Finding the median in a bar graph problem • Physics Forums i do not understand the language used in part a, otherwise i would indicate the number of children the women have in order as ##1,2,3,4,5## and ##6## now for part b) this is where i have a problem To find the median assumably for the number of children, we have to find the total number of
What is this part of a graph on the axis called? • Physics Forums On this graph on the Y-axis just above the origin is a "zigzag" mark (highlighted with the red circle) which represents a discontinuity as the value of Y jumps from 0 to 130 Does this mark have a formal name?
Difficult time with motion graphs dynamics - Physics Forums Homework Statement The figure below shows the speed of a person's body as he does a chin-up Assume the motion is vertical and the mass of the person's body is 72 7 kg Determine the force exerted by the chin-up bar on his body at the following times My answers: Homework Equations F = ma
EMF induced by a magnet falling through a coil - Physics Forums I've been told that if you drop a magnet through a coil the induced emf and flux graphs would look like this: I understand that when the bar magnet is in the middle of the coil the emf induced is zero as flux change in top and bottom is in opposite directions but why is effective flux maximum
Stress concentrations: find max d and min r on stepped bar The problem: The stepped bar with a circular hole, shown in Figure P5 75, is made of annealed 18-8 stainless steel The bar is 12-mm thick and will be subjected to an axial tensile load of P=70kN The normal stress in the bar is not to exceed 150 MPa To the nearest millimeter, determine (a)
Induced emf as a magnet passes through a solenoid I'm doing a lab write-up for physics 2 The experiment is about the title, a bar magnet being dropped through a solenoid I have to explain four graphs that plot the change in emf (y axis) vs time (x) axis There are incoming and outgoing peaks on these graphs I have to tie these results
Speed of a Magnet Falling through a Conducting Wire Homework Statement A small but very powerful bar magnet falls from rest under gravity through the center of a horizontal ring of conducting wire, as shown in the figure below (on the left) The speed-versus-time graph, in arbitrary units, of the magnet will correspond most closely to which of
Drop height of a magnet vs. induced EMF in a solenoid I am currently working on an experiment that involves dropping a magnet from varying heights and measuring how the induced emf of a solenoid changes as a result I am currently somewhat struggling with a derivation for a relationship between the two variables, however, this is what I have been
