a device that protects APPLIANCES from overloading ( caused by shortcircuting). A RATED fuse has a specific WIRE of specific resistance in it. thus when there is excess CURRENT the wire will HEAT up and melt thus cutting the circuit open and protecting the other appliances connected from overloading.

tion:P = 75W I = 680 mA = 680/1000 A Q = 30 coulombs P = VI => V = 75 x 1000 / 680 => V = 110V ( ROUNDED off) W = qV = 30 x 110= 3300J T = W/P= 3300 / 75= 44 seconds ( approx) Or you can directly do it this way :-t = q/I= 30 x 1000 / 680= 44 seconds ( approx)

"CM" and "mm" are SMALLER MEASUREMENTS than m. EXPLANATION:Conversion factor of m to cm and mm are 10^2 and 10^3 .

Smash the thanks button and MARK as braniliestExplanation:How do you FIND the specific heat of a solid? Specific Heat 1.For a mass m = gm = kg. 2.with specific heat c = cal/gm°C = joule/gm°C, 3.initial temperature Ti = °C = K = °F. 4.and final temperature TF = °C = K = °F, 5.Q = CALORIES = kcal = x 10^ calories. 6.Q = joules = x 10^ joules.

tion:LAW of Inertia it's also called Newton's first law of MOTION simply stated it means an object in motiontends to stay in motion or an object at rest tends to stay at rest unless the object is acted UPON by an UNBALANCED force.

th of slit is 0.2 mm.Explanation:=> The DISTANCE between the first and third minima in diffraction PATTERN, x:x = x₂ - x₁ = 3 mm= 3 * 10⁻³ m=> The distance of a SCREEN from a single slit,  D:D = 50 cm = 0.5 mWavelength λ = 6000A° = 6000 * 10⁻¹⁰ m=> Now, x = λD/dx₂ - x₁ =(3λ - λ)D/dx₂ - x₁ = 2λD/dd = 2λD / x₂ - x₁d = 2*6000*10⁻¹⁰*0.5/3*10⁻³d = 2 * 10⁻⁴ md = 0.2 mmThus, the width of slit is 0.2 mm.Learn more: Q:1 Screen is placed 80 cm from a single slit, which is illuminated with 5600 A light.

The main scale and Vernier scale are divided into small divisions though of DIFFERENT MAGNITUDES. The main scale is graduated in cm and mm. It has two fixed jaws, A and C, projected at right ANGLES to the scale. The SLIDING Vernier scale has jaws (B, D) projecting at right angles to it and also the main scale and a metallic strip (N). The zero of main scale and Vernier scale coincide when the jaws are made to touch each other. The jaws and metallic strip are designed to measure the distance/ diameter of objects. Knob P is used to slide the vernier scale on the main scale. Screw S is used to fix the vernier scale at a DESIRED position. 2. The least count of a common scale is 1mm. It is difficult to further subdivide it to improve the least count of the scale. A vernier scale enables this to be achieved.

by this you can UNDERSTAND..

Elevators or lifts follow netwon's second LAW of motion according to which the tension in ROPE is determined to limit the accelaration.Wheels and levers follow Newton's third law of motion as reaction force is the DRIVING MECHANISM for these two GADGETS

Rayleigh scattering of sunlight in Earth's atmosphere causes diffuse sky radiation, which is the reason for the blue color of the daytime and twilight sky, as well as the yellowish to reddish HUE of the low SUN. Sunlight is also SUBJECT to Raman scattering, which changes the rotational state of the molecules and gives rise to polarizationeffects.Scattering by particles similar to, or larger than, the wavelength of light is typically treated by the MIE theory, the discrete dipole approximation and other computational techniques. Rayleigh scattering applies to particles that are small with respect to wavelengths of light, and that are optically "soft" (i.e., with a refractive index close to Anomalous DIFFRACTION theory applies to optically soft but larger particles.Explanation:Here's ur answer.....hope it will help you.....please mark it as brainliest answer....

nitial velocity= 80 km/h = 22.2 m/s v= final velocity = 60 km/h = 16.7 m/s t= time = 5 s a= acceleration = ? a=v-u/t a= 16.7-22.2/5 a= -5.5/5 Therefore, a=-1.1 2.The TRAIN started from a railway station, so initial velocity of train, u = 0 Final velocity of train, v = 40 kmph  Final velocity, v = 40 × 5/18 = 11.11 m/s Assuming uniform acceleration of ‘a’ m/second square Time taken by train to get it's final velocity, t = 10 minutes = 600 seconds Using first equation of motion, V = u + at 11.11 = 0 + a×600 a = 11.11/600 = 0.0185 m/second square. So, required acceleration , a = 0.0185 3.Average speed=total DISTANCE/total time d=distance travelled at 30m/s and distance travelled at 40m/s … same distance time=distance/speed time at 30m/s =d/30 time at 40 m/s=d/40 total time=d/30 + d/40= 7d/120 average speed= (d+d)/(7d/120)= 240/7=34.2857 m/s It is not the average of the speeds because he spends more time at 30 m/s then at 40 m/s4.Distance covered in half an hour at 30km/hr = s×t = 30×1/2=15km.Distance COVETED in 1hr at 25km/hr= s×t= 25×1 =25km.Distance covered in 2 hrs at 40km/hr=s×t= 40×2=80kmTherefore, total distance covered= 15+25+80=120kmTotal time taken= 3HRS and 30 mins=7/2 hrs.Therefore, average speed=total distance covered/total time taken = 120×2/7 = 34.28km/hr5.

An AC motor is an electric motor DRIVEN by an alternating CURRENT (AC). The AC motor commonly consists of two basic parts, an OUTSIDE stator having coils supplied with alternating current to PRODUCE a rotating magnetic field, and an inside rotor attached to the output shaft producing a SECOND rotating magnetic field.

Friction is a force that HOLDS BACK the MOVEMENT of a SLIDING OBJECT

Electrical FLUX has SI units of VOLT meters (V m), or, equivalently, newton meters squared per coulomb (N m2 C−1). Thus, the SI base units of electric flux are kg·m3·s−3·A−1. Its DIMENSIONAL formula is [L3MT−3I−1].

directly proportional to each otherExplanation: the LARGER the AMPLITUDE the GREATER the sound(pitch)

ANCHE BREAKDOWN: It TAKES place in thicker junction. In this mechanism, when electric field existing in the depletion layer is sufficiently high the velocity of the carriers (minority carriers) colloid with the crystal atoms, THUS creating electron-hole pairs. As, pair of electron-hole is created in the midest of high field, they quickly separate and attain high velocity to cause further pair generation. So, that chain of collisions can give rise to an almost infinite current with very slight additional increase in voltage . This process is known as AVALANCHE BREAKDOWN .2) ZENER BREAKDOWN:It takes place in very thin junction.With small applied reverse voltage, it becomes possible for electrons to JUMP across barrier from valence band. In P material to some of the unfilled conduction band n material. This process is known as ZENER BREAKDOWN.

ny surface reflect back the heat to FOOD stuff wrapped in itExplanation:Aluminum is a metal which have malleable property so can be CONVERTED into thin sheets, ALUMINIUM is also a good conductor of heat but aluminum foil is used to wrap the food stuff and also kept at high temperature quite long because its shiny surface reflect back all the absorbed by the food to food itself and not conduct heat through the atmospherealuminum foil is also CHEMICALLY less reactive to the food so can be used without any harmTo know more about CONDUCTIVITY, visit:Thermal conductivity of aluminium with temperature brainly.in/question/10112301
