The kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s is<br> J.
Jlenok [28]
Hello!

We have the following data:

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

<span>Formula to calculate kinetic energy:

</span>KE =  \frac{1}{2} *m*v^2
<span>
Solving:

</span>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! =)

The magnetic field is strong near the ____ of a magnet.
shtirl [24]

The magnetic fields of magnets are most powerful at the <u>poles of a magnet</u>. Without any difference in the magnitude, both the poles have equal amount of Magnetic field intensity at their poles.

If you see the field lines we can see the field lines start from the North Pole run parallel and end at the South Pole.  The field lines are concentrated more at the poles hence the magnetic field intensity or the magnetic field itself is more at the poles than any other part.

A boy pulls a wagon with a force of 6 N east as another boy pushes it with a force of 4 N east. What is the net force?
Angelina_Jolie [31]
The net force with be 10 N east. As both boys are pushing a wagon to the same direction, you just add the numbers together. If the directions were opposite like if it was the boy pushing 6 N east and the other boy pushing 4 N west...then it would come out as 2 N east (you subtract and go to the direction with the biggest number) if you have any confusions, feel free to ask
