Novay_Z [31]4 years ago
4 0

Answer:

Explanation:

Given

Initial reading on scale =40 N

So, we can conclude that weight of the sack is 40 N

After this a 10 N force is applied upward on the sack such that the net force becomes (40-10) N downward (because downward force is more)

This net downward force is the resultant of earth graviational pull and the applied upward force.

So, this downward force acts on the machine which inturn applies an upaward force of same magnitude called Normal reaction.

This situation can be diagramatically represented by figure given below

A proton moving along the positive x-axis enters an electric field that is directed along the positive y-axis. What is the direc
katrin2010 [14]

Answer:

Direction of the electric force acting on the proton after it enters the electric field is along the positive y-axis.

Explanation:

In an electrical field electrical field lines goes from positive to negative. Therefore, electrical force vector is on exactly the same way with electrical field lines for a proton. Which means if the electrical field directed along the positive y-axis, electrical force for proton will be on the same way.

If a magnet could swing freely, what would happen to its north-seeking pole?
maksim [4K]

You clearly identified the pole you're talking about as the
"north-seeking" pole.  Assuming your integrity and sincerity,
we would then naturally expect that pole to seek north, and
point to Earth's north magnetic pole. 

I'm confident in this answer also because I have several of
these devices hanging from the ceiling of my office, and I can
attest to the fact that on most clear days, they do in fact point
toward Earth's north magnetic pole.
