Answer:
lemons, which have a pH of 2 choice a
A quantity which have both magnitude and direction is know as vector quantity.
Resultant vector is 6.81 m south east.
Triangle law of vector addition is when two vectors are represented as two sides of the triangle with the order of magnitude and direction, then the third side of the triangle represents the magnitude and direction of the resultant vector.
Since, vector K is 3.0 m north and vector L is 8.6 m southeast
So, angle between vectors K and L is,
90+45 = 135 degree
Resultant vector,
So, Resultant vector R is 6.81 m with direction of southeast.

Explanation:
Work done by gravity is given by the formula,
W = ......... (1)
It is known that when levels are same then height of the liquid is as follows.
h = ......... (2)
Putting value of equation (2) in equation (1) the overall formula will be as follows.
W =
=
= 0.689 J
Thus, we can conclude that the work done by the gravitational force in equalizing the levels when the two vessels are connected is 0.689 J.
Answer. 30 minutes
Explanation. If he walks 70 m in one minute how long will it take him to walk 2,100 m. Well, this is a simple division problem (you could also use a ratio box).
2100/70= 30. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.
