Which scenario describes the damage caused by a tornado?
9966 [12]

The answer is a path of destruction up to 50 miles long with destroyed trees and homes.

Tornadoes form from severe thunderstorms. Wind in the higher altitude of the storm moving at a greater velocity than wind at a lower altitude creates a vertical wind shear. The faster-moving winds aloft come from the west and create an updraft when they meet slower-moving wind close to the ground that is moving in the opposite direction. As warm surface air moves upward into the thundercloud, the rotating air creates a vortex.

The image below shows before and after damage of a tornado.

What is the weigh in newtons of an automobile with a mass of 1800 kg?​
Allushta [10]

Answer:

The weight of an automobile, W = 17640 N

Explanation:

Given that,

The mass of an automobile, m = 1800 Kg

The weight of an object is represented as the gravitational force acting on an object of mass 'm'. It given by the formula

                                   W = m x g   newton

Where,

                  g - acceleration due to gravity.

Substituting the given values in the above equation

                                   W = 1800 Kg x 9.8 m/s²

                                       = 17640 N

Hence, the weight of the automobile, W = 17640 N

Un hombre parado en el techo de un edificio, tira una bola verticalmente hacia arriba con una velocidad de 12m/s, la bola llega
zmey [24]

Respuesta:

24m

Explicación:

Según la ecuación de movimiento

v = u + en

Dado

Velocidad final v = 12 m / s

velocidad inicial u = 0 m / s

tiempo t = 4s

Sustituir

12 = 0 + 4a

a = 12/4

a = 3 m / s²

Lo siguiente es obtener la distancia;

S = ut + 1 / 2at²

S = 0 (4) + 1/2 (3) (4) ²

S = 3 * 16/2

S = 48/2

S = 24 m

Por lo tanto, la distancia requerida es de 24 m.
