Do balanced forces change an objects motion
meriva

If the group of all forces acting on an object is balanced,
then the effect of all of them is the same as if there were
no forces at all on the object.  In that case, the object
continues moving in a straight line at a constant speed.

There are four coils of wire being used as electromagnets. They all have the same size and are made up of the same material but
bonufazy [111]

Answer:

The coil with the maximum number of loops will produce the magnetic field with the maximum strength.

Explanation:

The magnetic field produced by a current-carrying coil at a point on the axis which is passing through its center and perpendicular to its plane is given by

\rm B=\dfrac{\mu_o N I }{2}\ \dfrac{R^2}{(r^2+R^2)^{3/2}}.

<em>where</em>,

  • \mu_o = magnetic permeability of the free space.
  • N = number of loops of the coil.
  • I = current flowing through the coil.
  • R = radius of the coil.
  • r = distance of the point where the magnetic field is to be found from the center of the coil.

Now, it is given that all the four coils have the same size, means same radius R, same material, means same permeability for all the coils, and the same amount of current is passing through all the coils, means same current I.  

The magnetic field of all the four coils is differing only due to the number of loops N.

Thus, the coil with the maximum number of loops N will produce the magnetic field with the maximum strength.

A block is launched up a frictionless 40° slope with an initial speed v and reaches a maximum vertical height h. The same block
Strike441 [17]

Answer: 1. h

Explanation:

The block would reach exactly the same height from the ground. It would travel a greater distance away from the source, but the height away from the earth would remain the same as you are giving it the same energy each time. Therefore, it will reach the same gravitation potential energy.

Another approach to look at it this is seeing it when the Block moves up the slope, its kinetic energy decreases and the potential energy increases. In both cases, the kinetic energy decreases by same amount, therefore the block rises to same height H.

Try to use the formula;

1/2MV2 = mgh

Where V = √(2gh)

I hope this helps
