Force F acts on a block A and produces an acceleration 23 / m s . When the same force acts on block B, it produces an acceleration of 26 / m s . If the two blocks were tied together into a large block, what would be the magnitude of the acceleration of the combined block if the same force F acted on it? (Assume no other forces act on the blocks.) |

Answer» In physics, potential ENERGY is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.Electric potential energy, or ELECTROSTATIC potential energy, is a potential energy (MEASURED in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system. An object may have electric potential energy by virtue of two key elements: its own electric charge and its relative position to other electrically charged objects.The term "electric potential energy" is used to describe the potential energy in systems with time-variant electric fields, while the term "electrostatic potential energy" is used to describe the potential energy in systems with time-invariant electric fields.The SI unit of electric potential energy is joule (named after the English physicist James Prescott Joule). In the CGS system the erg is the unit of energy, being equal to 10−7 J. Also electronvolts may be used, 1 eV = 1.602×10−19 J.Mark as brainiest...❤Thank my answers...❤.Follow me for verified answers...❤...God bless u❤...May god give us a good knowledge...❤ |

Answer» By moving the convex LENS to and FRO along the scale, focus a DISTANT object on wall. The image which forms on the wall is very near to the focus of the lens and the distance of the lens from the image is read DIRECTLY by the metre scale. This gives the approximate focal LENGTH of the lens. |

A bus travels the first one third distance at a speed of ,10ms the next one third distance at 20ms and remaining one-third at 40 ms. The average speed of the bus for the whole journey is: |
|
Answer» Explanation:Bus travels first one third distance at a speed of 10 m/sThe next one third it travels at a speed of 20 m/sThe last one third at a speed of 40 m/sAverage speed for the whole journey➛ First we have to find the total distance covered by the bus➛ Let the bus travel x m in each of the three cases➛ Total distance travelled = x + x + x Total distance travelled = 3X m➛ Now we have to find the time taken in each of the three cases.➛ We know that, Time = Distance/Speed➛ In the first case, Time = x/10 s➛ In the second case, Time = x/20 s➛ In the third case, Time = x/40 s➛ HENCE, Total time taken = x/10 + x/20 + x/40 Total time taken = 4x/40 + 2x/40 + x/40 Total time taken = 7x/40 s➛ Now average speed of the bus is GIVEN by, Average speed = Total distance travelled/Total time taken Average speed = 3x ÷ 7x/40 Average speed = 3 × 40/7 Average speed = 17.14 m/s➛ Hence average speed of the bus is 17.14 m/s. |

If we take 50 g of water and supply 300 calorie of heat to it then what will be the rise in itstemperature? (take specific heat of water as 1cal g-1 °C-1). Assume no loss of heat insurroundings and all supplied heat getabsorbed by water only |
|
Answer» yesExplanation:Heat is a conserved quantity. Suppose two BODIES A and B are at different temperatures, wherein A is HIGHER and B is lower. When they are brought in contact, the heat given by A is equal to the heat gained by B. Thus, the heat is conserved in the SYSTEM.Here, we have ignored the heat EXCHANGED with the surroundings. If we consider the surroundings, the heat of the system will be conserved. |
