1) What is the basis of absolute co-ordinate point?
Explanation:
To calculate how long it will take for a 100-watt bulb to consume 1 kilowatt-hour (kWh) of energy, we can use the formula:
time (in hours) = energy (in kWh) / power (in watts)
Here, we know that the energy is 1 kWh and the power is 100 watts, so we can plug in the values:
time (in hours) = 1 kWh / 100 watts
To convert the energy from kWh to watt-hours, we can multiply by 1000 time (in hours) = (1000 watt-hours) / 100 watts
time = 10 hours
So it will take 10 hours for a 100-watt bulb to consume 1 kWh of energy.
2) What is the basis of incremental co-ordinate system?
Explanation:
The point through which the Whole mass of the body acts, irrespective of the position of the body, is known as centre of gravity (briefly written as c.g.). The plane geometrical figures (like rectangle, triangle, circle etc.) have only areas but no mass. The centre of area of such figures is known as centroid or centre of gravity of the area of the body. It may be noted that every body has one, and only one, centre of gravity.
Mass affects the centre of gravity of the object.
3) How the points are marked in polar co-ordinate system?
4) Which letter the origin indicates in co-ordinate geometry?
Explanation:
The point through which the Whole mass of the body acts, irrespective of the position of the body, is known as centre of gravity (briefly written as c.g.). The plane geometrical figures (like rectangle, triangle, circle etc.) have only areas but no mass. The centre of area of such figures is known as centroid or centre of gravity of the area of the body. It may be noted that every body has one, and only one, centre of gravity.
Centre of gravity of a circle lies at its centre.
5) How the co-ordinate system specifies each point uniquely in a plane by?
Explanation:
The point through which the Whole mass of the body acts, irrespective of the position of the body, is known as centre of gravity (briefly written as c.g.). The plane geometrical figures (like rectangle, triangle, circle etc.) have only areas but no mass. The centre of area of such figures is known as centroid or centre of gravity of the area of the body. It may be noted that every body has one, and only one, centre of gravity.
Centre of gravity of a right circular cone from its base is at a distance of h/4.
