Answer:
2.9*10^14 electrons
Explanation:
An Ampere is the flow of one Coulomb per second, so 35 μA = is 35*10^-6 C per second.
An electron has a charge of 1.6*10^-19 C.
35*10^-6 / 1.6*10^-19 = 2.9*10^14 electrons
So, with a current o 35 μA you have an aevrage of 2.9*10^14 electrons flowing past a fixed reference cross section perpendicular to the direction of flow.
Answer:
1) This is because too much fuel is needed to get a payload from the surface to orbital altitude an accelerated to orbital speed.
2) This is because space travel present extreme environment that affect machines operations and survival.

Answer:
Civil Engineering.
Explanation:
Civil Engineering is a field of engineering study that deals with professional practising in designing and developing infrastructures such as transport system and networks, buildings, etc.
<u>Civil engineering is regarded as the second--oldest form of engineering studies in the field of engineering.</u>
<u>A person who studies civil engineering is able to design and develop major projects in transportations system such as road construction, bridges, airports, tunnels, etc.</u>
So, Danny, who is interested in studying transporation networks and system should opt for studying civil engineering.
Answer:
Waterfall model
Explanation:
The waterfall model is amenable to the projects. It focused on the data structure. The software architecture and detail about the procedure. It will interfere with the procedure. It interfaces with the characterization of the objects. The waterfall model is the first model that is introduced first. This model also called a linear sequential life cycle model.
The waterfall model is very easy to use. This is the earliest approach of the SDLC.
There are different phase of the waterfall:
- Requirement analysis
- System Design
- Implementation
- Testing
- Deployment
- Maintenance
-
