<span>Continental crust is less dense than oceanic crust </span>
I believe the correct answer from the choices listed above is option A. Jonah finds a rusty nail outside. The nail is an example of <span>chemical weathering. Rusting of nail is a result of reaction of iron with water in air. Hope this answers the question. Have a nice day.</span>
Period is T = 1/f. The frequency, f, is 5cycles/10s = 0.5. So the period T=1/0.2 = 2.
Answer:
28.79%
Explanation:
Given
Design Speed, V = 120km/h = 33.33m/s
Radius, R = 300m
Side Friction, Fs = 0.09
Gravitational Constant = 9.8m/s²
Using the following formula, we'll solve the required rate of superelevation.
e + Fs = V²/gR where e = rate
e = V²/gR - Fs
e = (33.33)²/(9.8 * 300) - 0.09
e = 0.287853367346938
e = 28.79%
Hence, the required rate of superelevation for the curve is calculated as 28.79%
