Answer:

Agriculture is the basic source of food supply of all the countries of the world—whether underdeveloped, developing or even developed. ... Raising supply of food by agricultural sector has, therefore, great importance for economic growth of a country.

Explanation:

“Increase in agricultural production and the rise in the per-capita income of the rural community, together with the industrialisation and urbanisation, lead to an increased demand in industrial production”

two objects, x and y, accelerate from rest with the same constant acceleration. object x accelerates for twice the time as objec

Nana76 [90]

Answer:

X has travelled 4 times as far as Y

X is moving 2 times as fast as Y

Explanation:

Because x=1/2at²(get rid of the first portion of x=vt+1/2at² because initial v is 0 which multiplies to 0). If the acceleration is set to for example 10 (keep this constant for both X and Y) and we use t=1 and t=2 for time (as the time travelled of X is twice that of Y). Plugging this into the equation, at t=1, x=4. At t=2, x=20. 20 is four times greater than 5, so X has travelled 4 times as far as Y.

To find the difference in speed between the two objects, use the equation $v_{f}=v_{0} +at$ . Since the initial velocity is 0, that part can just be removed from the equation. With v=at, it is easy to see that if the time plugged in is twice for one than the other (and the acceleration is the same for both), the final result will be twice of the other as well. For example: If the acceleration is 10 again for both, then v=10t. If t is 1, the velocity is 10. If t is 2, the velocity is 20.

just olya [345]

The type of recommended payment will depend on the type of period and earning amount, thereby more information is required to choose one option.

<h3>Which is the type of payment?</h3>

The type of payment generally makes reference to the period in which a person earns a particular amount of money.

For example, in a salaried payment option, an employee might earn more money per week than an hourly employee.

To determine the recommended payment it is required to obtain more information about monthly/weekly and day earning options.

Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes ca

antoniya [11.8K]

The cooling rate of the substance is approximately 0.0732.

According to the statement, the Newton's law of cooling is defined by the following formula:

$T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}$ (1)

Where:

$T_{s}$ - Final temperature, in degrees Celsius.
$T_{o}$ - Initial temperature, in degrees Celsius.
$t$ - Time, in minutes.
$k$ - Cooling rate, in $\frac{1}{min}$ .
$T(t)$ - Current temperature, in degrees Celsius.

Please notice that substance reaches thermal equilibrium when $T(t) = T_{s}$ , that is when temperature of the substance is equal to the temperature of surrounding air.

If we know that $T_{o} = 80\,^{\circ}C$ , $t = 15\,min$ , $T_{s} = 50\,^{\circ}C$ and $T(15) = 60\,^{\circ}C$ , then the cooling rate of the substance is:
