What is an equipotential surface? Why two equipotential surfaces cannotintersect?

Answer»

ANSWER:

They cannot intersect each other because two different equipotential surface have different electric potential, so if they intersect then the POINT of INTERSECTION will have twodifferent POTENTIALS at the same point which is not possible. Because electric field lines can't point to two directions at the same point.

In a Geiger-Marsden experiment, what is the distance of closest approach to the nucleus of a 7.7 MeValpha-particle before it comes momentarily to rest and reverses its direction?WHAT IS Z VALUE..SPAMMERS BE AWAY...IF FOUND WILL BE BANNED..❌​

Answer»

Answer:

Closest distance of approach of alpha particle towards GOLD nuclei is

r = 1.48 \times 10^{-14} m

Explanation:

In this EXPERIMENT alpha particles are PROJECTED towards the nuclei of gold

so here INITIAL kinetic energy of alpha particle is converted into electrostatic POTENTIAL energy of alpha particle + gold nuclei

So we will have

\frac{k(e)(ze)}{r} = KE

\frac{(9\times 10^9)(1.6 \times 10^{-19})^2(79)}{r} = 7.7 \times 1.6 \times 10^{-13}

\frac{1.82 \times 10^{-26}}{r} = 1.23 \times 10^{-12}

r = 1.48 \times 10^{-14} m

- Give two differences between travelling and standing waves.​

Answer»

Answer:

(I) Travelling waves TRANSPORT energy from one area of space to another, whereas standing waves do not transport energy.

(ii) The most striking feature of standing waves is that they only occur for certain frequencies. Travelling waves on the other hand actually MOVE from PLACE to place, TRANSPORTING energy.

What is hybridization?explain the formation of Becl2 molecule using hybridisation.​

Answer»

ANSWER:

hybridisation is a phenomenon of intermixing of atomic ORBITALS of almost equal ENERGY which are PRESENT in the outer shells of the atom and their reshuffling or redistribution into the same number of orbitals but with equal properties like energy and shape.

Explanation:

be has electronic configuration 1s2,2s2.it has no unpaired electrons. it is EXPECTED not to form covalent bonds,but it forms two covalent bonds one each with two chlorine atoms. to explain this,an excited state is suggested for beryllium in which an electron forms '2s' shifts to 2Px level.

if Be forms two covalent bonds with two chlorine atoms, one bond should be sigma2s-3p due to the overlap of '2s' orbital of Be, the '3Pz' orbital of one chlorine atom and the other bond should be sigma2s-3p due to the overlap of '2Px' orbital of Be atom the 3p orbital of the other chlorine atom.as the orbitals ovelapping are different, the bond strength of two Be-Cl must be different.but,both bonds are of same strength and Cl^BeCl is 180°.

How convert speed of light into km per hour? Plzzzzzzzzz help me......its very important..

Answer»

ANSWER:

10.8 × 10⁸ KM hr⁻¹ is the correct answer.

Explanation:

To convert the SPEED given in m s⁻¹ into km hr⁻¹, we have to multiply 18/5 to the speed given in m s⁻¹.

To convert the speed given in km hr⁻¹ into m s⁻¹, we have to multiply 5/18 to the speed given in km hr⁻¹.

∴ Speed of light in m s⁻¹      = 3 × 10⁸ m s⁻¹

∴ Speed of light in km hr⁻¹  = 3 × 10⁸ × 18/5

                                              = 10.8 × 10⁸ km hr⁻¹        ←ANSWER

an athlete completes one round of a circular track of diameter 49m in 20 seconds. calculate the distance covered and displacement at end of 30 second​

Answer»

Answer:

Given , diameter of circular path = 49m

so, radius r = 49/2 m

now , distance covered by athlete

= 2πr = 2 × 22/7 × 49/2

= 154 m

so, athlete covered 154 m in 20 sec

now, at 30 second

the athlete covered πr of circle

so, displacement = diameter of circular pat

therefore , displacement = 49m

hence, distance = 154 m &

displacement = 49 m

What is dark matter ?(ONLY FOR GENIOUS)​

Answer»

\bf\large\mathfrak\red{\underline{Your\:Answer}}

Hey! GOOD Question!

Recently, scientists have come up with some new scientific theories. It has been found out that, the total gravitational force that exists in our universe is much more than the force of gravity that should be exerted by the VISIBLE celestial bodies ( according to calculations) . That's why they have come to the conclusion that there must be huge amount of matter present in our universe which is not visible to us.

Dark matter may be present all around us but we can neither SEE it nor sense it in any WAY. Many scientists are trying to FIND various ways to prove the existence to dark matter; it is still a theory till now. Scientists are trying to know more about dark matter and dark energy.

Hope very soon we can know more about it!

Hope this helps uh!

racing car initially at rest picks up a velocity of 180 kilometre per hour in 4.5 second calculate acceleration​

Answer»

Answer:

ACCELERATION = 11.111 m/s^2

Explanation:

According to the question;

initial velocity( U) = 0 m/s

final velocity ( V) = 180 km/h = 50 m/s

time ( t) = 4.5s

According to Newton's first equation of motion

acceleration =( v - u )/t

= 50-0/4.5

= 50/4.5

= 11.111 m/s^2
