Hey guys 10 points on what factor do the resistance of a conductor depend? |
|
Answer» Answer: The RESISTANCE of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to NOTE that electrical conductivity and resistivity are inversely proportional, meaning that the more CONDUCTIVE something is the less RESISTIVE it is. |

If the buoyant force of a liquid acting on an object placed in it is greater than the gravitational force acting on it , the object will floats on the liquid .? Is this statement is true |
|
Answer» Answer: buoyant force: An upward force exerted by a fluid that opposes the weight of an immersed object. When an object is immersed in a fluid, the upward force on the bottom of an object is greater than the downward force on the TOP of the object. The result is a net upward force (a buoyant force) on any object in any fluid. If the buoyant force is greater than the object’s weight, the object will rise to the surface and float. If the buoyant force is less than the object’s weight, the object will sink. If the buoyant force equals the object’s weight, the object will remain suspended at that depth. The buoyant force is always present in a fluid, whether an object floats, sinks or REMAINS suspended. The buoyant force is a result of pressure exerted by the fluid. The fluid pushes on all sides of an immersed object, but as pressure increases with depth, the PUSH is stronger on the bottom surface of the object than in the top Explanation: please support my answer and MAKE me brainliest |

A quantity has a value of-6.0m/s.it may be the? |
|
Answer» Answer: This quantity is the velocity of the OBJECT. Explanation: The units of the quantity suggest that either it is the speed or velocity of an object. SINCE speed is a scalar quantity and a scalar quantity is never negative , this must be the velocity. Velocity is vector quantity which requires direction along with magnitude so it can be negative. As per general rule OBJECTS travelling towards right have a positive velocity and those MOVING towards LEFT have negative velocity. |
