ANSWER:

Huygens' PRINCIPLE, in optics, a statement that all points of a wave front of LIGHT in a vacuum or transparent medium may be regarded as new sources of wavelets that expand in every DIRECTION at a rate DEPENDING on their velocities.

Answer:

According to our principle, when an object is slowing down, the acceleration is in the OPPOSITE direction as the velocity. Thus, this object has a negative acceleration. ... When an object is SPEEDING up, the acceleration is in the same direction as the velocity. Thus, this object ALSO has a negative acceleration.

ANSWER:

since,the wavelenghts are equal so velocity of PROTON is equal to the electron's velocity.

LET,velocity of proton=velocity of electron=v

Also,let mass of electron be m.

Then mass of proton=1836m(Given)

So,ratio of their Momentum(Proton to electron)=1836m*v

––––––– = 1836:1

MV

And ratio of their K.E=(0.5*1836m*v²)/(0.5*m*v²)=1836:1

The SI units of ELECTRIC field are newtons per coulomb, or N C-1. A little later, HOWEVER, we shall come across a unit called a volt, and shall LEARN that an alternative (and more USUAL) unit for electric field is volts per METRE, or V m-1

Answer:

In mathematics, physics, and engineering, a Euclidean vector (sometimes called a geometric[1] or SPATIAL vector,[2] or—as here—simply a vector) is a geometric object that has magnitude (or length) and direction. Vectors can be added to other vectors according to vector algebra. A Euclidean vector is frequently represented by a line segment with a definite direction, or graphically as an arrow, connecting an initial POINT A with a terminal point B,[3] and denoted by {\displaystyle {\overrightarrow {AB}}.} {\overrightarrow {AB}}.

A vector is what is needed to "carry" the point A to the point B; the Latin word vector means "carrier".[4] It was FIRST used by 18th century astronomers investigating planetary revolution around the Sun.[5] The magnitude of the vector is the distance between the two points and the direction refers to the direction of displacement from A to B. Many algebraic operations on real numbers such as addition, subtraction, multiplication, and negation have close analogues for vectors, operations which obey the familiar algebraic laws of commutativity, associativity, and distributivity. These operations and associated laws QUALIFY Euclidean vectors as an example of the more generalized concept of vectors defined simply as elements of a vector space.

Vectors play an important role in physics: the velocity and acceleration of a moving object and the forces acting on it can all be described with vectors. Many other physical quantities can be usefully thought of as vectors. ALTHOUGH most of them do not represent distances (except, for example, position or displacement), their magnitude and direction can still be represented by the length and direction of an arrow. The mathematical representation of a physical vector depends on the coordinate system used to describe it. Other vector-like objects that describe physical quantities and transform in a similar way under changes of the coordinate system include pseudovectors and tensors.

A lightning conductor is a device used to PROTECT BUILDINGS from the damaging effect of the lightning. ... The lightning conductor works on the principle of induction, such that when a CHARGED cloud PASSES by the building, the conductor gets charge X opposite to that of the cloud through the PROCESS of induction.
