Answer:
The resistance of the heater is 44 ohms.
Step-by-step explanation:
Given that,
Voltage of electric heater, V = 440 volts
Current drawn by the heater, I = 10 A
We need to find the resistance of the heater. It is a case of Ohm's law. Its mathematical form is given by :
R is resistance of the heater
So, the resistance of the heater is 44 ohms. Hence, this is the required solution.
Answer:
Step-by-step explanation:
Three forces A, B and C pull on ropes tied to a ring such that ring is in equilibrium.
For the ring to be in equilibrium the force must be concurrent i.e. there line of action must be passed through a single point.
There is no net force when forces are concurrent.
When all three forces are equal then they should be at angle of to each other.
The distance formula is
simply a variation of the theorem. The method is the same with the Pythagorean
however we are now dealing with 2 sets of points instead of 2 lengths. <span>
In the distance formula, the lengths are derived from the
(x1,y1)->(x2,y2) coordinate points and the formula simplified. We still
square the difference of x’s and difference of y’s to get our two squares then
square root the sum to give our length. While the Pythagorean theorem is
directly the sum of the square of the other two sides.
<span>Nevertheless, both formulas work on the same principle.</span></span>
