A plane has a speed of 275 km/hr. The wind is at a 70 degree angle to the direction of the plane with a speed of 75 km/hr. What

8090 [49]

The combined speed of the plane and the wind is 249.35 km/h.

<h3>Relative speed</h3>

The relative speed of the plane due to speed of the wind is calculated as follows;

Let the direction of the plane be horizontal direction.

<h3>Speed of the wind</h3>

The speed of the wind is calculated as follows;

$V_b = V \times cos\theta\\\\V_b = 75 \times cos(70)\\\\V_b = 25.65 \ km/hr$

<h3>Combined speed</h3>

The combined speed of the plane and the wind is calculated as follows;

V = 275 km/h - 25.65 km/h

V = 249.35 km/h

Thus, the combined speed of the plane and the wind is 249.35 km/h.

Why is the overall charge on an atom neutral?

Oksi-84 [34.3K]

The overall charge on a neutral atom is zero.

A neutral atoms contains equal number of electrons and protons.The charge of a proton and electron is equal in magnitude but opposite in sign. A proton has a charge of 1.6 x 10⁻¹⁹C and the charge of an electron is -1.6 x 10⁻¹⁹C. Thus in a neutral atom, the charge of all the protons gets cancelled with the charge of all the electrons.

Thus a neutral atom has a net zero charge.
