consecutive crests or troughs.
So, the distance between two consecutive crests is 12 m.

Answer:
speed = 12.353 m/s
Explanation:
distance = 63 m
time = 5.1 s
substitute the values into the formula
speed = 12.353 m/s
Answer:
11.5 m/s²
Explanation:
The centripetal acceleration, a = rω² where r = radius of cylinder = 10.7 cm = 0.107 m and ω = angular speed = 2πN where N = number of revolutions per second = 1.65 rev/s
So, a = rω²
a = r(2πN)²
a = 4π²rN²
substituting the values of the variables into the equation, we have
a = 4π²rN²
a = 4π²(0.107 m)(1.65 rev/s)²
a = 4π²(0.107 m)(2.7225 rev²/s)²
a = 4π² × 0.2913075 mrev²/s)²
a = 11.5 m/s²
Answer:
More carbon dioxide or greenhouse gases in the atmosphere can lead to global warming. Oceans store a large amount of heat, and increases in sea surface temperature can increases the amount of water vapor over the oceans, and that will increases the amount of greenhouse gases.
