Car's speed = 40 km/h
Time = 15 mins. = 0.25 hrs.
Distance = Speed × Time = (40 × 0.25) km = 10 km.
Car's speed = 60 km/h.
Time = 15 mins. = 0.25 hrs.
Distance = Speed × Time = (60 × 0.25) km = 15 km.
So, Total distance travelled = (10+15) km = 25 km

According to Kepler’s first law,” All the planets revolve around the sun in elliptical orbits having the sun at one of the foci”. The point at which the planet is close to the sun is known as perihelion and the point at which the planet is farther from the sun is known as aphelion.

Kepler’s second law states ” The radius vector drawn from the sun to the planet sweeps out equal areas in equal intervals of time”

According to Kepler’s law of periods,” The square of the time period of revolution of a planet around the sun in an elliptical orbit is directly proportional to the cube of its semi-major axis”.

Cellulose is a polysaacharide consisting of a linear chain of several hundred to over ten thousand glucose units. Cellulose is the structural component of the primary cell wall of green plants and many algae. Diffusion is the spontaneous movement of molecules such as oxygen, carbon dioxide etc. from a region of higher concentration to a region of lower concentration.

D 206 Subhadra Apartments New Delhi 29 Dec 2020 The Editor The Real Times New Delhi Dear Sir/Mam Subject : urgent need to take action on the insenitory condition . It is with great anguish that I am writing to you that the insanitary conditions prevailing in our locality In the absence of proper arrangements of sanitation our locality has become a store-house of filth and dirt. The streets remain unswept for weeks together and rubbish is allowed to gather in heaps at street corner, emitting foul odours. Drains, too, have not been cleared for quite a long time. The result is that they are choked with rubbish and dirty water has accumulated therein. These drains have become a breeding place for flies and mosquitoes. We have brought these things to the notice of the area Health Supervisor but with no result. If immediate steps are not taken in this connection, the conditions are sure to become a serious threat to the health of the residents of this locality. Hopefully , this letter will meet the eyes of our worthy officials , and steps will be taken regarding this issue . Yours faithfully Abc

In calculus, differentiation means dividing a whole into many parts and integration means adding up several parts into whole.

0 Thank You

Yogita Ingle 5 years ago (2577571)

Differentiation is the essence of Calculus. A derivative is defined as the instantaneous rate of change in function based on one of its variables. It is similar to finding the slope of a tangent to the function at a point.

Integration is a method to find definite and indefinite integrals. The integration of a function f(x) is given by F(x) and it is represented by:

where

R.H.S. of the equation indicates integral of f(x) with respect to x

F(x) is called anti-derivative or primitive.

f(x) is called the integrand.

dx is called the integrating agent.

C is the constant of integration or arbitrary constant.

x is the variable of integration.

Concave wheels have a center that dips inward instead of outward to create a curved, bowl-like effect. These wheels have spokes that start on the outer rim. Overall, concave wheels help you create a more modern, high end look for your vehicle without sacrificing any functionality.
