Infinite wires, each carrying a current 0.5 A, are kept parallel to y-axis and intersecting x-axis at `x=+-1` m, `+02 m`, `+-4 m`, `+-8m` etc. Wires kept at positive values of x carry current in the same direction while wires kept at negative values of x carry current successively in opposite directions as shown in Fig. A wire is kept parallel to x-axis and intersecting y-axis at y=2 m. It carries a current i. Assuming this wire to be insulated from others then the current i in it such that magnetic induction at O is zero is (assuming each wire to be infinitely long)A. `8/3 A` along positive x-axisB. `4/3 A` along negative x-axisC. `5/3 A` along negative x-axisD. `7/3 A` along positive x-axis |
|
Answer» Correct Answer - A Given that wires kept at negative x value carry current successively in opposite directions. The field due to wire kept `x= +- 2m, +-8m` etc, cancel each other. Due to wires kept at `x= +-1m, +-4m,` Field are in upwards direction and net field is given by: `B=2xx(mu_(90)i)/(2 pi) (1+1/4+1/13 +....)` `implies B=(4 mu_(0)i)/(3 pi)=(2 mu_(0)i)/(3 pi) =(2mu_(0)i)/(3 pi) ("since" i=0.5A)` This field is negative by field due to wire placed at y=2m. This wire must carry current I along positive x-axis such that `(mu_(0)i)/(2 pi xx 2)=(2 mu_(0)i)/(3 pi)` Thus, `I=8/3 A` along +x-axis. |

|
Answer» Two years ago, I moved to a new neighbourhood. There seemed to be very few people in this area without telephones, so I expected to get a new phone quickly. I applied forone as soon as I moved into my new house. ‘We aren’t supplying a lot of new phones in your area’ , an engineer told me. ‘A few people want new phones at the moment and the company is employing fewer engineers than last year so as to save money. A new phone won’t cost you much money, but it will take a little time. We can’t do anything for you before December. ‘You need a lot of patience if you’re waiting for a new phone and you need many friends whose phones you can use as well. Fortunately, I had both. December came and went, but there was no sign of a phone. I went to the company’s local office to protest. ‘They told me I’d have a phone by December, ’ I protested. ‘Which year?’ the assistant asked. |

What are the advantage and disadvantage of friction? |
|
Answer» ADVANTAGES OF FRICTION Friction plays a vital role in our daily life. Without friction we are handicap. 1. It becomes difficult to walk on a slippery road due to low friction. When we move on the ice, it becomes difficult to walk due to low friction of ice. 2. We can not fix nail in the wood or wall if there is no friction. It is friction which holds the nail. 3. A horse can not pull a cart unless friction furnishes him a secure Foothold. 4. We can write on a paper or on a board. 5. Friction helps in applying the brakes. 6. It helps in walking on the floor. 7. Coffee mug stays on the dashboard 8. Shuffling across a carpet to shock someone 9. Dragging of atmosphere with earth is possible 10. Helps to pevents the life on earth by burning asteroids. DISADVANTAGES OF FRICTION Despite the fact that the friction is very important in our daily life, it also has some disadvantages like: 1. The main disadvantage of friction is that it produces heat in various parts of machines. In this way some useful energy is wasted as heat energy. 2. Due to friction, we have to exert more power in machines. 3. It opposes the motion. 4. Due to friction, noise is also produced in machines. 5. Due to friction, engines of automobiles consume more fuel which is a money loss. 6. Machine efficiency is decreased: energy input is lost to heat 7. Getting shocked by doorknobs 8. Rugburn 9. It counteracts movement and so it takes more energy to move, it can cause unwanted heat (e.g. in machine parts), and it wears things out like shoes. 10. Forest fires are caused due to friction between branches of trees |

If A = [(2, 5), (1, 3)],\(\begin{bmatrix}2&5\\1&3\end{bmatrix}\).find adj A. |
|
Answer» We have matrix A = \(\begin{bmatrix}2&5\\1&3\end{bmatrix}\). The minor of elements a11, a12, a21 and a22 of matrix A are M11 = 3, M12 = 1, M21 = 5 and M22 = 2, respectively. Cofactor of element a11 of matrix A is A11 = (-1)1+1M11 = 3 Cofactor of element a12 of matrix A is A12 = (-1)1+2M12 = -1 Cofactor of element a21 of matrix A is A21 = (-1)2+1M21 = -5 Cofactor of element a22 of matrix A is A22 = (-1)2+2M22 = 2. Therefore, the cofactor matrix of matrix A is \(\begin{bmatrix}3&-1\\-5&2\end{bmatrix}\) Therefore, the adjoint matrix of matrix A is adj A = \(\begin{bmatrix}3&-1\\-5&2\end{bmatrix}'\) = \(\begin{bmatrix}3&-5\\-1&2\end{bmatrix}\). Hence, if A = \(\begin{bmatrix}2&5\\1&3\end{bmatrix}\). Then, adj A = \(\begin{bmatrix}3&-5\\-1&2\end{bmatrix}\). |

By how much percent area is decreased if the radius of a circle is decreased by 30%? |
|
Answer» Let the radius of the circle is r. Therefore, the area of the circle is \(\pi\)r2. After decreasing 30% radius of the circle, The actual radius of the circle is r – \(\frac{30}{100}r\) = r – 0.3r = 0.7 r. The area of the circle after decreasing = \(\pi\)(0.7r)2 = 0.49 \(\pi r\) 2. Decreased area = Area of circle before decreasing – Area of circle after decreasing = \(\pi r\)2 – 0.49\(\pi r\)2 = 0.51 \(\pi r\)2 = 51% × Area of circle before decreasing. Hence, 51% area is decreased if the radius of a circle is decreased by 30% |

If [((x - y), 2y), ((2y + z), (x + y))] = [(1, 4), (9, 5)],\(\begin{bmatrix}x-y&2y\\2y + z&x + y\end{bmatrix}\) = \(\begin{bmatrix}1&4\\9&5\end{bmatrix}\).then write the value of (x + y + z). |
|
Answer» We have \(\begin{bmatrix}x-y&2y\\2y + z&x + y\end{bmatrix}\) = \(\begin{bmatrix}1&4\\9&5\end{bmatrix}\). We know that if two matrices are equal then their corresponding elements are also equal. Now, equating the corresponding elements of both matrices, we get 2y = 4 ⇒ y = 2. ... (1) (By equating a12 elements of both matrices.) x − y = 1 ⇒ x = 1 + y ⇒ x = 1 + 2 ⇒ x = 3. ... (2) (By equating a11 elements of both matrices and putting the value of y = 2 from equation (1).) 2y + z = 9 ⇒ z = 9 − 2y ⇒ z = 9 − 4 ⇒ z = 5. ... (3) (By equating a21 elements of both matrices and putting the value of y = 2 from equation (1).) x + y = 5 ⇒ 3 + 2 = 5 ⇒ 5 = 5 (Satisfying) (By putting x = 3 and y = 2 from equations (2) and (1), respectively) (By equating a22 elements of both matrices.) Therefore, x = 3, y = 2 and z = 5. Therefore, x + y + z = 3 + 2 + 5 = 10. Hence, if \(\begin{bmatrix}x-y&2y\\2y + z&x + y\end{bmatrix}\) = \(\begin{bmatrix}1&4\\9&5\end{bmatrix}\). Then, the value of (x + y + z) is 10. |

Electromagnetic waves. |
|
Answer» Electricity can be static, like the energy that can make your hair stand on end. Magnetism can also be static, as it is in a refrigerator magnet. A changing magnetic field will induce a changing electric field and vice-versa—the two are linked. These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. |

A wheel rotates for 5sec with a constant angular acceleration and describe a displacement of 100radian, it is then rotates with a constant angular velocity in the next 5sec and describe a displacement of of 80 radians. Find 1) initial angular velocity. Answer (24rad/s)2) final angular velocity (16rad/s)3) angular acceleration of the wheel(1.6rad/s²)Hint: simultaneous equation.Please I just need a clear explanation of the equations to use. |
|
Answer» As we know that the wheel rotate for 5 s with constant angular acceleration so we have θ \(=\frac{\omega+\omega_0}2t\) 100 \(=\frac{\omega+\omega_0}2(5)\) ω+ω0 = 40 now we know that after this it rotate with constant angular speed for t = 5 s so now we have θ = ωt 80 = ω(5) ω = 16 rad/s now we have 16+ω0 = 40 ω0 = 24 rad/s now angular acceleration is given as α \(=\frac{\omega+\omega_0}t\) α \(\frac{16-24}5\) α = -1.6 rad/s2 |
