Is power scalar or vector quantity?
Power is a scalar quantity because it only involves the magnitude of the force and the velocity of an object, without considering direction. It is measured in watts (W).
Are Time and velocity are both vectors?
yes they are both vectors because i am married but cheating (hoe) The Answer for Apex is false
Is emf a scalar or vector quantity?
Emf has direction within a current loop, though it is not scalar. It's a bit between though as direction should be otherwise accounted for when discussing induced Emf. Not quite either.
Can displacement be equal to total distance traveled by an object?
Yes,the magnitude of both distance and displacement can be same provided the body continues to travel in a straight line and in the same direction. However you should remember that displacement is a vector quantity while distance is a scalar quantity so they both can be compared only by there magnitude.
Is electric charge scalar or vector quantity?
Charge is a Scalar Quantity as it only have Magnitude not Direction.Like in 10 Coulomb of Charge, it has 10 as magnitude and Coulomb as Unit. But this is not showing any information which tell us that it is in a particular direction.
Should a force have a direction?
Yes, it is vector with magnitude and direction
Is distance a vector quanity?
Distance is a scalar quantity, not a vector quantity. Scalars have only magnitude, while vectors have both magnitude and direction. Distance measures the length between two points and does not specify the direction of the displacement.
Is stress scalar or vector quantity?
Stress is tensor quantity. The stress tensor has 9 components. Each of its components has a magnitude (a scalar) and two directions associated with it.
What are five examples of describing work in physics?
Work is done when a force acts on an object and causes it to move in the direction of the force. Work is the transfer of energy from one system to another by mechanical means. The work done by a force is given by the product of the magnitude of the force and the distance over which it acts in the direction of the force. Work is a scalar quantity, meaning it has only magnitude and no direction. Work can be positive, negative, or zero depending on the angle between the force and the direction of motion of the object.
Why pressure is scalar quantity where as force is vector quantity?
Pressure is the force acting in all directions on an area while force is a push or pull in a direction. To understand this, we have to know how pressure or force originates. While the force is applicable to rigid materials, the term pressure is applicable for bulk materials (like water) where individual particles are considered as soft. When a force is applied from one direction on the soft particle, the soft particle gets distorted and projects out in all directions. Pressure thus do not have any unique direction but all, while a force has a unique direction. When a bomb blasts, it effects in all directions in air whereas if a running car hits, it effects in the specific direction only. A parameter effecting in all directions uniformly is considered as if it is a scalar. The pressure acts to all the directions uniformly. I mean in 360 degrees. So, we can't define a direction for pressure. The formula P= F/A is only the magnitude relation, not direction. It should be kept in mind. Mathematically, it can be understood as pressure is the ratio of force and vector area (which has direction along the normal to the surface upon which the force is acting, and if the force is not normal to to the surface we take component of force along normal. )
What is a unit of measurement?
A unit of measure is a way of describing a standardized quantity of something.Some examples of units of measure you should be familiar with:Distance/LengthfeetmilesmetersMasskilogramsForcefoot-poundsnewtons
What should a meaningful measurement have?
measurement value (magnitude of the quantity) and a proper unit.
