Answer:

C

Explanation:

One of the disadvantages of solar cells is that electricity storage systems are not readily available. Excess energy generated by the solar panels are wasted except they are stored by solar batteries for later use. There are various systems for storing electricity from solar cells apart from solar batteries which is the common storage system. An example of another electricity storage system for solar cell is using the water electrolyzer to store solar energy which can be used to later generate hydroelectricity.

Advantages of a solar cell includes Renewable energy, Economy-friendly and environmental-friendly energy and good durability

Without motorcycle riders are at risk of severe injury in a crash ?
nekit [7.7K]

Answer:

The correct option is;

A. proper protection

Explanation:

Motorcycle riders ride the motorcycle while at some level of speed while  having the entire body exposed to be a major part of any collision.

Injuries sustained from motorcycle accidents are several times more severe than injuries sustained by occupants of a car that is fully protected by the metallic panel in the same and even more serious accident scenarios

Hence, motorcycle riders require adequate protection by putting on available motorcyclist safety gear

Therefore, to reduce the risk of severe injury n a crash, motorcycle riders require proper protection.

In a paragraph of 125 words, distinguish the engineering design process from the reverse engineering process, citing at least th
Yuki888 [10]

The difference between the engineering design process and the reverse engineering process are there, but very subtle. The engineering design process is a process based on careful planning and months of designing to create a blueprint for a certain project. The reverse engineering process is the base of learning to create something by working backwards on a previously made inspiration for your project. Three differences are that that the engineering design process doesn't require any physical learning and is more based on mental and written learning (unlike the reverse engineering process). Another difference includes that in the reverse engineering process you don't need to take anything apart and learn how things work based on the on hands aspect of this variety of engineering. The final difference is that the engineering design project is made fresh from your own thoughts and not based off of a similar project.

A 600-MW steam power plant, which is cooled by a nearby river, has a thermal efficiency of 56 percent. Determine the rate of hea
Agata [3.3K]

Answer:

471.43MW

Explanation:

the rate of heat transfer to the power plant is determined from the thermal efficiency equation

Qh = \frac{Wout}{nth}

Qh = 600 MW / 0.56

Qh =1071.43MW

The rate of heat transfer to the river is determined from the first law related to heat engine

QL = Qh - Wout

= 1071.43 - 600

= 471.43MW

the heat will be lost to the surrounding air as it passes through pipes and other surrounding components
