Arrange the steps in order to explain how a tornado forms.
Sergio [31]

Answer

The steps in order to explain how a tornado forms are;

1. An extreme difference in wind speed at two elevations causes the wind shear

2. The difference in wind speed causes a column of air to rotate horizontally

3. A strong updraft connects the rotating air with clouds above

4. The column of air stretches to form a tornado

Explanation

The typical steps of tornado formation follow the below steps;

• Occurrence of a large thunderstorm which happens in the cumulonimbus clouds

• There is a change in wind direction and speed at higher attitudes that makes the air to swirl horizontally

• Air rising from the ground pushes up on the swirling air and tips over it

• The swirling air funnel starts to suck up more warm air from the ground

• The funnel enlarges and stretches towards the ground

• The funnel touches the ground level to form a tornado

In one of the classic nuclear physics experiments at the beginning of the 20th century, an alpha particle was accelerated toward
anygoal [31]

Answer:

3.95 \times 10^{-14}m

Explanation:

We are given that

Charged on alpha particle=q=2e=2\times 1.6\times 10^{-19} C

Where e=1.6\times 10^{-19} C

Initial kinetic energy=K.E=5.76 MeV=5.76\times 10^6\times 1.6\times 10^{-9} C

1 Me V=10^6\times 1.6\times 10^{-19} V

Z=79

Charge on protons=q'=79\times 1.6\times 10^{-19} C

We have to find the closeness of alpha particle to the gold nucleus before being turned around.

Initial kinetic energy=Final potential energy

5.76\times 10^6\times 1.6\times 10^{-9}=\frac{Kq_1q_2}{r}

Where k=9\times 10^9

r=\frac{9\times 10^9\times 79\times 1.6\times 10^{-19}\times 2\times 1.6\times 10^{-19}}{5.76\times 10^6\times 1.6\times 10^{-9}}

r=3.95\times 10^{-14}m
