Answer:
The other person who answered is incorrect- the real answer is light.
Explanation:
A mechanical wave is a wave that requires a medium. A medium is any substance that has a defined set of physical properties and can transmit energy. A medium can be a solid, liquid, or gas. Some examples of a medium include an iron bar, the ground, water, lava, air, and helium in a balloon.
The answer is not sound because sound travels through waves through the air. If you were to put a source of sound in a container that contains no air, you would not be able to hear the sound through the container. Since sound has a wave and a medium, it is a mechanical wave.
The answer is not waves in the ocean because, obviously, this is a wave. Its medium is the water. Since it has a wave and a medium, it is a mechanical wave.
The answer is not waves in a wheat field because, again, this is a wave. The medium is the air. Since it has a wave and a medium, it is a mechanical wave.
The answer is light. Light travels through electromagnetic waves. However, it does not require a medium. Light can travel not only through air and solid materials, but also through the vacuum of space. Since light does not require a medium, it is not a mechanical wave.
I hope this helps !! :)
ocean waves because its not artificial
b. Gravitational and magnetic forces are the most alike because they are both types of charges that occur in nature.
c. Nuclear and magnetic forces are the most alike because they are both related to mass and weight.
d. Strong nuclear force is most like electric because they are both related to distance.
Answer:
d) strong nuclear force is most like electric because they are both realted to distance.

btw good luck with 01.08 Motion Module Exam for Physical Science.
B. increasing the speed of electrons that are flowing
C. creating a potential difference so electrons can flow
The correct choice is
C. creating a potential difference so electrons can flow.
An electron moves from low potential to high potential. so it moves only when there is difference in potential between two locations. A source of voltage creates a potential difference for the electron to move. So the correct choice is C.

Explanation:
b) of less than 600 N is the truck is slowing down
c) equal to 600 N only if the truck is moving at constant velocity
d) equal to 600 N no matter what the acceleration of the truck
e) greater than 600 N if the truck is accelerating
A transport truck pulls on a trailer with a force of 600N [E]. The trailer pulls on the transport truck with a force equal to 600 N no matter what the acceleration of the truck. Option c is correct.
According to Newton's third law of motion, every action has an equal and opposite reaction. As well as the action and reaction are always acted in pairs.
Based on the law of action-reaction,
A transport truck pulls on a trailer with a force of 600N [E]. The trailer pulls on the transport truck with a force greater than 600 N if the truck is accelerating.
If the truck is moving at constant velocity the acceleration is zero resulting in no force exerted by the truck on the trailer
The force by which the transport truck pulls on a trailer is equal to the force by which the trailer pulls the truck.
F₁ is the force by which the transport truck pulls on a trailer
F₂ is the force by which the trailer pulls the truck
F₁=F₂
A 600N [E] pulling force is applied by a transport vehicle to a trailer. Regardless of the transport truck's acceleration, the trailer pulls on it with a force of 600 N.
