Consider any ocean wave, what is the relationship between an ocean wave and the energy of that wave?
A) Wave energy decreases as the wave moves closer to the shore
B) The greater the wavelength, the more kinetic energy the wave has
C) Wave energy is directly proportional to the amplitude of the wave
D) Wave energy increases with frequency and decreases with wavelength
Answer:
C.
Explanation:
Wave energy is directly proportional to the amplitude of the wave. It is a square function.. double the amplitude (wind/solar power picks up) the energy in the ocean wave is quadrupled.
Wave energy is directly proportional to the amplitude of the wave. Therefore, option C is correct.
What is wave energy?Waves of heat, light, sound, and water carry a variety of energies. All types of energy can be converted into work because energy is defined as the capacity to perform work. The movement of an object in the direction of the force acting on it is referred to as work in science. When they move items, waves do really work. This process is evident when sand is carried or large logs are moved across ocean basins.
Work can also be transformed into the acoustic energy produced when waves crash on the coast. The potent force of waves can also be used to move generator components and generate electricity.
A wave's energy content is influenced by its height, wavelength, and breaking point in addition to other factors. When waves of identical wavelengths fall back to sea level, the wave with the greater amplitude will release more energy than the wave with the lesser amplitude. Therefore, option C is correct.

An ice skater weighs 500 [N]. He is coasting to the right at a constant velocity of 2 [m/s]. Assume
the ice is frictionless.
What is the net force on the skater?
Answer:
The net force on the skater is zero. ([tex]F_{net} = 0\,N[/tex])
Explanation:
According to Newton's First Law, an object is at equilibrium when either it is at rest or moves at constant velocity, which means a net force of zero. Based on the given statement, there are no external forces acting on skate and, therefore, the net force on the skater is zero. ([tex]F_{net} = 0\,N[/tex])

16. Evaluate the expression below if
a = -8, b = 17, and c = 21
az - (b + c)
Answer:
(if for solving for z)
z= -4.75
Explanation:
az-(b+c) [set equal to zero]
az-(b+c)=0
+(b+c) +(b+c)
az = (b+c) [now substitute the variables]
-8z = (17+21)
-8z = 38 [divide both sides by -8 to get z alone]
z = -4.75

The support of the State governments in all their rights…I consider one of the essential principles of our Government… How is Jefferson's view reflected in the U.S. Constitution? The U.S. Constitution lists all powers given to the states. The U.S. Constitution gives unlimited power to the states. The U.S. Constitution says powers not given to the federal government belong to the states. The U.S. Constitution gives unlimited power to the federal government and little to the states.
Answer:
The Correct Answer is
The U.S. Constitution says powers not given to the federal government belong to the states.
Explanation:
In the paragraph, Jefferson states defending the rights of states is one of the fundamental, or most significant, policies of our administration. Did that get you to remember the Tenth Amendment? It restrains the authority of the central government, defending the rights of states. It states that the central government only has the authorities listed in the Constitution. Unlisted authorities belong to the states.

A bullet is fired at an angle of 45°. Neglecting air resistance, what is the direction of acceleration during the flight of the bullet?
a) upward
b) downward
c) dependent on the initial velocity
d) at a 45 angle
Answer:
b) downward. Correct choice
Explanation:
Projectile Motion
It's known as the type of motion that experiences an object that is projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
The gravity manifests through the acceleration of gravity g whose value is [tex]9.8 m/s^2[/tex] and points downward. The object will eventually fall to the ground at a time and speed which depends on the initial speed and launch angle.
When the bullet is fired regardless of the initial speed and angle, the only acceleration of the system is g, thus:
b) downward. Correct choice
The acceleration acts on the bullet will be the acceleration due to gravity that is g and has a downward direction.
What will be the direction of the acceleration of Bullet fired?Since the bullet is fired at an angle of 45 so the bullet will travel in a projectile. So every point in time the acceleration due to gravity will act on the bullet.
After some point in time, the bullet will come to the surface of the earth as the energy in the bullet will reduce.
As we know that anything present on the earth is under the influence of the earth's gravity.
So the fired bullet will experience acceleration due to the gravity of the earth and the direction of the acceleration will always be downwards.
So the bullet will eventually fall to the ground at a time and speed which depends on the initial speed and launch angle.
Thus the acceleration acts on the bullet will be the acceleration due to gravity that is g and has a downward direction.

Increasing the amount of current that flows through a wire________ the strength of an electromagnet.
Answer:
increases
Explanation:
edgu2020
Increasing the amount of current that flows through a wire increases the strength of an electromagnet.
What is an electromagnet?An electromagnet is a type of magnet that is created by running an electrical current through a coil of wire. Unlike permanent magnets, which have a fixed magnetic field that cannot be adjusted, the magnetic field of an electromagnet can be turned on and off or adjusted by controlling the amount of current flowing through the coil.
The strength of an electromagnet depends on several factors, including the number of coils in the wire, the amount of current flowing through the wire, and the type of core material used in the coil. Electromagnets are widely used in various applications, such as in electric motors, generators, relays, MRI machines, and particle accelerators.
One of the advantages of electromagnets is that their magnetic field can be easily controlled by adjusting the amount of current flowing through the wire. This makes them useful in applications where the magnetic field needs to be turned on and off, or where a variable magnetic field is required.
Another advantage of electromagnets is that they can be designed to be much stronger than permanent magnets. This is because the strength of an electromagnet is directly proportional to the amount of current flowing through the coil, which can be increased or decreased as needed.
Here in this question,
This happens because an electromagnet is created when an electric current flows through a wire, generating a magnetic field around the wire. The strength of the magnetic field depends on the amount of current flowing through the wire.
When more current flows through the wire, the magnetic field around the wire becomes stronger. This is because the magnetic field is directly proportional to the current flowing through the wire, as well as the number of loops of wire in the coil.
Therefore, increasing the current flowing through a wire in an electromagnet will increase the strength of the magnetic field, resulting in a stronger electromagnet.
