vector
Hours is a scalar quantity, as it only represents the magnitude of time elapsed and does not have a direction associated with it.
Length is a scalar quantity. By definition, a vector quantity has both magnitude (ie. length) and direction. Length does not have direction, so it is not a vector. Length is a scalar quantity. Length is a scalar quantity. yes
scalar
Surface tension is a scalar quantity, as it only has magnitude and no direction. It represents the force per unit length acting parallel to the surface of a liquid.
vector
Charge is a scalar quantity because it only has magnitude and no direction.
Hours is a scalar quantity, as it only represents the magnitude of time elapsed and does not have a direction associated with it.
A scalar times a vector is a vector.
Electric potential is a scalar quantity since work done and charge are scalars
vector
Average speed is a scalar quantity because it only has magnitude and does not have a specific direction associated with it.
Length is a scalar quantity. By definition, a vector quantity has both magnitude (ie. length) and direction. Length does not have direction, so it is not a vector. Length is a scalar quantity. Length is a scalar quantity. yes
No, electrical charge is a vector quantity because it has both magnitude and direction.
Vector quantities have both magnitude and direction, such as velocity and force. Scalar quantities have only magnitude and no specific direction, such as speed and temperature.
A vector has direction, where as a scalar does not. When you add two vectors, it is like you are moving one vector to the end of the other vector, and closing off the triangle with a vector for the third side. That third vector is the addition of the first two vectors. The new vector points in a specific direction, so it cannot be a scalar.
No, km/s is not a vector quantity. It is a scalar quantity that represents speed, which describes how fast an object is moving without specifying its direction.
