7 0

Answer: Find the answer in the explanation

Explanation: Given the Roman numeral and the representation

I. part of a coal-fired power plant

II. part of a nuclear power plant

III. part of a coal-fired power plant and part of a nuclear power plant

a.) Boiler : I

b.) Combustion chamber: I

c.) Condenser: I

d.) Control rod: II

e.) Generator: III

f.) Turbine: III

Toward the end processes part of both coal fire and nuclear power, they both make use of turbine and generator to generate electricity.

It takes me 12s to lift a box upward with 20 N of force to a height of 45m. What was my power output ?
Finger [1]

Answer:

75Watts

Explanation:

Given parameters:

Time  = 12s

Force applied  = 20N

Height  = 45m

Unknown:

Power output  = ?

Solution:

Power is defined as the rate at which work is done.

 It is mathematically expressed as;

        Power  = \frac{work done}{time}

Work done  = force x distance  = 20 x 45  = 900J

        Power  = \frac{900}{12}   = 75Watts

Pertaining to simple machines and levers what changes when the fulcrum position is modified
ladessa [460]

Explanation :

Simple machines makes our work easier. Lever is one of the simple machine which consists of rigid rod that is pivoted at a fixed support called as Fulcrum.

There are three classes of lever.

Class 1 : In this type of class, fulcrum is placed in between effort and load. Hence the movement of load is in reverse direction of the movement of effort. (fig 1)

Class 2 : In this type of, the load is between the effort and the fulcrum. Hence, the movement of load is in same direction as that of the effort. (fig 2)

Class 3 : In this type of lever the effort between the load and the fulcrum. Hence, both the effort and load are in same direction. (fig 3)

Hence, when the position of fulcrum is modified the effort force changes.

(a) Calculate the self-inductance of a solenoid that is
adell [148]

Answer:

a) 0.142mH

b) 14mV

Explanation:

the complete answer is:

(a) Calculate the self-inductance of a solenoid that is <ghtly wound with wire of diameter 0.10 cm, has a cross-sec<onal area of 0.90 cm2 , and is 40 cm long. (b) If the current through the solenoid decreases uniformly from 10 to 0 A in 0.10 s, what is the emf induced between the ends of the solenoid

a) the self inductance of a solenoid is given by:

L=\frac{\mu_o N^2 A}{L}

μo: magnetic permeability of vacuum = 4\pi*10^{-7}N/A^2

A: cross sectional area = 0.9cm^2=9*10^{-5}m

L: length of the solenoid = 40cm = 0.4m

The N turns of the wire is calculated by using the diameter of the wire:

N = (40cm)/(0.10cm)=400

By replacing in the formula you obtain:

L=\frac{(4\pi *10^{-7}N/A^2)(400)^2(9*10^{-5}m^2))}{(0.4m)}=1.42*10^{-4}H

the self inductance is 1.42*10^{-4}H = 0.142mH

b) to find the emf you can use:

emf=L\frac{\Delta I}{\Delta t}=(1.42*10^{-4}H)\frac{10A-0A}{0.10s}=0.014V=14mV

the emf induced is 14mV
