<h3><u>Answer;</u></h3>
Isomers
<h3><u>Explanation</u>;</h3>
- <em><u>Isomers are compounds with the same molecular formula but different structural formula. They have the same molecular formula, but have a different arrangement of the atoms in space.</u></em>
- isomerism excludes any different arrangements which areas a result of the molecule rotating as a whole, or rotating about particular bonds.
- Isomerism may be structural isomerism where atoms are arranged in different order, or may be chain isomerism which occur as a result of branching in carbon chains.
Mass of car, m = 4060 kg
Spring constant, k = 8.00 x 10⁶ N/m
Spring compression, x = 3.72 cm = 3.72 x 10⁻² m
Let the car strike the wall with speed v m/s.
The kinetic energy of the car is released into the stored energy of the spring (if losses are ignored), so that
(1/2)mv² = (1/2)kx²
(4060 kg)*(v m/s)² = (8 x 10⁶ N/m)(3.72 x 10⁻² m)²
4060 v² = 1.1701 x 10⁴
v = 1.6513 m/s
Answer: 1.65 m/s (nearest hundredth)
Answer:
0.30581
0.24464
Explanation:
= Coefficient of static friction
= Coefficient of kinetic friction
= 75 N
= 60 N
Normal force
Frictional force
The coefficient of static friction is 0.30581
Kinetic force
The coefficient of kinetic friction is 0.24464
The surface of the coolest star is Blue I believe.
Answer:
Explanation:
The five steps used for solving design problems are:
1. Define the problem
2. Gather pertinent information
3. Generate multiple solutions
4. Analyze and select a solution
5. Test and implement the solution
1. The first step of engineering design is to identify the problem.
2. The inputs to this activity include the research the problem, perhaps supplemented with evaluate possible solutions, both produced during product design.
3. In terms of the software life cycle, engineering design occurs during the protype creation and selection phase.
4. A good way to engage the problem during this activity is to test and evaluate the protype, which produces the main outputs of this activity.
