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.

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.

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

Hi there!

If we sum the forces acting on the bucket:

∑F = T (upward) - Mg (downward)

Thus:

ma = T - mg

We can rearrange for T:

ma + mg = T

Plug in the given values:

4.6(3 + 9.8) = T = 58.88 N

Answer:

Falling objects form an interesting class of motion problems. For example, we can estimate the depth of a vertical mine shaft by dropping a rock into it and listening for the rock to hit the bottom. By applying the kinematics developed so far to falling objects, we can examine some interesting situations and learn much about gravity in the process.

The most remarkable and unexpected fact about falling objects is that, if air resistance and friction are negligible, then in a given location all objects fall toward the center of Earth with the same constant acceleration, independent of their mass. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavy ones.

In the real world, air resistance can cause a lighter object to fall slower than a heavier object of the same size. A tennis ball will reach the ground after a hard baseball is dropped at the same time. (It might be difficult to observe the difference if the height is not large.) Air resistance opposes the motion of an object through the air, while friction between objects, such as between clothes and a laundry chute or between a stone and a pool into which it is dropped, also opposes motion between them. For the ideal situations of these first few chapters, an object falling without air resistance or friction is defined to be in free-fall.

Answer:

The electric and magnetic fields are oriented such that they are perpendicular to one another and parallel to the direction of wave propagation.

In an electromagnetic wave, the electric field and magnetic field are oriented such that they are perpendicular to each other and perpendicular to the direction of propagation.

Electromagnetic radiations are made of electromagnetic waves that are produced when an electric field and magnetic field come in contact with each other. Electromagnetic waves are oscillating electric and magnetic fields.

An electric field is generated by a charged particle and a force is exerted by it on other charged particles. Positive charges are accelerated in the direction of the field and negative charges are accelerated in the opposite direction of the field.

The Magnetic field is generated by a moving charged particle and force is exerted by it on other moving particles. The force is always perpendicular to the direction of their velocity.

The electric field and magnetic fields of EM waves are perpendicular to each other and are also perpendicular to the direction of propagation of waves.

Answer:

Explanation:

A car's kinetic energy changes with the speed.  Cars going slower have less potential energy than cars going faster.

The magnitude of the acceleration of the descending block is equal to 1.96 m/s².

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
