for hundreds of years scientists deny the existence of rogue waves until the presence of when was finally caught on record. when and where was the first time a rogue wave was measured?
Answer:
A rogue wave estimated at 18.3 meters (60 feet) in the Gulf Stream off of Charleston, South Carolina. At the time, surface winds were light at 15 knots.
Explanation:
Rogue, freak, or killer waves have been part of marine folklore for centuries, but have only been accepted as real by scientists over the past few decades.
Rogues, called 'extreme storm waves' by scientists, are those waves which are greater than twice the size of surrounding waves, are very unpredictable, and often come unexpectedly from directions other than prevailing wind and waves.
Most reports of extreme storm waves say they look like "walls of water." They are often steep-sided with unusually deep troughs.
Since these waves are uncommon, measurements and analysis of this phenomenon is extremely rare. Exactly how and when rogue waves form is still under investigation, but there are several known causes:
Constructive interference. Extreme waves often form because swells, while traveling across the ocean, do so at different speeds and directions. As these swells pass through one another, their crests, troughs, and lengths sometimes coincide and reinforce each other. This process can form unusually large, towering waves that quickly disappear. If the swells are travelling in the same direction, these mountainous waves may last for several minutes before subsiding.
Focusing of wave energy. When waves formed by a storm develop in a water current against the normal wave direction, an interaction can take place which results in a shortening of the wave frequency. This can cause the waves to dynamically join together, forming very big 'rogue' waves. The currents where these are sometimes seen are the Gulf Stream and Agulhas current. Extreme waves developed in this fashion tend to be longer lived.
Hope this helps, have a nice day/night! :D
On January 1st, 1995, the first accurate measurement of a rogue wave took place. It was captured by a laser detector on Statoil's Draupner oil drilling rig, which is situated 100 miles off the Norwegian coast.
What is rogue wave?
Although rogue, freak, or killer waves have been mentioned in maritime legend for many years, scientists have only recently acknowledged their existence.
Scientists refer to these waves as "rogues," or "severe storm waves," since they are more than twice as large as the waves around them, very unpredictable, and frequently arrive from directions other than the prevailing wind and waves.
Extreme storm waves are typically described as looking like "walls of water" in reports. Frequently, they have steep sides and exceptionally deep valleys.
Measurements and analyses of this phenomenon are extremely rare because these waves are not common.

A 0. 45 kg soccer ball changes its velocity by 20. 0 m/s due to a force applied to it in 0. 10 seconds. What force was necessary for this change in velocity? N.
Hi there!
We can begin by calculating the impulse exerted on the soccer ball:
I = Δp = mΔv
Plug in the given values:
I = 0.45 × 20 = 9 Ns
I = Ft, so:
I/t = F
9/0.1 = 90 N
A runner slows down after completing a race. Her deceleration is 0.25 m/s2. After 5 s she is travelling at 4 m/s, determine her initial velocity.
Please find attached photograph for your answer.
Hope it helps.
Do comment if you have any query.
The initial velocity of the runner is 5.25 m/s.
What is deceleration?
You've probably seen that when there's a lot of traffic and there are more bikes blocking us, we tend to slow down the speed of our bikes.
Therefore, deceleration is defined as a reduction in speed as the body moves away from the beginning location. The opposite of acceleration is deceleration.
Given parameters:
Deceleration of the runner: a = 0.25 m/s².
Time interval: t = 5 second.
Final velocity: v = 4 m/s.
We have to find initial velocity of the runner: u = ?
From definition of deceleration, it can be written that:
deceleration = (initial velocity - final velocity) time interval
0.25 = (u -4)/5
u = 5.25 m/s.
Hence, initial velocity of the runner is 5.25 m/s.

A crane accelerates a 175 kg load is upward. The tension in the cable is 2000 N. Find the magnitude and direction of the elevator's acceleration.
Hi there!
We can begin by summing forces acting on the load:
∑F = T - Mg (where g ≈10 m/s²)
ma = T - Mg
We can plug in the given values to solve:
ma = 2000 - 175(10)
175a = 250
a = 250/175 = 1.43 m/s² UPWARDS
Answer:
a = 1.63 m/s^2
Explanation:
m = 176kg
Ft = 2000N
2000 = 175 (9.8) +175(a)
2000 = 1715 +175a
-1715 -1715
285 = 175a
175 175
a = 1.63m/s^2

According to the table, what was the hiker's average speed for
the entire hike?
A: 2.0 km/h B: 5.7 km/h C: 6.7 km/h D: 10 km/h
Answer:
6.7 km/h (C)
Explanation:
According to the table, the hiker's average speed for the entire hike would be 6.7 kilometers/hour.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.
The total distance traveled by the hiker = 4 kilometers + 6 kilometers + 4 kilometers west + 6 kilometers north
= 20 kilometers
The total time is taken by the hiker = 45 min + 60 min + 30 min+ 45 min
= 180 min
=3 hours
The average speed of the hiker = 20 kilometers / 3 hours
= 6.7 kilometers / hours
Thus, the hiker's average speed for the entire hike would be 6.7 kilometers/hour.

- A block of mass 4m can move without friction on a horizontal table. This block is attached to another block of
mass m by a string that passes over a frictionless pulley. If the masses of the string and the pulley are negligible,
what is the magnitude of the acceleration of the descending block?
The magnitude of the acceleration of the descending block is equal to 1.96 m/s².
What is the tension in the string?Tension can be described as a force acting along the length of a rope or a cable, especially a force that comprises by a flexible medium. Tension can be described as an action-reaction pair of forces acting at each end of the length of the medium. Each endpoint carried tension and force from the weight attached.
Given that the block with mass, M₁ = 4m is placed on the horizontal table.
The block with mass, M₂ = m is attached by a string.
The block (M₂) suspended by the string experiences tension (T) in the upward direction and weight in the downward direction.
M₂g - T = M₂a ..............(1)
The block (M₁) placed on the table experienced only one force which is tension (T)
T = M₁ a .....................(2)
From equation (1) and (2):
M₂g - M₁a = M₂a
M₁a + M₂a = M₂g
(M₁ + M₂) a = M₂g
a = M₂g/(M₁ + M₂)
Substitute the value of masses of the blocks:
a = m g /( 4m + m)
a = g/5
a = 1.96 m/s²

Hi there!
We can begin by finding the final VERTICAL velocity of the ball.
Use the following kinematic equation: vf² = vi² + 2ad
The ball does not have any initial velocity in the vertical direction so:
vf² = 2ad
Plug in given values:
vf² = 2(9.81)(44) = 29.38 m/s
Find the TOTAL speed using the pythagorean theorem (involving both the horizontal velocity which remains the same and vertical velocity)
v = √(21²) + (29.38²) = 36.115 m/s

A4 m high tank filled with water is drilled with four identical small holes at 1 m, 1.5 m, 2 m and 2.5 m from the bottom of tank, the speed of efflux will be greatest from the hole at?
Answer:
at 2.5m
Explanation:
because 2.5m*4m is 10.0=10
To solve this, we must know each and every concept related to speed of efflux and its calculations. Therefore, hole at 3m will have the greatest speed of efflux.
What is speed of efflux?The velocity of outflow is the speed with which a liquid emerges from a hole cut at a certain height from bottom of the container within which the liquid is contained.
Mathematically, the formula for speed of efflux can be given as
speed of efflux =√2×g×h
g= acceleration due to gravity
h1=4- 1 =3m
h2=4-2=2m
h3=4-2.5=1.5m
h4=4-1.5=2.5
Since speed of efflux is directly proportional to height. More the vale of h more will be speed of efflux. So on calculations, hole at 3m will have the greatest speed of efflux.
Therefore, hole at 3m will have the greatest speed of efflux.
