the light must be travelling from a more dense medium into a less dense medium (ie glass to air) the ANGLE of incidence must be GREATER than the CRITICAL angle.mark my answer Brainliest answer

p=√2mEp1:p2=3:10this is the CORRECT ANSWER

The MAGNETISM of solid is originated from the electrons of atoms. Electrons are making ORBITAL MOTIONS and spin rotations. The magnetic moment generated from the orbital or spin motion of a single electron is CALLED Bohr magnetron, which is the smallest unit of magnetic moment of solids. ..

Magnetic DIPOLE, generally a tiny magnet of microscopic to SUBATOMIC dimensions, equivalent to a flow of electric charge AROUND a loop. ... Electrons circulating around atomic nuclei, electrons spinning on their AXES, and rotating positively charged atomic nuclei all are magnetic dipoles.

10 N in the opposite direction of motion.Explanation:Hi FRIEND!First, let us find acceleration of the BLOCK. We can calculate force later by the formula Force = MASS x accelerationTo find acceleration, let us use the equation of motion v^2 - u^2 = 2asHere, u = 10, v = 0 , s =5-100 = 10 a ==========> a = -10 m/s^2 (or) 10 m/s^2 in the opposite direction of velocity.Force = mass x acceleration = 1 x 10 = 10 N in the opposite direction of motion.Hope it helps!!!

PLZZ follow me ❤️❤️The First Law of Thermodynamics STATES that heat is a form of energy, and thermodynamic processes are THEREFORE subject to the principle of conservation of energy. This means that heat energy cannot be CREATED or destroyed. ... The fundamental PRINCIPLES of thermodynamics are expressed in FOUR laws.

So for nearby objects, the ciliary muscles contract and squeeze the LENS into a more convex shape. This INCREASE in the curvature of the lens corresponds to a shorter focal length. On the other HAND, a distant OBJECT (large dobject) is typically FOCUSED at a closer distance (small dimage).

I THINK the ANSWER is WHO

In Physics, there are two domains of interest MACROSCOPIC and microscopic.Macroscopic domain: It includes phenomena at the LABORATORY, terrestrial and astronomical scales.Microscopic domain: It includes ATOMIC, molecular and NUCLEAR phenomena. MechanicsElectrodynamics: Thermodynamics: Optics:

there is a definite relationship between mechanical WORK done (w) and heat produced (H). I.e. W is DIRECTLY proportional to H. W=JH. 'J' is known as mechanical EQUIVALENT of heat

In an ELECTRIC motor, the direction of current in the coil CHANGES once in each half ROTATION.

Explanation:Time period of revolution is given as, begin mathsize 11px STYLE STRAIGHT T space equals space fraction numerator 2 πm over denominator Bq end fraction end style Let  mp = mass of the proton       mα = mass of the alpha particle.       qp = charge of the proton       qα = charge of the alpha particle. For proton: time period, begin mathsize 11px style straight T subscript 1 space equals space fraction numerator 2 πm subscript straight p over denominator Bq subscript straight p end fraction equals space fraction numerator 2 πm over denominator Bq end fraction end style For alpha particle: time period, SYNTAX error from line 1 column 55 to line 1 column 96.

Solution. MOMENT of a force is the product of the force and the PERPENDICULAR distance of force from AXIS of rotation. So, ONE way to increase the moment would be to increase the distance from the axis of rotation where the force would act.Explanation:I hope you it helps you.....

hello dear Explanation:Let the 1 N force point in the x DIRECTION, thus its vector REPRESENTATION would be 1 i^ .The resultant is 1 N and is perpendicular to the initial 1 N force. The vector representation of the resultant is 1 J^ .Now let the unit vector along the direction of P N be x^ .Thus we get:1 i^ +P x^ =1 j^ or P x^ =1 j^ −1 i^ The magnitude of this vector j^ − i^ is 2 and if we plot it on the COORDINATE system we see that it makes an angle of 135 o with the horizontal.HOPE I HELPED

In general, soil CONTAINS 40-45% inorganic matter, 5% organic matter, 25% WATER, and 25% air. In order to sustain PLANT life, the proper mix of air, water, minerals, and organic material is required. Humus, the organic material in soil, is composed of microorganisms (dead and ALIVE) and DECAYING plants

ct's inertia TENDS to RESIST any change in its STATE of rest or motion. If a carpet is beaten with a STICK then the carpet begins to move. But, the particles of DUST are trying to resist their state of rest.

pv=nrt at BC POINT pressure is CONSTANT that is not changing hence temprature is directly prapotional to volume...we can see that volume is decreasing hence temp is also decresing.....

The force ACTING on a charged particle in the presence of an ELECTRIC field is given by: F=qEF=qE, where:F is the forceq is the magnitude of the CHARGEE is the electric fieldThe force acts in the same direction as that of the electric field, when the charge is positive and the opposite direction when the charge is negative.The weight of a body acts downwards and is given by:W=mgW=mg, where:W is the weightm is the mass of the bodyg is the acceleration due to gravity
