|
Answer» HEY there is ANSWER !!! I hope you help !!! mark me brainlist !!! ======================== The windings (coils of wire) on thearmature are CONNECTED to the commutator segments. COMMUTATORS are used in direct current (DC)machines: DYNAMOS (DC generators) and many DC motors as well as universal motors. In a motor the commutator applies electric current to the windings. |

Are internal energy and heat energy the same explain why |
|
Answer» No internal energy and heat energy are not the same but their units are same. Internal energy can come HROM chemical energy, physical energy and also biochemical process but heat energy only is the SUM total of kinetic and potential energy of all the molecules of a substance. Though they differ in many ways but their units are same. They are MEASURED in Joules. |

A ring of radius r carriges a charge Q uniformly distributed over its length. A charge q placed at its centre will experience a force is equal to |
|
Answer» let POINT of INTERSECTION of ring & sphere are P,Q ...let center of ring is O & center of sphere is O1 ... OO1 bisects PQ in two equal parts , if S is the point of intersection of OO1 & PQ then in triangle right angled POS PO = R , OS = R/2 so angle POS = @ using trigonometry , [email protected] = OS/PS = 1/2 @ = pi/3 total angle substended by arc is 2pi/3...this is the arc of ring which lies inside sphere & substends 2pi/3 angle at the center of ring... for 2pi radian CHARGE = q for unit radian = q/2pi for 2pi/3 radian q1 = (q/2pi)(2pi/3) = q/3 total flux through sphere = total charge enclosed/ebsilen = q/3ebsilen this is the required flux |

Relation between apparent activation energy and true activation energy |
|
Answer» Answer: Activation energy, in chemistry, the minimum amount of energy that is required to activate ATOMS or molecules to a condition in which they can undergo chemical transformation or physical transport. In transition-state theory, the activation energy is the difference in energy content between atoms or molecules in an activated or transition-state configuration and the CORRESPONDING atoms and molecules in their initial configuration. The activation energy is usually represented by the symbol Ea in mathematical expressions for such QUANTITIES as the reaction rate constant, K = Aexp(−Ea/RT), and the diffusion coefficient, D = Doexp(−Ea/RT). plzz mark as brainliest |

a carnot engine has an efficiency of 50% when its sink temperature is 27°c what must be the change in its source temperature for increasing its efficiency to 60%? |
|
Answer» TAKING the Sink Temperature(T2) = 27 degree celsius = 300 kelvin Efficiency(eta) be 25% = .25 Source Temperature(T1) = ? Efficiency= (T1 - T2) / T1 Efficiency= 1 -T2/T1 T2/T1 = 1 - Efficiency T1 = T2/(1 - Efficiency) T1= 300/(1-.25) T1 = 400 kelvin = 127 degree celsius |

two cars A and B are moving in same direction with velocities 30m/s and 20m/s . when car A is at a distance 'd ' behind the car B , the driver of car A applies brakes producing uniform retardation of 2m/s2. there will be no collision when ? |
|
Answer» For no COLLISION the velocity of A MUST reduce to that of velocity of B. VA = 30 m/s , VB = 20 m/s , a = - 2 m/s2 i.e. the relative final velocity of A with respect to B must be 0. Vr = 0 The relative initial velocity of A with respect to B is ( VA-VB ) The relative ACCELERATION of A with respect to B is (-a - 0 ) = - a Using the equation : V2= u2+ 2as 0 = ( VA-VB )2 + 2 × -a × s' s' = ( VA-VB )2 / 2 a = (30-20) 2 / 4 =25 m
Hence no collision OCCURS when d is greater than 25 m |

Why there is no such a point between two electric charges where the electric intensity be 0? |
|
Answer» YES, there is such a point. Electric field is ZERO in that point because the SUM of electric field VECTORS have same intensity and direction, but are opposite. That point is halfway between two like charges. Also known as a dead spot. |
|
| 33. |
Why there is no zero-field point for a pair of equal-magnitude-but-opposite-sign charges? |
|
Answer» Answer: There is no zero-field POINT for a pair of equal-magnitude-but-opposite-sign CHARGES. Electric field is zero in that point because the sum of electric field vectors have same intensity and DIRECTION, but are opposite. That point is HALFWAY between two like charges. |

Why is electric current taken oppostite to the flow of electrons when its made up of electron??? |
|
Answer» This is because electric current always FLOWS from positive terminal to NEGATIVE terminal...... |
|

Why an electric cell has a positive terminal and a negative terminal ? |
|
Answer» Answer: Since the current is the flow of positive CHARGE, the NEGATIVE ELECTRONS flow in the opposite direction to this (conventional) current. Within the cell itself, the charge flows from the negative TERMINAL to the positive terminal as it gains electrical energy. please support me yarr and MARK as Brainliiests |
