Identify the type of electrification of the road

Physics
1 answer:
Arte-miy333 [17]3 years ago
6 0
Electrification is widely considered as a viable strategy for reducing the oil dependency and environmental impacts of road transportation. In pursuit of this strategy, most attention has been paid to electric cars. However, substantial, yet untapped, potentials could be realized in urban areas through the large-scale introduction of electric two-wheelers.

<span>1.    </span>Meiosis has 2 cell divisions but mitosis has only one cell division. Meiosis I is same as mitosis because parent cell produces diploid cells. But the difference between meiosis and mitosis is after the complete process meiosis produces genetically different haploid daughter cells and mitosis produces genetically same diploid daughter cells.


<span>2.    </span>The main advantage of the sexual reproduction is It helps to produce offspring which can be well adapted to the environmental conditions due to the genetically differentiations. Hence, there are various types of offspring in the population. But the disadvantage is it requires two parents and it requires more time than asexual reproduction.


<span>3.    </span>Advantages of asexual reproduction are it requires only parent, time for the process is relatively low, it produces genetically identical offspring. The main disadvantage is due to the production of genetically identical offspring, the survival rate is low when there is a disaster.


<span>4.    </span><span>The organism can do either sexual reproduction or asexual reproduction to produce offspring. If it is difficult to find a partner to mate, the living being can do asexual reproduction to make offspring in a short period of time. When the organism needs genetically different offspring for survival, they can do sexual reproduction.</span>

You open the refrigerator in your room and put in a case of room-temperature root beer. After an hour, the root beer is ice cold
agasfer [191]

Answer:

warmer

Explanation:

The law of conservation of energy tells us that energy cannot be created or destroyed, it can be transferred or converted from one from to another. In this question when the beer that is at room temperature is put in the fridge, it loses some heat energy. This heat energy is not destroyed, the fridge through  multiple processes eventually releases this heat to the room through pipes at the back which is why they are normally warm. the heat from the food inside is expelled to the room. It is not lost.

The current through an inductor of inductance L is given by I(t) = Imax sin(ωt).
sammy [17]

Answer:

(a) emf_L=-LI_{max}\omega cos(\omega t)

(b) neither increasing or decreasing

(c) opposite to the flow of charge carriers

Explanation:

The current through an inductor of inductance L is given by:

I(t)=I_{max}sin(\omega t)   (1)

(a) The induced emf is given by the following formula

emf_L=-L\frac{dI}{dt}    (2)

You derivative the expression (1) in the expression (2):

emf_L=-L\frac{d}{dt}(I_{max}sin(\omega t))\\\\emf_L=-LI_{max}\omega cos(\omega t)

(b) At t=0 the current is zero

(c) At t = 0 the emf is:

emf_L=-\omega LI_{max}

w, L and Imax have positive values, then the emf is negative. Hence, the induced emf is opposite to the flow of the charge carriers.

(d) read the text carefully

Find the noise level of a sound having an intensity of 1.5x10^-14W/m^2 given I0=10^12 W/m2
Llana [10]

Answer:

Noise level will be -18.2 watt

So option (b) will be correct answer

Explanation:

We have given sound intensity I=1.5\times 10^{-14}w/m^2

And threshold intensity I_0=\times 10^{-12}w/m^2 ( in question it is given as 10^{12}w/m^2 but its standard value is 10^{-12}w/m^2 )

Now noise level  =10log\frac{I}{I_0}=10log\frac{1.5\times 10^{-14}}{10^{-12}}=10log0.015-18.23

So the noise level will be -18.2

So option (b) will be correct answer
