Answer:

Explanation:

D is nonsense. The current keeps coming through all lights.

A is wrong. The exact opposite happens. More bulbs more resistance.

C is wrong. More resistance less current, not more.

So your answer is B because the voltage drop in each decreases when there are more bulbs.

Could you pick up a nail using the curved part of the horseshoe magnet farthest from the poles?

nikitadnepr [17]

Yes

Explanation:

One can pick up a nail using the curved part of the horseshoe magnet farthest from the poles.

A horse shoe magnet has magnetic fields all around it.

In the presence of magnetic force fields, any magnetic object will be attracted to it.
This is the case with any magnet.
A magnet is any object with magnetic fields all around it.
This field causes attraction to any magnetic objects especially metals.

Consider a light, single-engine airplane such as the Piper Super Cub. If the maximum gross weight of the airplane is 7780 N, the

viva [34]

Answer:

V=19.08 m/s

Explanation:

Airplane gross weight w=7780 N

Airplane wing area S=16.6 m²

Air density p=1.2250 kg/m³

Maximum lift coefficient CL=2.1

To find

Stalling Speed

Solution

The equation to find stalling speed is given below

$W=(1/2)S_{area}(V_{Stalling-speed} )^{2} (P_{Air-density} )(C_{Lmax} )\\ so\\V_{Stalling-speed}=\sqrt{\frac{2W}{S_{area}*(P_{Air-density} )(C_{Lmax} )} }\\V_{Stalling-speed}=\sqrt{\frac{2*7780}{16.6*2.1*1.225} }\\ V_{Stalling-speed}=19.08 m/s$
