Sustainable product design is not an example of environmental sustainability.
<u>Explanation: </u>
- Development which meets the present needs without compromising the ability of future generations to meet their own needs is known as sustainable development.
- For the process of waste management, many lands deposited should be cleaned and preserved properly. Throwing waste in public places or plastics which is not biodegradable can affect the environment as well as living things. Proper disposal of waste should be done and many landfill processes are made for the safety of a clean environment.
- Energy optimization is a major key to environmental sustainability. Much renewable energy is practiced to improve the optimization of energy. Resource management is not only environment-related it also helps in improving the ethical, economic and scientific variables.
A. The number of protons is the same as the number as electrons, when its just a neutral atom
Answer:
It isn't safe for the car to drive on this road.
The radial acceleration of the car exceeds the maximum radial acceleration the road can support.
Explanation:
For the road to be safe for the car, frictional force of the road on the car must always exceed or match the force keeping the car in circular motion
Frictional force of the road on the car = μmg = 0.4 × 1600 × 9.8 = 6272 N
Force keeping the car in circular motion = mv²/r = 1600×27²/150 = 7776 N
The force keeping the car in circular motion > Frictional force that the road can support the car with.
Maximum radial acceleration the road can support = Frictional force/mass of the car = 6272/1600 = 3.92 m/s²
Radial acceleration of the car currently = 7776/1600 = 4.86 m/s²
which evidently exceeds the maximum allowable radial acceleration
This means the road isn't safe for the car.
Answer:
true
Explanation:
The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
