The answer is A. Kinetic energy is moving energy and Potential energy is building up energy. So I believe it is A.

Answer: Creative thinking

Explanation:

It should be noted that, Creative Thinking is the method by which a problem is solved with the help of thinking skills.

The thought that is present in mind is tries in the practical life so that the problem can be solved.

Going by the question asked, Mandleev was trying to arrange elements in a logical way. He thought of arranging the elements based on the atomic weight.

This gives a good oexample of creative thinking in which the thinking is applied and a logical result is product of the thinking.

The kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s is J.

Jlenok [28]

Hello!

We have the following data:

KE (Kinetic Energy) = ? (in Joule)
m (mass) = 0.5 Kg
v (speed) = 10 m/s

Formula to calculate kinetic energy:

 $KE = \frac{1}{2} *m*v^2$

Solving:

 $KE = \frac{1}{2} *m*v^2$

$KE = \frac{1}{2} *0.5*10^2$

$KE = \frac{1}{2} *0.5*100$

$KE = \frac{50}{2}$

$\boxed{\boxed{KE = 25\:Joule}}\Longleftarrow(kinetic\:energy\:of\:a\:ball)\end{array}}\qquad\quad\checkmark$

I hope this helps! =)

a=vf-vi/t is the equation for calculating the acceleration of an object. write out the relationship shown in the equation using

nevsk [136]

Answer:

Acceleration is defined as the ratio between the change in velocity of an object and the time it takes for the object to change the velocity.

In formula, this is written as:

$a=\frac{v_f -v_i}{t}$

where

vf is the final velocity

vi is the initial velocity

t is the time it takes for the object to accelerate from u to v

Note that acceleration is a vector, so it can also be caused by a change in the direction of the velocity, not only by a change in its magnitude.
