How does smell affect taste? Do different types of materials affect air resistance differently? 3. Why are the leads in electronic circuits very short?Ans: Resistance increases with the length of the wire. Water comes out faster in a shorter pipe than a longer one. Why do we wear rubber slippers and gloves when working with electricity?Ans: Rubber is an insulator and does not allow current to flow through it. Based on the level of opposition a material has for current through it, we classify them as conductors and insulators.

How Does Microwave Radiation Affect Different Organisms? In this science fair project, students find what type of material works best as a parachute. Do different colors of light work better than others? Why are superconductors kept at a very low temperature?Ans: Heat increases the resistance. Did you know that air has substance too? The resistance of solid conductor is inversely proportional to the the area of cross section. It means that it has a length of \({\rm{1}}\,{\rm{m}}\)and a cross-sectional area of \({\rm{1}}\,{{\rm{m}}^{\rm{2}}}\).Its unit is ohm-metre \((\Omega {\rm{m}})\)\({\rm{R = }}\frac{{{\rm{\rho l}}}}{{\rm{A}}}\)If \({\rm{l = 1}}\)and \({\rm{A = 1\;}}{{\rm{m}}^{\rm{2}}}\), then unit of resistivity is,\({\rm{\rho = }}\frac{{{\rm{RA}}}}{{\rm{l}}}{\rm{ = }}\frac{{{\rm{\Omega \times 1\;}}{{\rm{m}}^{\rm{2}}}}}{{{\rm{1\;m}}}}{\rm{ = \Omega m}}\)There is another term called conductivity. "text": "Rubber is an insulator and does not allow current to flow through it. Resistance is the opposition to the flow of charges in a conductor. Make an average of your data. So, the lead wires are made to be as short as possible." When printing this document, you may NOT modify it in any way. On the application of a little energy, the outermost or the loosely packed electrons of the valence band can easily reach the conduction band.

This greater force of gravity would have a direct effect upon the elephant's acceleration; thus, based on force alone, it might be thought that the 1000-kg baby elephant would accelerate faster. At this instant in time, the net force is 0 Newton; the object will stop accelerating. << - Brainly.in. The specific resistance of some materials are as below: Heat is due to the motion of atoms in a material. Do different types of materials affect air resistance differently? Test different sized parachutes to see how changes in the size of the parachute affect flight. },{ Examples are glass, rubber, plastic, wood. What happens to the resistance of a wire if its area is doubled and length is halved? Resistivity is a measure of how well a material resists (or opposes) current flowing through it. The size and shape of the conductive elements within a material also play a role in its resistance. ), Shape - try making parachutes of different shapes (circle, rectangle, triangle, etc. Categories . Lift. When objects falling to the ground are no longer accelerating but travelling at a constant velocity, the forces of air resistance and gravitational force are said to be balanced every material has a friction coefficient higher the friction coefficient higher friction it will experience by air. To answer this questions, Newton's second law will be applied to the motion of a falling skydiver. The faster an object is falling through air, the greater the air resistance. Get the clay.

When the distance between two places is more, we take a longer time to reach than in a shorter distance.2. For each case, use the diagrams to determine the net force and acceleration of the skydiver at each instant in time. Because of less electrical resistance a thicker wire carries more current with less voltage drop than a thinner wire. So air resistance is not a real force and is more like a collective term for the different forces that slow down an object (or act against the motive force/thrust) while traveling through air? In summary, the resistance of a material is determined by a combination of factors, including its chemical composition, the size and shape of its conductive elements, and the temperature at which it is operating. Use the hole puncher and punch every corner (that's 4) and tie a string through the holes on every corner. A car, for instance, has less air resistance moving forwards or backwards than it has moving (through the air) sideways. Tie one piece of string to each corner of the plastic square.
