Gaaffii filannoo 10 boqonnaa kana irratti barreeffaman, tokkoon tokkoon isaanii deebii fi sababa qabu. Deebii banuu dura yaali. Gaaffiin kun Ingiliffaa tiin.
Gaaffii 1
Which of the following physical quantities is a vector quantity?
Deebii: D Weight
Sababa
According to the textbook, weight, force, and velocity are vectors because they have both magnitude and direction. Volume, temperature, and mass are scalar quantities because they have magnitude only.
Gaaffii 2
What is the resultant magnitude when two parallel vectors A = 6.8 cm and B = 5.5 cm act in the same direction?
Deebii: B 12.3 cm
Sababa
When two vectors point in the same direction, their resultant is found by direct addition: R = A + B = 6.8 cm + 5.5 cm = 12.3 cm.
Gaaffii 3
What is the name of the single vector that produces the same overall effect as two or more vectors added together?
Deebii: C Resultant vector
Sababa
The resultant vector is the result of adding two or more vectors together. The individual vectors can be replaced by the resultant where the overall effect is the same.
Gaaffii 4
Under what condition can the sum of two vectors be equal to zero?
Deebii: D When they have equal magnitudes and point in opposite directions
Sababa
The sum of two vectors can only be zero if they are equal in magnitude and opposite in direction.
Gaaffii 5
A force F = 40 N acts at an angle of 30° to the horizontal. What is the vertical component (Fy) of this force? (Note: sin 30° = 0.5)
Deebii: A 20 N
Sababa
The vertical component is calculated as Fy = F sin θ = 40 N × sin 30° = 40 N × 0.5 = 20 N.
Gaaffii 6
An athlete in Hawassa runs 6 m north and then 8 m east. What is the magnitude of the athlete's resultant displacement?
Deebii: C 10 m
Sababa
Since north and east are perpendicular, we use Pythagoras' theorem: R = √(62 + 82) = √(36 + 64) = √100 = 10 m.
Gaaffii 7
In the parallelogram law of vector addition, two vectors are joined tail to tail. Which part of the parallelogram represents their resultant vector?
Deebii: B The diagonal of the parallelogram
Sababa
When two vectors form the adjacent sides of a parallelogram by joining their tails, the sum of the two vectors is given by the diagonal of the parallelogram.
Gaaffii 8
A displacement vector has a magnitude of 2.0 m directed due east. What is the magnitude of its component along the north direction?
Deebii: C 0.0 m
Sababa
A vector that points completely along the east direction (x-axis) has no vertical part. Therefore, its component along the north direction (y-axis) is 0.0 m.
Gaaffii 9
A force vector of 10 N acts in the positive x direction. Which pair of forces acting in the negative x direction will result in a net force of zero?
Deebii: B 4 N and 6 N
Sababa
For the resultant to be zero, the total force in the negative x direction must equal 10 N. The forces 4 N and 6 N add up to 10 N in the negative direction, canceling out the 10 N positive force.
Gaaffii 10
According to the polygon law of vector addition, if several vectors are represented by consecutive sides of a polygon taken in order, how is their resultant represented?
Deebii: A By the closing side of the polygon taken in the opposite order
Sababa
The polygon law states that if a number of vectors are represented in magnitude and direction by the sides of a polygon taken in the same order, then their resultant is represented in magnitude and direction by the closing side of the polygon taken in the opposite order.
