Answer:
24.9 m
Explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as the equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.
You walk 21.5 m straight east and then 12.5 m straight north. This forms a right angled triangle with a horizontal distance of 21.5 m, a vertical distance of 12.5 m and the hypotenuse is the distance between the ending and starting point. Let x represent the distance between the ending and starting point. Therefore using Pythagoras theorem:
x² = 21.5² + 12.5²
x² = 462.25 + 156.25
x² = 618.5
Taking square root of both sides:
√x² = √618.5
x = √618.5
x = 24.9 m = distance between the ending and starting point.
Physics can be used in a variety of ways, a specific example would be rollercoaster. Physics can be used to determine the speed at which a rollercoaster can travel without going off the rails or when it needs to begin to slow down to make a sharp turn.
Answer is C.
Water-holding capacity is controlled primarily by soil texture, and amount of organic matter. Soils with small particles containing clay have a larger surface are than those larger sand particles, and a large surface area that allows to hold more water.
The correct option is: Option (D) not turn at all.
Explanation:
As the bar magnet is at rest, there is no change in magnetic flux. It means the change in magnetic flux in the magnetic flux in the loop is zero. Hence the induced current in the loop is zero and the loop will never turn at all. Therefore, the correct option is (D).
