It is False in applying the pythagorean theorem to vector addition, the resultant vector is given by the perpendicular vector
<h3>What is Pythagoras theorem ?</h3>
A useful technique for figuring out the outcome of adding two (and only two) vectors that form a right angle to one another is the Pythagorean theorem. The technique cannot be used to combine more than two vectors or to combine vectors that are not at a 90-degree angle.
- The Pythagorean Theorem demonstrates how the side lengths of a right triangle can be calculated from the sum of the areas of three intersecting squares. This theorem is a very helpful tool that serves as the foundation for more intricate trigonometry ideas like the Pythagorean theorem's opposite.

Answer:
42km/h
Explanation:
Change in km/ Change in time
1.4 x 100
0.033 x100
140km/3.3
= 42.4242 --> 42km/h

Answer:
Explanation:
i )
In a conservative field like gravitational field , loss of potential energy or work done , depends upon the initial and final point and not the manner in which 2 nd point has been reached . Since the initial and final point is same in both the cases of straight and curved path , final velocity will remain same for both of them .
Hence , due to increased mass of larger child , his kinetic energy will be greater .
ii ) Since the initial and final point is same in both the cases of straight and curved path , final velocity will remain same for both of them .
iii ) Smaller child undergo free fall , therefore , he will fall with acceleration g . The larger child falls on curved path . So , he will have only a component of
vertical g at any moment . hence average acceleration will be less.
