Answer:

360 W.

Explanation:

The\;formula\;to\;find\;the\;Power\;is: P=Fv

In which,

P = Power.

F = Force.

v = velocity.

So, we have to apply values in the formula.

         P=Fv

         F=10\times(10+2)N

         F=120N

         v=3\;m/s\;that\;is\;already\;given

Then,\;\;\;\;\;\;\;\;\;P=120\times3=360W

So, the following answer is correct according to the explanation.

C. Using India’s rate of natural increase shown in the table, describe how to calculate the doubling time of India’s population
Inessa05 [86]

Answer:

t \approx 49.860\,years

Explanation:

The increase rate of population is described by the following ordinary differential equation is:

\frac{dP}{dt} = \frac{P}{\tau}

Where \tau is the time constant. The solution of the differential equation is:

P(t) = P_{o}\cdot e^{\frac{t}{\tau} }

The time constant in years is found by substituting known variables:

\ln 1.014 = \frac{1}{\tau}

\tau = \frac{1}{\ln 1.014}

\tau \approx 71.927\,years

The doubling time is:

\ln 2 = \frac{t}{71.927\,years}

t = (71.927\,years)\cdot \ln 2

t \approx 49.860\,years

− Income increases − Price of complementary products decreases These changes would MOST LIKELY have which impact on the market?
bazaltina [42]

Answer:

Income increases would have a bigger impact on the market.

Explanation:

For example, if the good is an inferior good (for example Top Ramen), higher income would mean lesser demand for that good. If it is a normal good (like seafood), however, higher income would mean higher demand.

If the good is inferior (and you have a higher income) and a complementary product price decreases, your demand still wouldn't change. You'll probably buy a little less seafood and only a little bit more top ramen.
