Aquantity that has magnitude only is a
scalar
diagonal
vector

The correct answer is "scalar".

Explanation:

Scalar quantity: It is a physical quantity. It has magnitude only. For example, mass is a scalar quantity.

The mass of the object is 3 kg.

Speed is a scalar quantity. A car is travelling with the speed of 70 km/s.

Vector quantity: It is a physical quantity. It has magnitude as well as direction. For example, velocity is a vector quantity.

A car is travelling with 60 km/s speed in north direction.

Speed + direction= velocity

Therefore, a quantity that has magnitude only is a scalar.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
