Describe Kinetic Energy.​
mina [271]
In physics, the kinetic energy 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.

A net force of 125 n is applied to a certain object. as a result, the object accelerates with an acceleration of 24.0 m/s2. the
pantera1 [17]
Newton's second law states that Fnet = ma, where Fnet is the net force applied, m is the mass of the object, and a is the object's acceleration. You have the values for Fnet and a, so you simply use this equation to solve for m, mass.

The electric force on object A by object B is F. If the charge of object B were only half as large as it is, but everything else
nalin [4]

Answer:

The new electric force on object B by object A is one half of the magnitude of the original force F, in the opposite direction. Equals -F/2

Explanation:

We are asked to demonstrate what happens when you reduce the magnitude of the charge of an object in an interactive system.

Assumptions.

The new force is F'

The system is isolated from other external interferences

The distance between objects A and B remains unchanged

Analysis.

The force F on object A by object B is given by the formula

F=(k*q,a*q,b)/d^2

where k is the Coulomb's Law constant, and equals 9x10^9 N/m s

q,a and q,b equals the original charges of objects A and B

d is the distance between objects A and B

Now, we are to calculate the new force, let's call it F', and following the same reasoning.

F'=(k*q',a*q',b)/d'^2

Given that only q', b is different to the original, we have that

F'=(k*q,a*q',b)/d^2

Now, q',b=q,b/2 and replacing

F'=(k*q,a*q,b)/(2*d^2)

Now we find the relation between F' and F

F'/F=[(k*q,a*q,b)/(2*d^2)]/[(k*q,a*q,b)/d^2]

Reducing similar terms

F'/F=1/2

However, we should also consider that the forces F and F' are in oposite directions, so simplifying the vectorial notation,

F'/F=-1/2, meaning that F'=-F/2

When Ricky sells his used desk for $50, money is a _____.
sweet-ann [11.9K]
The answer is the first option. When Ricky sells his used desk for $50, money is a medium of exchange.<span> As you can see, money permits that Ricky gets rid of his desk (because he prefers the $50 dollars, likely to perform other purcahse) while the purchaser of the desk prefers the used desk over the $50 (likely because he needed a desk and did not want to spend more than $50). In this way, the money permits that one purchases the product that he wanted (the used desk) and permits that Ricky has money to purchase othet object that he wants.</span>
