"Erosion will increase, carrying more sand away than before" will most likely result.
Option A
<u>Explanation:</u>
Erosion occurs when the sea area is consumed. There are five main mechanisms that cause coastal erosion. There is corrasion, hydraulic performance, abrasion, oxidation and solution/ corrosion.
Corrasion occurs when the waves remove dirt from the floor (like pebbles) and rotate it at the bottom of the rock. The shoreline is usually longer. Softer areas are covered with sediment from hard areas and rocks are removed.
Answer:
velocity of the metal cylinder = 0.343 m/s
Explanation:
Force putting the metal cylinder is given by
F = mv²/r
But this force will balance the frictional force between the metal cylinder and the turntable
The frictional force is given by
μN = μ × mg = 0.08 × 0.2 × 9.81 = 0.15696 N
r = 0.15 m, m = 0.2 kg,
F = mv²/r = 0.2 v²/(0.15) = 1.3333 v²
1.3333 v² = 0.15696
v² = 0.117
v = 0.343 m/s
Answer:
12353 V m⁻¹ = 12.4 kV m⁻¹
Explanation:
Electric field between the plates of the parallel plate capacitor depends on the potential difference across the plates and their distance of separation.Potential difference across the plates V over the distance between the plates gives the electric field between the plates. Potential difference is the amount of work done per unit charge and is given here as 21 V. Electric field is the voltage over distance.
E = V ÷ d = 21 ÷ 0.0017 = 12353 V m⁻¹
