A is CORRECT answer.MARK IT AS BRAINLIEST

e the coordination of BRAIN with other parys of body DECREASE DUE to which the vision of old people is WEAK

hat ,y=sin(X)  and x=3ttherefore we GET y=sin3t=>dy/dt= d(sin3t)/dt          ** we KNOW {{{  d(sinxt)/dt = xsint }}}**=> dy/dt = 3cos3t or 3cosxhope this willl help you !mark it as BRAINLIEST if you like it :)

aw states that at constant temperature when all other physical parameters remains same, the current FLOWING through a conductor is directly proportional to the potential difference across its ends.So, for ohm's law to hold GOOD CONDITION if:i) Temperature remains constant.ii) Other physical parameters i.e. length of materials, area of cross-section, shape ETC. is kept UNCHANGED.

स्था को कायम रखने की प्रकिया को INERTIA कहते हैं।The TENDENCY to be INERT is CALLED inertia.

dy!The sensation felt by our ears is called sound. It is a form of energy which makes us hear. Sound is a longitudinal wave which consists of compressions and RAREFACTIONS travelling through a medium. Sound travels in the form of wave and a wave is a VIBRATORY disturbance in a medium which CARRIES energy from one point to ANOTHER WITHOUT there being a direct contact between the two points.

of combination in which if 1 circuit get disconnected others work but it is OPPOSITE in CASE of SERIES

...how can IRON FREEZE it is ALREADY in the SOLID STATE.

/DT here F = 50×10 so 500= 5000× dm/dt dm/dt = 0.1

dinal waves are waves in which the DISPLACEMENT of the MEDIUM is in the same direction as, or the OPPOSITE direction to, the direction of PROPAGATION of the wave.

netic field between poles (see figure for MAGNETIC POLE definition) is in the opposite direction to the magnetic moment (which POINTS from the negative charge to the positive charge), while INSIDE a current loop it is in the same direction (see the figure to the right).

tan , also known as Eureka, is an alloy of copper and NICKEL , was discovered in 1887 , and has been used for resistance all along, APART from other applications.Its preference for resistance wire stems from high resistivity, low temperature coefficient of resistance, ability to attain GOOD resistance values in small size, stability, ability to draw in thin wires. It's melting point is also high at over 1200 degrees Celsius.Apart from resistance, constantan is also used in thermocouples.Manganin is an improvement over constantan, discovered in 1892. It is an alloy of copper , manganese and nickel. Its temperature coefficient of resistance is near zero, and this makes it ideal for ammeter shunt, and high precision resistance.Manganin is used in resistance standards, its melting point is around 1000 degrees Celsius, and maximum usage temperature is limited to 300 degrees Celsius.

are white because LIGHT from the sun is white. As light passes through a cloud, it interacts with the water droplets, which are much bigger than the ATMOSPHERIC PARTICLES that exist in the sky. When sunlight reaches an atmospheric particle in the sky, blue light is scattered away more strongly than other colours, GIVING the impression that the sky is blue. But in a cloud, sunlight is scattered by much larger water droplets. These scatter all colours almost equally meaning that the sunlight continues to remain white and so making the clouds appear white against the background of the blue sky.

trons can't be summed up to 1 COULOMB, what you actually mean is -1 Coulomb. So, 6.25 × 10^18 electronsmake up a total of -1 Coulomb of CHARGE.

this HELPS you!!!!

ck hole is am MYSTERIOUS celestial OBJECT that it's gravitational force is so STRONG that even LIGHT can't escape from it , but what were you asking?

YOUR ANS ...Kinetic Energy = 1/2 mv^2Numbers are generally better for comparison than variables, so I’m going to assign a few.m = 1, v = 1Therefore KE_original = 1/2 * 1 * 1^2 = 1/2(It’s against my better judgment, but I’ll leave them unitless. Don’t leave numbers unitless unless they’re meant to be. UNITS make everything better. )If the mass is quadrupled, then the new mass is 4. If the velocity is DOUBLED, then the new velocity is 2. LET’s do the math.KE_new = 1/2 * 4 * 2^2 = 8 = 16 * KE_originalLet’s think about this…Energy is directly proportional to mass:QUADRUPLE the mass → quadruple the energyEnergy is directly proportional to velocity squared:Double the velocity → quadruple the energyWith a factor of 4 from both relevant variables, it makes sense that the new energy is 16x the original.HOPE IR WRKS

your ANSWER but I am not SURE about it

nce is the property of OPPOSING the electric current through anything. There are several factors on which resistance DEPENDS which are following :-i) Resistivityii) TEMPERATUREIII) Lengthiv) Cross SECTION areaHOPE IT HELPS:-)

FORCE: The upward force exerted by any FLUID UPON a body placed in it .HOPE IT HELPS YOU!PLEASE MARK AS BRAINLIEST!!
