Does the moon control the waves in the ocean?
Answers
Answer:
no don't think so
Explanation:
JESUS CHRIST controls everything 100IQ
No, the moon does not directly control the waves in the ocean. The primary factors that influence the formation of waves in the ocean are wind and the interaction between wind and the water's surface.
The moon, however, does play a significant role in influencing the tides, which are the periodic rise and fall of the ocean's surface.
The gravitational force exerted by the moon, as well as the sun to a lesser extent, creates tidal bulges on the Earth. As the Earth rotates, these tidal bulges move around the planet, resulting in the daily cycle of high tides and low tides.
The gravitational pull of the moon is stronger on the side of the Earth facing the moon, causing a high tide, while on the opposite side, a high tide also occurs due to the centrifugal force resulting from the Earth's rotation. The areas in between experience low tides.
While tides can affect the height and intensity of ocean waves near the coastlines, the actual formation and behavior of waves are primarily driven by wind patterns, water depth, and other factors such as underwater topography.
Waves are generated when the wind transfers its energy to the water's surface, creating oscillations that propagate as waves. These waves can travel vast distances across the ocean, even in the absence of tidal influences.
In conclusion, while the moon's gravitational pull influences the tides, it does not directly control or generate the waves in the ocean.
Waves are primarily driven by wind and other factors, whereas tides are the result of gravitational forces acting on the Earth's oceans.

there are 2 speed cameras,one in area where the speed limit is 30km/h,and another in area where the speed limit is 50km/h,IN WHICH ONE WILL THERE BE A SMALLER TIME INTERVAL BETWEEN THE PHOTOGRAPHS,explain your answer.
(help)
Answers
Answer:
Where speed limit of speed camera is 50 km/h.
Explanation:
Speed cameras work on the principal that photos reflected from the moving car have a higher or lower frequency. This is the Doppler principal. In a car traveling at the speed of light, the waves/particles will not be able to catch up with that car thus no photon will reflect back to the receiver/speed camera thus no speed will be record. Such a speed is impossible to achieve due to the amount of infinite energy expenditure required. This means if the speed is higher and approaching that of light, the frequency of reflected photons will be very high causing high amounts of energy that could damage the speed camera and cause detection. When the car travels at a higher speed, the photos frequency is high thus more energy they will carry and high chances of the vehicle being detected. This means the time interval of photos taken will be smaller.
When the velocity increases does the kinetic energy increase or decrease ?
Answers
Because the mass is constant, if the velocity is increased, the kinetic energy must also increase.
What is the relationship between mass and kinetic energy?
Answers
Answer:
Direct relation
Explanation:
When an object of mass m is moving with some velocity v, it will have kinetic energy. It is possessed by an object whenever an object is in motion. It can be given by the below formula.
[tex]E_k=\dfrac{1}{2}mv^2[/tex]
It is very clear that the kinetic energy of an object is directly proportional to its mass. When the mass increases, its kinetic energy increases directly.

Say you throw a ball straight up into the air and catch it again. The ball reaches a height of 5 m up from your hand before it falls back down and you catch it. The ball is in flight for 2 seconds of time. Determine the ball’s... average velocity average speed
Answers
Explanation:
Given that the heigth up is 5m
then the
distance up = 5m
distance down= 5m
time taken up= 1sec
time taken down= 1sec
average speed= (5+5)/1+1= 10/2= 5m/s
hence the speed up = 5m/s
speed down = 5m/s
average voelocity= 5+5/2 = 10/2= 5m/s

Electronegativity affects the strength of intermolecular forces. A very electronegative atom will create a stronger negative charge . True or false
Answers
Answer:
Electronegative atom will create a stronger negative charge is true.
Explanation:
Given that,
Electronegativity affects the strength of intermolecular forces.
We know that,
Electronegativity :
Electronegativity is a ability of an atom, shared electron to itself.
In periodic table,
When we move left to right in period then the electronegativity increases.
When we move up to down in a group then the electronegativity decreases.
We know that,
The intermolecular forces are dipole-dipole interactions which is the strongest intermolecular force of attraction.
If the electronegativity of atom is more, then the atom gain negative charge.
When the attraction force is more in atoms then the electronegative will be more.
Hence, Electronegative atom will create a stronger negative charge is true.

Kind of energy that an object has due to its motion.
Answers
Answer:
The energy an object has due to its motion is called kinetic energy
Explanation:
Factors Affecting Kinetic Energy: the kinetic energy of an object depends on both its speed and its mass.
Answer:
kinetic energy
Explanation:
In physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.
