7. The diagrams below show the number of thumbtacks that were picked up by
four magnets.
Magnet A
Magnet B
Magnet C
Magnet D
Sonia, Clara, Freida and Beverly made the following conclusions based on the
diagrams above:
Sonia: A bigger magnet has a stronger pull.
Clara: A smaller magnet has a stronger pull.
Freida: The strength of a magnet depends on its size.
Beverly: The strength of a magnet does not depend on its size.
Who made the correct conclusion?​

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )

force tends to be low and long diustance masses are high

what is the actual question though?

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
