A small block B rests over a long block A of length L as shown figure. They aregiven sharp impulse such that they acquires speed u and v(u > v) The time takenby the block B to drop down is |
|
Answer» Answer: As there are no external forces acting on the 'A + B' system, its total momentum is conserved. If the MASSES of A and B are 2m and 2 respectively, and v is the final common velocity, MU=(m+2m)v or v=u/3 Work done against friction = loss in KE = 2 1 mu 2 − 2 1 (3m)v 2
= 2 1 mu 2 − 2 1 (3m) 9 u 2
= 2 1 mu 2 [1− 3 1 ]= 3 2 × 2 1 mu 2
The FORCE of friction between the blocks is μmg. Acceleration of A (to the right) =a 1 = 2m μmg = 2 μg
Acceleration of B (to the left) =a 2 = m μmg =μg Acceleration of A relative to B =a 1 −(−a 2 )= 2 3 μg. |

C) Ether'sObject (or Image can be2 Rea- Wal |
|
Answer» Answer: 1) Ether, any of a class of organic compounds characterized by an oxygen atom BONDED to two alkyl or aryl groups. Ethers are similar in structure to alcohols, and both ethers and alcohols are similar in structure to water. In an alcohol one hydrogen atom of a water MOLECULE is replaced by an alkyl group, whereas in an ether both hydrogen atoms are replaced by alkyl or aryl groups. Ethers are also important in MEDICINE and pharmacology, especially for use as anesthetics. For example, ethyl ether (CH3CH2―O―CH2CH3), simply known as ether, was first used as a surgical anesthetic in 1842. sorry I don't understand second name.

A body travels from A to B with a velocity of 90 km/h and return to A with a velocity of 60 km/h . What isthe average velocity and average speed? |
|
Answer» AVERAGE SPEED=> Initial speed from a to b = 60km/h DISTANCE = 60kms. Final speed form b to a = 90km/h Distance = 90kms. ➡Average speed = Total distance / total time taken ➡Average speed = 60 +90 /1 + 1 ➡Average speed = 60 + 90 / 2 ➡Average speed = 150 / 2 ➡Average speed = 75km/h. AVERAGE VELOCITY Initial velocity (U) = 60km/h Final velocity (v) = 90km/h ➡Average velocity = v + u / 2 ➡Average velocity = 90 + 60 / 2 ➡Average velocity = 150 / 2 ➡Average velocity = 75km/h please mark me brain mark list |

A car mounted on shock absorbers is like a mass on a spring. If we ignore damping, how will the frequency of the oscillations change if passengers (or heavy load) are added to the car? |
|
Answer» FIRST, the chassis isn’t mounted on SHOCK absorbers. The chassis is mounted on springs. Shocks are used to control the oscillation of the spring. The stiffer the shock the more control of the oscillation. Now to the other part of your QUESTION, the oscillation will change according to the weight of the vehicle. The question is how much weight or how little weight will AFFECT the ride. The heavier the load the lower the vehicle will sit, the lower the vehicle sits the harder the ride. please mark me brain mark list |

Light wave produced by oscillating charge consists of a periodic vibration of (MCQ - CHOOSE ONE) Electric field Magnetic field Either of them Both of them |
|
Answer» Answer: Key Points Maxwell’s FOUR equations describe how electric charges and currents create electric and magnetic fields, and how they affect each other. Gauss’s law relates an electric field to the charge(s) that create(s) it. Gauss’s law for magnetism states that there are no “magnetic charges” analogous to electric charges, and that magnetic fields are instead generated by magnetic dipoles. Faraday’s law describes how a time-varying magnetic field (or FLUX ) induces an electric field. The principle behind this phenomenon is used in many electric generators. Ampere ‘s law originally stated that a magnetic field is CREATED by an electrical current. Maxwell added that a changing electric flux can also generate a magnetic field. Key Terms differential equation: An equation involving the derivatives of a function. flux: A quantitative description of the transfer of a GIVEN vector quantity through a surface. In this context, we refer to the electric flux and magnetic flux. |

Choose the appropriate items from the followingNichrome, Tungsten, Fuse Wire, Nitrogen a. Which is used as a heating coil ? b. Which is an alloy of tin and lead? c. Which is used as filament ? |
|
Answer» Answer: c) is there correct answer Explanation: Hint: We solve this problem by using the formula of simple interest. The formula for the simple interest is given as SI=P×T×R100 Where P is the principal amount, T is the TIME period and R is the rate of interest per annum. After finding the simple interest for all years from 1 to 6 we create a table of ordered pairs containing the number of years as x coordinate and simple interest as y co – ordinate so that we can plot them on a graph of a certain scale. Complete step by step answer: We are given that the principal amount as ⇒P=8000 We are also given that the rate of interest per annum as ⇒R=5 Let us assume that the time period as T We know that the formula for the simple interest is given as SI=P×T×R100 Where, P is the principal amount, T is the time period and R is the rate of interest per annum. By using the above formula we get the simple interest in terms of time period as ⇒SI=8000×5×T100⇒SI=400T Now, let us TAKE the time period as 1 year then we get the simple interest of 1 year as ⇒SI1=400×1⇒SI1=400 Now, let us take the time period as 2 years then we get the simple interest for 2 years as ⇒SI2=400×2⇒SI2=800 Now, let us take the time period as 3 years then we get the simple interest for 3 years as ⇒SI3=400×3⇒SI3=1200 Now, let us take the time period as 4 years then we get the simple interest for 4 years as ⇒SI4=400×4⇒SI4=1600 Now, let us take the time period as 5 years then we get the simple interest for 5 years as ⇒SI5=400×5⇒SI5=2000 Now, let us take the time period as 2 years then we get the simple interest for 2 years as ⇒SI6=400×6⇒SI6=2400 Now, let us create a table containing the order pairs containing number of years as x co – ordinate and simple interest as y co – ordinate as follows Time period (T) Simple interest (SIi) Ordered pair(T,SIi) 1 400 (1,400) 2 800 (2,800) 3 1200 (3,1200) 4 1600 (4,1600) 5 2000 (5,2000) 6 2400 (6,2400) Now, let us consider a scale of the required graph as follows On X – axis 1 unit equal to 1 year On Y – axis 1 unit equal to RS. 400 By using the above scale and the coordinate of points in the table we get the graph as Note: Students may make mistakes in finding the simple interest of 2, 3, 4, …, 6 years. By using the simple interest formula for 2 years we get ⇒SI2=8000×5×2100⇒SI2=800 But students may make mistakes in taking the principal value for the time period of 2 years. The amount after the 1 year is given as ⇒A=8000+400=8400 |
