Cartography (the making of maps and charts) is a science because it is a body of knowledge which can be used, built on, and can produce testable hypotheses.
The cartography of India begins with early charts for navigation and constructional plans for buildings. Indian traditions influenced Tibetan and Islamic traditions, and in turn, were influenced by the British cartographers who solidified modern concepts into India's map making
Answer:
Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.
Explanation:
none
Answer:
C. 8I.
Explanation:
As moment of inertia for a bar is proportional to the product of its mass and the square of its length, doubling the mass will double the moment of inertia. Doubling the length will quadruple the moment of inertia. Doing both will make the moment of inertia 2(4) = 8 times larger
Paul the penguin's velocity is 3.33.
<u>Explanation:</u>
Paul glided (displaced) 40 meters towards north.
The time he taken to displace is 12 seconds.
∴displacement d= 40m.
time t= 12s.
The speed of a body in a certain direction is the measure of Velocity.
The velocity of the an moving object is given by ratio of the rate of change in the distance by the time taken.
⇒Velocity v= .
=.
=3.33 .
Thus the velocity of the Paul the penguin glided on ice is 3.33 .
