Resistance is inversely PROPORTIONAL to AREA (RADIUS)

Therefore on doubling radius resistance of wire will become HALF.

Answer:

Sir Isaac Newton FRS PRS (25December 1642 – 20 March 1726/27) was an English physicist, mathematician and astronomer. ...Newton BUILT the first practical reflecting telescope in 1668. He also developed a theory of light based on the observation that a prism decomposes white light intothe colors of the rainbow.Besides his work on universal gravitation (gravity), Newton developed the three LAWS of motion which form the basic principles of modern PHYSICS. His discovery of calculus led the way to morepowerful methods of SOLVING mathematical problems.

Hii Dear SIS!❤️

Your Answer:

250.471cm²

Explanation:

PROBLEM Given:

A copper plate has an AREA of 250cm^2 at 0°C. Calculate the area of this plate at 60°C. Given [coefficient of linear expansion of copper is alpha l=1.7×10^-5°C^-1.

Solution:

Given :

=>Copper plate area=A₀=250cm²

[I am assuming linear expansion of copper as :1.7x 10⁻⁵ C⁻¹  ]

=>Here, is the method :β=2α=2x1.7x 10⁻⁵ C⁻¹

=>3.4x10⁻⁵ C⁻¹

ΔT=>(60-0)=60°

Aθ=>A₀(1+βΔT)

A₆₀=>50(1+3.14x10⁻⁵ x60)=250(1+0.001884)=250.471cm²

Area of copper plate at 60 degree=250.471cm²

Hence,Its DONE and PROVED!

Answer:

Latent heat of vaporization is a physical property of a substance.When a MATERIAL in liquid STATE is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization.

Latent heat can be understood as heat energy in hidden form which is supplied or extracted to change the state of a substance without changing its TEMPERATURE.

Black used the term in the context of calorimetry where a heat transfer caused a volume change in a body while its temperature was constant.

ANSWER:

jisme spoon h vo FAST COOL hoga

Explanation:

because metallic spoob absorb HEAT

k = RELATIVE permittivity of the dielectric material between the plates. k=1 for free SPACE, k>1 for all media, approximately =1 for air. The Farad, F, is the SI unit for capacitance, and from the definition of capacitance is seen to be equal to a Coulomb/Volt.✔✔

In CHEMISTRY, VAPOR pressure is the pressure that is EXERTED on the walls of a sealed container when a substance in it evaporates (CONVERTS to a gas). To find the vapor pressure at a given temperature, use the Clausius-Clapeyron equation: ln(P1/P2) = (ΔHvap/R)((1/T2) - (1/T1)).✔✔

Answer:

conduction, convection, and radiation.

conduction :- the process in which heat is transferred from one place to another place without ACTUAL movement of particles of the MEDIUM.

ex :- when we heat one end of rod, the molecules at the hot get thermally agitated and transfer a part of their ENERGY to the nearly molecules etc and so on. so the other end of the rod also gets heated by conduction.

convection :- the process in which heat is transferred from one place to another place by the actual movement of the particles of the medium.

ex :- sea breezes and TRADE winds.

radiation :- the process in which heat is transferred from one place to another place without help of any material medium is CALLED radiation.

ex :- heat from the sun comes to earth by radiation.

Explanation:

To calculate the voltage drop ACROSS a RESISTOR, remember: Ohm's Law (V=I*R) is your friend. Find the current FLOWING through a resistor, then multiply the current in amps by resistance in ohms to find the voltage drop in volts.

Answer:

Explanation:

Any two forces acting on each other, which are not equal and opposite ( THEREBY causing motion ) are UNBALANCED forces. For example, when you push a wall with a force, neither you nor the wall MOVES. The wall APPLIES an equal amount of force in the opposite DIRECTION. This is an example of balanced force.

Answer:

SInce the person is standing and not moving THEREFORE distance covered is zero. Therefore work DONE is also equal to zero.

SInce there is no acceleration in the LUGGAGE therefore force APPLIED by luggage is also zero.

here's ur answer mate ➡️

speed is DEFINE as the RATE at which an object COVER a GIVEN distance in a particular time period.

SI UNIT of speed is metre per second.

EXPLANATION:

Volume of a cube = a³

if one of the SIDE = a

given a = 1.2 m

then a³ = ( 1.2 ) ³

a³ = 1.728 m³

so the volume of a cube = 1.728 m³

Explanation:

Calculation about Young's MODULUS?

modulus = stress/strain 

I commonly used as a percent of the strain.

so when i calculate young's modulus, stress is MPa and strain is %.

than modulus unit is MPa/%, isn't it?

so i think i have to do x100 the modulus value.

is it wrong??

Putting the ideal gas law, the piston, and adiabatic processes together with some fuel, we get an ENGINE Then the gas EXPANDS adiabatically, called the “power stroke,” resulting in a SUDDEN drop in the pressure and TEMPERATURE. This part of the reaction is what gives power to the car.✔✔

Answer:

48kmph

Explanation:

1st CASE:

d= 20km

s1= 40kmph

2nd case:

d=20km

s2= 60kmph

for EQUAL distance...

Avg.speed= 2/((1/s1)+(1/s2))

= 2/((1/40)+(1/60))

=(2*120)/5

=240/5

=48 KMPH

The odd one out of the given QUESTION is distance.

Option - A.

Explanation:

• Out of the given options, only distance is the quantity which doesn't match the other three options.
• Acceleration, force and velocity are all vector quantities, as the distance alone is a scalar quantity which present among them.
• The velocity, acceleration, and the force are depending on the displacement that has both magnitute and direction, so they are "vector quantity".
• Then, distance which is a scalar quantity, which refers in a motion how much meters or FEET or ground does the OBJECT covers.

To know more:

Find the odd one out. Give reasons for your choice. a) Speed, Energy , Force, Mass, Temperature b) Weight, Acceleration, Velocity, Distance, Momentum C) ROLLING Stone, Moving ball, Big table, A dancing girl, Vibrating string

brainly.in/question/4322961

Answer:

Displacement can be zero when initial and final point is same and there the distance is twice the journey .

for eg ,

going school from HOME and back home .

distance can never be zero and displacement can never be more than distance as diplacement is the shortest path b/w 2 points .

Hope it helps u

Thank u

Plz mark as brainlist

at the highest point or any other arbitrary point on its PATH of motion the VALUE of 'G' is always the same.

at the highest point or anywhere during the motion the ACCELERATION is negative.

(provided u take the upward direction as positive)

though there is a convention about velocity that at the highest point the velocity in the y direction becomes zero and only velocity along x direction is present.

Hope this HELPS.

As speed A = B = 20m/s

if the speed is same than , the DISTANCE and time is also same.

Therefore , meeting point =
