an object of mass 10g is sliding with a constant velocity of 10m/s on frictionless horizantal table.find the force required to keep the object moving with same velocity |
|
Answer» From newton's Ist law of motion, since there is no external force acting on the object it will remain in its ORIGINAL state of motion. Hence, ZERO force is required to keep the object moving with CONSTANT velocity, So the correct answer is 0NI HOPE IT WILL HELP U PLZZZZ FOLLOW ME AND SAY THX TO MY ANSWERPLZZZZZ FOLLLOW ME GUYS ......... |

Why do conductors offer resistance? |
|
Answer» Due to these FREE electrons, current flows through the conductor when a potential difference is APPLIED across the conductor. ... Due to this, a RESISTANCE is offered to the motion of electrons FLOW due to increased number of collisions. Flow of electrons is NOTHING but current. |

1 F. State whether the following statementsare true or false. If false, rewrite thecorrect form of statements.1. The SI unit of force is newton. 2. The moment of a force increases ondecreasing the perpendicular distancebetween force and axis of rotation. 3. We prefer to use a long spanner to loosena tight nut.4. Steering wheel of a car is used toaccelerate the car.5. Pressure is exerted by solids and liquids butnot by gases.6. Pillars of bridges have broad bases so as toreduce pressure on the ground.7. A camel can walk easily on a sandy surfacebecause it has long legs.8. Water in a tank exerts pressure only on itsbottom.9. Atmospheric pressure decreases with anincrease in height from the ground.10. The numerical value of atmosphericpressure is about 105 pascal.11. Gases exert pressure in all directions.12. It is easier to hammer a sharply pointednail into a wooden piece than a blunt nail.13. Liquid pressure does not depend on its density.14. We prefer a school bag having broadstraps so as to reduce pressure on ourshoulders.who give correct answer i will mark as branliest answer. |

Intially an object is moving with acceleration along z- direction.If force is applied along X- direction,what change is produced in the acceleration? Justify. |
|
Answer» Acceleration (a) is the change in velocity (Δv) over the change in TIME (Δt), represented by the equation a = Δv/Δt. This ALLOWS you to measure how fast velocity CHANGES in meters PER second squared (m/s^2). |

If electrons in the matal wire causes resistance Then why is resistance inversely proptional to cross sectional area of wire? Because in my opinion as the area increases atoms increase then electrons increases It implies resistance should also increase Isn't it? |
|
Answer» Explanation:- Resistance is DIRECTLY PROPORTIONAL to the length of the wire, and inversely proportional to the CROSS sectional AREA of the wire. ... As a wire gets longer its resistance increases, and as it gets thinner its resistance ALSO increases because its cross sectional area decreases. |

Derive the formula for asseleration and tension in case of atwood's machine |
|
Answer» Equal masses, no accelerationFor the system to be in equilibrium, T = Fg. The net FORCE is 2Fg - 2T = 0, so there is no acceleration. The tension in the STRING is 2T or 2Fg. The string supports both masses, so we would expect the tension in this CASE to be the sum of the two downward forces |
