. if A = i + 2 j + 3 k and B = − i + $ j + 5 k are perpendicular to each other then find value of $ Also find unit vector along B. |
|
Answer» Answer: Unit vector is just a vector of length I Unit vector in the DIRECTION of any vector can be calculated just by dividing the vector with its magnitude. Unit vector perpendicular to two given vectors can be found by dividing the cross product of two vectors with its magnitude. i.e, Unit vector perpendicular to A & B is given byC^ = ∣ A × B ∣( A × B) Where A = i^ −2 j^ + k^ × B =3 i^ − j^ +2 k^⇒ C=( i^ −2 j^ + k^ )(3 i^ − j^ +2 k^ )=(− k^ −2 j^ +6 k^ −4 i^ +3 j^ + i^ )C =(−3 i^ + j^ +5 k^ )∣ C ∣= 9+1+25 ∣ C ∣= 35 C^ = ∣ C ∣C = 35 (−3 i^ + j^ +5 k^ ) Explanation: Please MARK as BRAINLIEST answer and follow me please and thank me please Because I am a very good boy |

Answer» Explanation: UNIFORM Motion. A body is said to be in uniform motion if it TRAVELS equal distances in equal intervals of time, no matter how small these time intervals may be. Oscillatory motion is defined as the to and fro motion of an OBJECT from its mean POSITION. Translatory motion means motion of an object in which all the particle move through the same distance with same time. Translatory motion are of TWO types : 1)Rectilinear motion : |

Answer» Answer: current: I = Q/t, Where I = Current Q = NET charge flowing. t = time • Unit: The unit of current is Ampere. Q = COULOMB(C) I = Ampere(A) t = Second(s) 1 A = 1C/1s Potential Difference: The potential difference between two separate points is defined as the work done to move a unit positive charge from one point to another. V = W/Q • Unit: The unit of potential difference is Volt 1 Volt = 1 Joule/ 1 Coulomb Ohm’s Law: Current ∝ potential difference V ∝ I V = I R where, R = Resistance • Unit: R = Ω(Ohm) 1Ω = 1V / 1 A • Factors on which resistance depends: ○ R ∝ 1, when A and material constant l = length ○ R ∝ 1/ A, when l and material constant A = perpendicular cross-section R ∝l / A, R = ρl / A, where ρ = resistivity • Resistivity: Resistivity of a substance is equal to the resistance of a unit square of that substance. Its Unitis Ωm. Resistance in a series connection: R = R1 + R2 + R3 + … + RN
Resistance in parallel:
Heating Effect of current: Electric energy = VIt Heat, H = VIt = I2Rt • Application: Electric iron, toaster, fused wire, etc. Fused wire: a low-melting point wire connected in series with electric devices for safety. Electric power: P = VI = I2R = V2/ R • Unit: 1 kWh = 3.6 × 106J 1 W = 1V × 1A Ohm’ law: Under constant physical conditions (i.e., constant temperature, pressure etc.), the current flowing through a conductor is directly proportional to the potential difference across the conductor. Potential difference (which is measured in Voltage) is the cause of current (which is measured in Ampere). In conductors, flow of electrons constitute current. In a circuit current flow from positive terminal of the battery to the NEGATIVE terminal, but electrons travels from negative terminal to the positive terminal. The negative terminal of a battery is said to be at lower potential and the positive terminal is said to be at higher potential. When a battery is not connected to any circuit, the potential difference across the terminals of the battery is equal to the EMF of the battery. (EMF = Electro Motive Force). Electromotive force, also called EMF, (denoted and measured in volts), REFERS to voltage generated by a battery or by the magnetic forceaccording to Faraday's Law, which states that a time varying magnetic field will induce an electric current. |

Nichrome is note used as filament incandensent whyglows brightlyit emit white light |
|
Answer» Answer: nichrome is NOTE used as filament incandensent why glows brightly it emit white light Explanation: Nichrome wire, an alloy of nickel and chromium, and often iron (or other elements) is good for making heaters but not lamps. At rated voltages, nichrome will glow orange-red, not the bright white that is needed for illumination. If you increase the voltage to get a brighter color, the nichrome will burn open (melt.) The CHALLENGE in designing lamp filaments is finding a material that gives a bright glow but does not burn open. Take a look at the glow inside your toaster. It’s not very bright. It might be good for mood lighting. Edison worked for many years to find a material that WOULD glow brightly and not burn open. There are a lot of people who think that Thomas Edison INVENTED the electric light bulb. That’s not accurate. Edison invented the LONG LASTING electric light that was commercially feasible. Edison and his staff experimented with thousands of materials, including oddities such as CARBONIZED human hair and carbonized sewing thread before getting good results with bamboo and later with a tungsten alloy recipe. One of the other challenges was to create a means to hold the material so that the filament would not be easily broken. When metals get hot, they get brittle. It’s interesting to note that nichrome is still around as a means of resistance heating. Incandescent lamps are being replaced by new lighting technologies such as LED-s, but toasters are still being made with nichrome filaments! |
