Why does a plane move even when the wind is pushing against it?

Answers

Answer 1

Answer: A plane has more mass in it. Also, the engine is very strong which it makes the plane able to push through the wind. When the wind is pushing, it goes by it because of the engine.

Answer 2

Answer: The airplane's engines give it a certain speed through the air, called it's "airspeed". If the airplane's airspeed is greater than the windspeed, it will move forward over the ground. If it's airspeed is less than the windspeed, it will move backward over the ground. If it's airspeed is exactly equal to the windspeed, it will hover motionless over the ground.

If a step-up transformer has a primary coil with 15 turns, how many turns would be required in the secondary coil in order to increase the voltage from 80 volts to 160 volts? A. 8 turns B. 30 turns C. 80 turns D. 160 turns

Answers

Answer:

$N_2=30turns$

So option (b) will be correct option

Explanation:

We have given that there is a step up transformer in which number of turns in primary coil is 15

That is, $N_1=15$

Primary voltage $V_1=80volt$ , and secondary voltage $V_2=160volt$

We have to find the number of turns in the secondary \

We know that for the transformer

$(N_1)/(N_2)=(V_1)/(V_2)$

$(15)/(N_2)=(80)/(160)$

$N_2=30turns$

So option (b) will be correct option

Answers

The Pacific plate collides with and is subducted under four other crustal plates. The area where this happens has lots of volcanic activity. This area is called the Ring of Fire.This is a place under the Pacific Ocean and it has numerousvolcanic eruptions and earthquakes and so this region is called the Ring ofFire. In this place there are about 450 active and dormant volcanoes and it isalmost 75 percent of the volcanoes present in our earth.

When all parts of a circuit are composed of conducting materials, the circuit is said to be A. shorted.
B. closed.
C. parallel.
D. open.

Answers

Answer:

The circuit is said to be closed

Explanation:

Electricity is defined as the movement of electrons within a conductor in a certain path.

This means that, for electricity to flow, two conditions need to be fulfilled:

1- there must be conductor materials for electrons to move through

2- a closed path (loop) must exist to allow the flow of electrons

If wither of these conditions is not met, the movement of electrons will be stopped and therefore, electricity will not be conducted

Based on the above, when all parts of a circuit are composed of conducting materials (conductors forming closed path), the circuit is said to be closed (a loop exists for electrons to move in).

Hope this helps :)

When all arts of a circuit are composed of conducting materials, it is said to be closed, so B.

The highest surface wind speeds occur when there is a

Answers

The correct answer to the question above is 20 millibar pressure difference between two near locations. The highest surface winds speed occur when there is a 2- millibar pressure difference between two nearby locations. Wind speed or also called as wind velocity is caused by the higher air pressure going to low.
