Answer:
The FEM is a general numerical method for solving partial differential equations in two or three space variables (i.e., some boundary value problems). To solve a problem, the FEM subdivides a large system into smaller, simpler parts that are called finite elements.
Answer:
Technician be says that diesel engines produce more power because they use excess air to burn feel who is correct
Explanation:
He is correct as many engines are run by diesel. It produces more power as that is how cars produce more power.
The impact behavior of plastic materials is strongly dependent upon the temperature. At high temperatures, materials are more ductile and have high impact toughness. At low temperatures, some plastics that would be ductile at room temperature become brittle.
Answer:
1000 Mega Ohms.
Explanation:
One mega Ohm is equal to 1,000,000 ohms, which is the resistance between two points of a conductor with one ampere of current at one volt. The mega Ohm is a multiple of the Ohm, which is the SI derived unit for electrical resistance. In the metric system, "mega" is the prefix for 10 raised to the power of 6.
Answer:
Explanation:
Given
--- Initial altitude
-- Altitude after 16.5 seconds
--- Acceleration (It is negative because it is an upward movement i.e. against gravity)
Solving (a): Final Speed of the rocket
To do this, we make use of:
The final altitude after 16.5 seconds is represented as:
Substitute the following values:
and 
So, we have:
Collect Like Terms
Make u the subject
Solving (b): The maximum height attained
First, we calculate the time taken to attain the maximum height.
Using:
At the maximum height:
--- The final velocity
So, we have:
Collect Like Terms
Make t the subject
The maximum height is then calculated as:
This gives:
Hence, the maximum height is 1141.07ft
