Slow and steady wins the race. 4. He who follows two hares catches neither. 5. A, great.city is, to be sure..

power

By building upon the basic definition that $i^{2}$ = - 1, we can write higher powers of i as follows: $i^{0}=1,\: i^{1}=i,\: i^{2}=-1,\: i^{3}=i^{2}\times i=-i,\: i^{4}=(i^{2})^{2}=(-1)^2=1$ $i^{5}=i^{4}\times i=1\times i=i,\: i^{6}=i^{4}\times i^{2}=1\times(-1)=-1,\: i^{7}=i^{4}\times i^{3}=1\times(-i)=-i,\: i^{8}=(i..

power conservation

A mass of 4 kg is acted on by a force of 8 N for 5 s. Calculate the i) impulse or gain in momentum, ii) energy of the mass. Solution: i) Since, impulse$=Force\times time$ We have impulse $=8\mathrm{N}\times5s=40$ Ns ii) Also, F = ma, gives a = F/m So, acceleration of the mass $a=(40\mathrm{Ns}^{-1})/(4..

power center

. The radical axis of two circles is the locus of point, powers of which w.r.t.. the two, circles are equal. 17. If the equations of two circles in standard form are $\mathrm{S}_{1}=0$ and $\mathrm{S}_{2}=0$, then their radical axis is $\mathrm{S}_{1}-\mathrm{S}_{2}=0$. The radical axis is a line perpendicular to the line of ce..

power speed

The following table shows the power to the nearest kilowatt and top speeds to the nearest km/h of a sample of 12 sports cars drawn at random from the stockist : Power x(kw) : 70 63 72 60 66 70 74 65 62 67 65 68 Top speed y(km/h) ..

subtraction in base ten

In subtraction, digits from the subtrahend are subtracted from the corresponding digits from the minuends with the same positional values. If a digit from the subtrahend is greater that the corresponding digit from the minuend, one is borrowed from the immediate neighbor on the left and that one counts at ten. Ten added..

conversion to base ten

A number system to an arbitrary base can be converted to base ten in two ways by using: (a) expanded notation; (b) extended multiplication..

arithmetic in base ten

Recall that the elementary operations in arithmetic are: (a) Addition, (b) Subtraction, (c) Multiplication (d) Division Multiplication can be regarded as a repeated addition while division can also be regarded as a repeated subtraction..

Power

(1 H.P.) Even now the power of a motor is expressed in H.P. 1H.P. = 746 W Remember the following units of power which are in use. 1 1 kilo watt (kW) = lOOOwatt (W) 2 1 Mega watt (mW) = 10 6 watt 3 1 watt hour = 3600 joule 4 1 kilo watt hour = 3.6xl0 6 joule (The last two units are used as the units of electric po..
