Which of the following are units that can be used to describe vector qualities?
-kilometers per hour-meters-meters per second squaredA P E X (:
What are considered vectors?
In physics (at high school level, at least) vectors are quantities with both a magnitude and a direction in space. For example:ForceDisplacementVelocityAccelerationElectric fieldMagnetic fieldGravitational fieldAt a more advanced level, physics makes use of vector spaces other than the familiar 3D space we seem to inhabit. In relativity, for example, a 4-dimensional vector is used to describe energy/momentum, and another to describe the scalar/vector potentials in electromagnetism (there are many others too). In quantum theory, complex vector spaces (Hilbert spaces) are used to describe the space of states for a physical system.
Which types of measurements are used to describe quantities of heat and temperature?
Fahrenheit, Celsius, and Kelvin
Is resultant a vector quantity?
The resultant of two vectors cannot be a scalar quantity.
Give at least 10 physical quantities and their units?
Write about 10 instruments which are used to measure different physical quantities i.e. - mass, volume, time and temperature
What are units can be used to describe vector quantities?
speed and direction
Which of the units that can be used to describe vector quantities?
Units that are used for measures in which the direction is relevant. Example are displacement, velocity, acceleration, force.
What are units that can be used to describe vector quantities?
Meters per second squared, Kilometers per hour, Meters, and Miles per hour.
Can meters be used to desribe vector quantities?
yes
Is it scalar or vector when a car stops at a stop sign?
It is neither a scalar or a vector? Scalar and vectors are used to describe quantities, for example scalars include distance and mass, while vectors include weight and velocity. We do not say that a situation is a scalar or a vector.
What units can be used to describe vector qualities?
A vector quantity can be described in many different units, because there are many different vector quantities. For example, a distance - when the direction is relevant - would be indicated in meters or km. (plus a direction), a velocity in meters per second plus a direction, an acceleration in meters per second square, plus a direction. Electric field might be indicated in Volts / meter, if I remember correctly again, including an indicating the direction.
Which of the following are units that can be used to describe vector qualities?

Is this true that conversion factor is a ratio of equivalent values used to express the same units in different quantities?
No. The same quantities in different units.

How can scalar and vector quantities help people?
Scalar and vector quantities are used in mathematical models of phenomena. Accurate modeling allows people to understand these phenomena. People are helped by better understanding of the world around them.
What is the product of two vector quantities?
It depends on the type of product used. A dot or scalar product of two vectors will result in a scalar. A cross or vector product of two vectors will result in a vector.
What is dynamical quantities in quantum mechanics?
One of the quantities used to describe a system in classical mechanics, such as the coordinates of a particle, thecomponents of its velocity, the momentum, or functions of these quantities.
