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
The formula for calculating GPE is
GPE = m x h x g
Where m is mass, h is height raised and g is gravity.
To solve the problem we just have to substitute the values we are given
70,000J = 650 x 10 x y
70,000J = 6500 x y
70,000 / 6500 = y
10.769 = y
So, the block of stone has been raised approximately 10.769 metres.
To determine the heat released by the process of condensation, we simply multiply the amount of the gas that condensed to the latent heat of vaporization. We do as follows:
Heat released = 21 J/g (12.0 g ) = 252 J of heat released
When Emmett is lifting a box
vertically, the forces that must be added to calculate the total force are: the
gravitational force, tension force(the force exerted by Emmett to the box and
the force exerted by the box to Emmett), and air resistance force.
