Electromagnets

When an electric current flows in a wire, it creates a magnetic field around the wire. This effect can be used to make an electromagnet. A simple electromagnet comprises a length of wire turned into a coil and connected to a battery or power supply.

Si se aplic una fuerza de 150N en un área de de 0.4m2¿cual será la preciosa ejercida?

natali 33 [55]

Answer:

P = 375 Pa

Explanation:

The question says that,"If a force of 150N was applied in an area of 0.4m², what will be the precious exerted?"

We have,

Force, F = 150 N

Area, A = 0.4m²

We need to find the pressure exerted. We know that,

Pressure = forece/area

So,

$P=\dfrac{150\ N}{0.4\ m^2}\\\\P=375\ Pa$

So, the required pressure is equal to 375 pa.

An airplane maintains a speed of 627 km/h relative to the air it is flying through as it makes a trip to a city 787 km away to t

amid [387]

Answer:1.33 hr

Explanation:

Given

Speed of airplane relative to air=627 km/h

Distance traveled =787 km

Speed of wind=38.4 km/h

Wind is blowing in opposite direction therefore net speed is

$v_{net}=627-38.4=588.6 km/h$

thus time taken is

$t=\frac{distance}{speed}$

$t=\frac{787}{588.6}=1.33 hr$
