Any 10 examples of dot product and any 10 examples of cross product for physics

Expert Solution

DOT PRODUCT: When two vectors are multiplied with each other and the result is a scalar (i.e., No direction) quantity then itt is called dot product.

Examples:

Workdone W = Force . Distance

Power = Force . Velocity

Electric Flux = Electric intensity . Area

A . B = B . A

i . i = 1 & i . j = 0

VECTOR PRODUCT : When two vectors are multiplied with each other and the result is a Vector (i.e., direction) quantity then itt is called vector product.

Examples:

Torque = Force X Radius

Velocity (Tangential) = Radius X Angular Velocity

Force on a charge in magnetic field = charge Velocity X Magnetic Field

A X B = l A l l B l sin Theta X Unit Vector ( According to Right Hand Rule)

A X B = - B X A

i X J = K & J X i = - k

Using definitions of dot product and cross product, show that dot product and cross product are distributive (a) If the three vectors are coplanar. (b) in general. also, Is the cross product of two vectors associative i.e. A × (B × C ) = (A × B ) × C ? If so prove it. If not provide a counter example.

Do any equipotential lines cross one another?

physicsQuestions Do any equipotential lines cross one another?Do any field lines cross one another? Estimate the electric field strength at a point :(a) half way between the terminals and(b) near one of the terminals by using the relation: where AV is the potential difference between two points (for example, two points on successive equipotential lines) and AL is the distance measured along a field line. Where is the field the strongest? Where is the field the weakest?

language assembly msp430: a macro called "vdot" that calculates the "dot product" of two vectors "a" and "b", implemented as "arrays" (following the language convention "C"), of 3 elements. the macro must receive 2 pointers to the first element of each vector and return the result in R13.

Living things are constrained by the laws of physics, chemistry, and mathematics. Provide two examples of physical laws. - For each example explicitly name the law to explain what physiological processes are described by the law using specific examples. - explain why the limits of the laws constrain the function of animal bodies - - what does the law limit for each example?

I have the following question, I have no relation to the study of Physics in any way, but the question has been teasing me for some time. Please accept my poor physical terminology. Here we go... When a solid ball is thrown in a given angle with sufficient force, that ball will move in a some path. The ball will move until the energy passed to it is no longer effective against other forces affecting its movement. I have the...

Suggest to choose a product, any product you want and wish to launch it in any country of your choice, and complete a SWOT analysis. In order to do a SWOT analysis you will first have to do background research and analyze the situation.I would like you to provide some information about the background of the country, about your product idea, your target market, etc. Then, you are to write a SWOT analysis (strengths, weaknesses, opportunities and threats). Thoroughly discuss each...
