Answer:

True

Explanation:

The fundamental steps involved in the operation of a solar cell are as follows:

Light is incident on the solar cell and this light energy is absorbed by the solar cell.
The absorbed energy results in the movement of the electron inside the cell which constitutes the electric current in the cell.
Electric current flows and electricity is produced.
Hence,in solar cell the light energy is responsible for the only voltage in the cell.

What is a system that performs different functions according to a fixed schedule?

geniusboy [140]

<u>I'm pretty sure your answer is B, because Sequential Control operates during order like a schedule</u>

Sequential Control=A control system in which the individual steps are processed in a predetermined order, progression from one sequence step to the next being dependent on defined conditions being satisfied.

Tell me if I'm incorrect but, Hope this helps!

Which of the following bonding is the strongest? (a) lonic bonding (b) Metallic bonding (c) Covalent bonding with some van der W

OLEGan [10]

Answer:

(a) lonic bonding

Explanation:

The Strongest chemical bond is the ionic bond ,

Because ionic bond is bound by strong electrostatic interactions ,

The ionic bond forms crystal lattice structure which are bounded by electrostatic interactions but the covalent bond is formed by the van der waal forces .

Hence , ionic bond is stronger than covalent bond .

Typically each development platform consists of the following components, except:Select one:a.Operating systemb.System softwarec

damaskus [11]

Typically each development platform consists of the following components except compilers and assemblers

The platform development simply means the development of the fundamental software which is vital in making hardware work.

Operating system: This refers to the low-level software that communicates with the hardware so that other programs can be able to run.

System software: This is the software that's designed in order to provide a platform for the other software. Examples include search engines, Microsoft Windows, etc.

Compilers and assemblers: Compliers are sued in converting source code to a machine-level language. Assembler is used in converting assembly code to machine code.

Hardware platform: This is a set of hardware where the software applications are run.

In conclusion, the correct option is Compilers and assemblers.

An electron is traveling with initial kinetic energy K in a uniform electric field. The electron comes to rest momentarily after

KIM [24]

Answer:

The answer is below

Explanation:

a) The work done is equal to the loss in kinetic energy (KE)

Change in kinetic energy (ΔKE) = Final kinetic energy - initial kinetic energy

Final KE = $\frac{1}{2}mv_f^2$

But the final velocity is 0 (at rest). Hence:

Final KE = $\frac{1}{2}mv_f^2=\frac{1}{2}m(0)^2=0$

ΔKE = 0 - K = -K

W = ΔKE = -K

Also, the work done (W) = charge (q) * distance (d) * electric field intensity (E)

W = qEd

but q = -e, hence:

W = -e * E * d

Using:

W = ΔKE

-e * E * d = -K

E= K / (e * d)

b) The electric field is in the direction of the electrons motion
