A circular hole of diameter d = 3 m is digged on a levelled plot of land shown to a depth of 4 m and the sand so obtained is spread evenly over the rectangular portion of measurement a × b = 7 m × 14 m. What is the increase in the level of the rectangular plot? [Take..
Determination of Diameter of Moon
Let moon be the astronomical object of diameter D. Let E be the point on earth's surface. A telescope is focused on moon's surface and its image is observed as shown in figure is measured. S is the distance between moon and the Earth's surface. The diameter AB of moon is considered as a h..

The wire whose thickness is to be determined is placed between the anvil and spindle end, the thimble is rotated till the wire is firmly held between the anvil and the spindle. The rachet is provided to avoid excessive pressure on the wire. It prevents the spindle from further movement. The thickne..

Summary - Trigonometry is that branch of mathematics which deals with the measurements of sides and angles of triangles. The figure obtained by rotating a given ray about its end point is called an angle. An angle is called positive if the direction of rotation of ray from initial side to..
Consequence of second law
The second law of motion improves our understanding of most types of motion involving a force. We get to understand that if a body is pushed with a stronger force, it accelerates at a faster rate and vice versa. We understand that if two different bodies are pushed with an equal force, the product ..

Apparent Loss of Mass - You must have seen that when substances like wood, wax, coal, oil, etc. are burnt, they seem to disappear, or leave a very small quantity of residue. It looks as if the mass is much lesser. Well, the loss of some mass of these substances is only apparent. As per the Law of c..

Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
This explained everything to me clearly and helped me so much and I think it has made a difference in my understanding. Its gone from small to big understanding ,I think it is a magnificent tutoring - Elizabeth
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
I have experienced very innovative way of learning, I joined online tutoring at Tutorvista few months back when I was in grade 10, I scored really well in grade 10 and ny parents were really happy.
