Answer:
Speed, mass and acceleration
Explanation:
A scalar quantity is a quantity that has only magnitude but no direction while a vector quantity has both magnitude and direction.
According to the question, the row that has two scalars and one vector is speed, mass and acceleration.
The two scalars in this row are speed and mass while the vector quantity there is the acceleration.
Acceleration has direction since it possess direction. A body accelerating will do so in a particular direction. Speed and mass doesn't possess any direction. Mass only specify the magnitude of the body but no clue as to which direction is the body moving towards.
Speed also only specify the
total distance covered with respect to time but not the direction of the direction.

-- The mass of the sun never increases.
-- It does decrease, but not nearly enough to have any noticeable
effect on the orbital motion of the Earth, or any other planet.
-- When Earth is closer to the sun, it moves faster in its orbit.
-- When Earth is farther from the sun, it moves slower in its orbit.
-- The result is that the line from the sun to the Earth always covers
the same amount of area in the same length of time.
-- Johannes Kepler noticed this, and it's his Second Law of planetary motion.
-- Newton showed that if his equations for gravity and motion are correct,
then planets MUST behave this way.
