instead of posting stupid quaotes on this ..y didnt some one put an answer..

can some one please give me an answer... I am in need of an answer, we have all the relevant points ..

it easier to push the door and open it if we use the door knob.. because the hinge is the axis upopn which the rotation occurs. using the door knob we can apply force easier and get higher acceleration.. and Newtons second law of rotational motion is external torque net = moment of inertia...

on the seesaw we sit on the edge and that is because equal amount of torque net force acts on each individual. i studied the troque but I am not sure what they are askin on my question about the door., it wil help me out if you can answer the question and i will try to understand it

yes i have studied torque.. but still I am not sure what the question is really askin.. can u please eloborate or give me some hints atleast thnksss

the physics of a swinging door ! Homework Statement why is it that its easier to open a swing door by pushing on the open side rather than the hinge side Homework Equations no equations The Attempt at a Solution a swing door has no latch so thus maybe its to do with force or...

if the difference is 4 hertz that means the unknown frequency will be 362 hertz because the formula is freq of beat = f2 - f1 thus difference of 4 hertz means 362- 358 is this correct please give me more hints I am stuck here

Ouabache= the relation is when two similar frequencies are heard= a beat is generated and freq of beat= freq1 -freq 2 therefore... my textbook doesn't have any sample questions that's y please help me with more direct answer.. or atleast one or two steps one attempt i made was let...

Finding unknown frequency from beats? Homework Statement i have to find the unknown resonant frequency of a tuning fork?? Homework Equations when this unknown is struck along a known freq of 360 hertz = you hear beat frequency of 2 hertz.. and when its struck alongside a known freq of...

thank you nasu heaps.. i completely understood your answer properly and thank you to godtripp aswell.. the question asked "DESCRIBE THE TRANSFORMATION OF THE ENERGY THAT OCCURS WHEN THESE PENDULAS are oscillated?? should i wirte about how the gravitational energy transforms to kinetic energy...

What hits the ground first?? Homework Statement If we simultaneously throw two tennis balls horizontally from the top of a building, one at 10 m/s and the other at 14 m/s. Neglecting the air resistance, which one will hit the ground first? Homework Equations i don't think we use...

The relevant equation will be okay the equation for velocity velocity= distance / time we have been given the distance which is 20 m, and were trying to find time , ??

Ezy velocity questions! Please help me // I am desperate! Homework Statement a)How long does it take an object to fall from a height of 20 m to reach the ground? b)if an object is launched horizontally from a height of 20 m with a velocity of 2/m/s where will it hit the ground...

thank you for that

im sorry which one is extension i used one forumula and i got 50 it was Final lenght= a Lenghts (final temp -initial temp) + initial lenght thus final length = 2.0 m (initial lenght) *( 45 deg-20 deg) + 2.0 m = 50 meters is this right approach ?
