describe a situation that demonstrates that water waved carry energy
The energy possessed by the water waves in ocean will be due to the gravitation of the moon and the sun.
What is wave energy?Wave energy is a form of renewable energy that can be harnessed from the motion of the waves. There are several methods of harnessing wave energy that involve placing electricity generators on the surface of the ocean.
Due to the gravitation of moon tides, winds, and weather, waves can vary in size and strength. As waves roll through the ocean, they create kinetic energy, or movement.
This movement can be used to power turbines, which, in turn, create energy that can be converted into electricity and power. There are also several ways of harnessing wave energy that utilize the up and down motion of the waves to power pistons/turn generators.
Hence the energy possessed by the water waves in ocean will be due to the gravitation of the moon and the sun.

Compared to oceanic crust , continental crust is generally
Continental crust is typically thicker, more complex in its composition and predominantly made of granite compared to oceanic crust which is thinner, simpler and mainly composed of basalt. The continental crust covers 45% of earth's surface, whereas oceanic crust covers 55%. The continental crust, being thicker and more buoyant, is generally not subducted in plate tectonics unlike the oceanic crust.
Explanation:Compared to the oceanic crust, the continental crust is typically thicker and composed predominantly of different types of rocks. While oceanic crust is about 6 kilometers thick and made primarily of basalt, continental crust varies between 20 to 70 kilometers in thickness and is primarily composed of a volcanic class of silicates called granite.
Notably, the crust is the easiest layer for geologists to study and makes up only about 0.3% of the total mass of Earth. The continental crust covers about 45% of the surface, some of which lies beneath the oceans. The typical density of the crust, both oceanic and continental, is around 3 g/cm³.
The continental crust tends to be older and more complex than the oceanic crust. It consists of many different types of rocks formed over billions of years from many different types of processes. Due to the increased thickness and complexity of its composition, the continental crust is more buoyant than the oceanic crust and hence is not subducted during the process of plate tectonics. Oceanic crust, being thinner and denser often gets subducted beneath the continental crust at convergent boundaries.

what is transferred by a radio wave
A radio wave transfers energy and information through space via oscillating electric and magnetic fields.
A radio wave is a type of electromagnetic radiation that transfers energy through space. When a radio transmitter generates a signal, it creates a rapidly oscillating electric field, which in turn creates a magnetic field that propagates through the surrounding space at the speed of light.
This changing magnetic field induces a corresponding electric field in any conductive material (such as an antenna) that intercepts the wave. The electrical energy carried by the radio wave is then transformed into an electrical current that can be amplified and processed by electronic circuits.
In practical terms, radio waves are used to transmit various types of information, including voice and music for broadcasting, data for wireless communication, and navigation signals for GPS. The specific type of information transmitted by a radio wave is encoded in its frequency, amplitude, and modulation, which determine the characteristics of the wave and allow it to be decoded by the receiver.
Therefore, Through the use of oscillating electric and magnetic forces, radio waves transmit information and energy through space.

Assuming no air resistance, all projectiles have:
Explanation:
The motion of an object that move only under the action of gravity is called projectile motion.
All projectile have only acceleration due to gravity. In projectile motion, the horizontal movement of an object equals zero.
Equation of motion for a projectile are :
In horizontal motion,
Acceleration = [tex]a_x=0[/tex]
Velocity- time = [tex]v_x=v_{0x}[/tex]
Displacement - time, [tex]x=x_0+v_{0x}t[/tex]
In vertical motion,
Acceleration = [tex]a_y=-g[/tex]
Velocity- time = [tex]v_y=v_{0y}-gt[/tex]
Displacement - time, [tex]y=y_0+v_{0y}t-\dfrac{1}{2}gt^2[/tex]
Hence, this is the required solution.
When there is no air resistance, all projectiles accelerate in a vertical downward direction, which is equal to the acceleration due to gravity.
When an item is launched into the air, its motion is called a projectile motion when there is negligible air resistance and just gravity acting on it after the initial force that propels it into the air. A projectile is what it is, and its trajectory is what it took to get there.
The most important concept in projectile motion is that horizontal and vertical movements are independent of one another when air resistance is disregarded.

which would ultimately cause the armature in an electric motor to spin?
In an electric motor, the armature spins due to the interaction between the magnetic field produced by the stator (the stationary part of the motor) and the magnetic field produced by the armature itself.
Here's a simplified explanation of the process:
Supplying Power: When electric current flows through the motor's coils (which are part of the armature), it creates a magnetic field around the coils. This process usually involves a commutator and brushes to direct the current flow in the coils effectively.
Magnetic Fields: The stator also has its own set of coils that are arranged in such a way that when current passes through them, they create a magnetic field. This magnetic field interacts with the magnetic field produced by the armature.
Electromagnetic Force: Due to the interaction of these magnetic fields, an electromagnetic force is generated. This force causes the armature (which contains the coils) to rotate. The direction of rotation depends on the direction of the current and the orientation of the magnetic fields.
Continuous Rotation: As long as the electric current is supplied to the motor, this process continues, resulting in continuous rotation of the armature.
In summary, it's the interaction of magnetic fields generated by the armature and the stator, along with the flow of electric current, that causes the armature to spin in an electric motor.
