The wave's speed is 1.25 m/s.
<h3>What is Wavelength?</h3>
The distance over which a periodic wave's form repeats is known as the wavelength in physics. It is a property of both travelling waves and standing waves as well as other spatial wave patterns. It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings.
The spatial frequency is the reciprocal of wavelength. The Greek letter lambda (λ) is frequently used to represent wavelength.
The term wavelength is also occasionally used to refer to modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids.

Explanation:
u = 13m/s
s = 36.2m
a = 9.81m/s² (positive because it is acting on the same direction as the velocity)
Using Kinematics, we have v² = u² + 2as = (13)² + 2(9.81)(36.2) = 879.244m²/s². => v = 29.65m/s.
Answer:
The correct option is
(e)either (c) or (d) could be correct.
Explanation:
The electric field of a charge radiates out in all directions and the intensity of the electric field strength given by E = F/q₀, diminishes as the lines of force moves further away from the source. The direction of F and E is in the line of potential motion of the source charge in the field.
Equipotential surfaces are locations in the radiated electric that have the same field strength or electric potential. The work done in moving within an equipotential surface is zero and as such since
Work = Force × distance = 0 where distance ≠ 0.
The force acting between two points on an equipotential surface is also zero or the component of the force within an equipotential surface is zero and since there is a force in the electric field, it is acting at right angles to the equipotential surface which could be horizontally to the left or right directions where the equipotential surfaces due to the charge distribution are in the vertical plane.
Therefore it is either horizontally to the left, or horizontally to the right.
"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:
340 m/s
Solution:
As per the question;
Time, t = 3.0 s
Total distance moved by the ship, d = 10,500 km
The increase in speed, v = 340 m/s
Now,
To calculate the U.S.S Burger's change in speed, 
:
The final velocity is given by:
(1)
where
Also, the change in velocity is given by:
(2)
Now, from eqn (1) and (2):
