Answer:
Having a bigger angle above the horizontal
Explanation:
Applying the energy conservation theorem:

The kinetic energy is reduced because of the work done by the friction force.
The friction force is given by:

so the friction force depends on the Normal force, because the slide has an angle the normal force is given by:

So when the angle of the slide is bigger, the friction force decreases, for example:
for 45 degrees:

for 75 degrees:

as you can see if the angle is bigger above the horizontal, the friction force is reduced and so the work done by that force. We didn't have to change the height of the slide, so the potential gravitational energy remains the same.
I'm not sure about the magnitude, but the direction of the normal force is upward.
Metalloids are in Group 13 to 16
Answer:
Y
Explanation:
Y will produce the strongest magnetic force because the current intensity is medium and it has 50 turns in the wire. the number of turns will increase the force because the magnetic field will be more concentrated.
Have a great day :)
