Does the moon control the waves in the ocean?
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.

What is the relationship between mass and kinetic energy?
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.

Kind of energy that an object has due to its motion.
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.

Answer:
The resistance in the circuit is 12 ohm.
(D) is correct option
Explanation:
Given that,
Current = 0.25 A
Voltage = 3 V
We need to calculate the resistance
Using ohm's law
[tex]V=IR[/tex]
[tex]R=\dfrac{V}{I}[/tex]
Where, V = voltage
I = current
R = resistance
Put the value into the formula
[tex]R =\dfrac{3}{0.25}[/tex]
[tex]R=12\ ohm[/tex]
Hence, The resistance in the circuit is 12 ohm.

Which particle (proton, neutron, or electron) has a positive charge?
A cyclist, while overtaking another bike, increases his speed uniformly from 4.2 mis to 6.3 m/s over a time interval of 5.3 s. How far does the cyclist
travel while overtaling?
Answer:
27.82m
Explanation:
The distance of the cyclist can be calculated using the formula:
S = ut + 1/2 (at^2)
Where; S = distance
u = initial velocity
a = acceleration
t = time
However, to find acceleration, we use:
a = v - u/t, where v is the final velocity
According to this question, u = 4.2m/s, v = 6.3m/s, t = 5.3s
a = 6.3 - 4.2 / 5.3
a = 2.1/5.3
a = 0.396m/s^2
Hence, using S = ut + 1/2 (at^2)
S = (4.2 × 5.3) + 1/2 (0.396 × 5.3 × 5.3)
S = 22.26 + 5.56
S = 27.82
Therefore, the cyclist travel in 27.82m

A penny is dropped from a building window. If it takes 1.1 s for it
to hit the ground, how high up is the window?
a 150 m
b 2 m
C 16 m
d 6 m
Answer:6m
Explanation:
I guessed the answer and it was right. It was not the tall ones like 16 or 150 because it only took 1.1 second
Given that,
A penny takes 1.1 seconds to hit the ground.
To find,
How high up is the window?
Solution,
When the penny is dropped, its initial velocity is equal to 0 i.e.[tex]u=0[/tex]. The second equation of motion is used to find the relation between position and time. The second equation of motion is :
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Where
s is the distance
a is acceleration
Here, s = the height of the window from the ground and a = g i.e. acceleration due to gravity
So,
[tex]s=\dfrac{1}{2}gt^2[/tex]
Put all the values,
[tex]s=\dfrac{1}{2}\times 9.8\times (1.1)^2\\\\s=6.05\ m[/tex]
or
[tex]s=6\ m[/tex]

Which newton's law would best go with doing push ups?
Answer:
Newton's Third Law
Explanation:
According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
