Answer: Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work.
Explanation:
Answer:
Heat is the energy that flows between two substances of different temperatures.
Explanation:
Heat is a type of energy in transition that is transferred by non-mechanical means between systems, which means that it is energy that is transferred (or that <u>flows </u>) from one system to another.
This flow of energy occurs due to a temperature difference, and heat will flow from the system or substance with a higher temperature to the substance with a lower temperature, and if kept in contact they will eventually reach the thermal equilibrium.
So the correct answer is: Heat is the energy that flows between two substances of different temperatures.
Heyyyy I wish I could help but I don’t know
<span>a planes engines are designed to move it forward at high speed. That makes air flow rapidly over the </span>wings<span>, which throw the air down toward the </span>ground<span>, generating an upward force called </span>lift<span> that overcomes the </span>plane's<span> weight and holds it in the sky. ... The </span>wings<span> force the air downward and that pushes the </span>plane<span> upward</span>
Answer:
The centripetal force will be 1/2 as big as it was. (option c)
Explanation:
Recall that centripetal force (
) is defined as: 
where "v" is the tangential velocity of the object in circular motion, "r" is the radius of rotation and "m" is the object's mass.
So if we start with such formula with a given mass, radius, and tangential velocity, and then we move to a situation where everything stays the same except for the radius which doubles, then the new centripetal force (
) will be given by: 
and this is half (1/2) of the original force:
which is expressed by option "c" of the provided list.
