if you know the weight of a brick to be 25 N.
Describe how you could use a meter stick and a pivot to measure the weight of a baseball ?
Homework Answers
now since we know the weight of a brick i.e 25 N.
we can measure the weight of a baseball using a meter stick and a pivot.
place the meter stick on the pivot such that it balances out ,
place the brick on one side of the balanced stick and baseball on the other side.
check carefully which side lowers down . the side that lowers down has more weight than the other.
eg : if baseball lowers down means it is heavier than the brick.
so what we do is we start adding weight to the upper side that is to the side where brick is placed untill the balance becomes balanced.
now when the pivot or the balance is balanced we can count the weight as --- the weight of brick +(the amount of weight added) = total weight of baseball

You have determined all the torques on the meter stick around point O, and you know all forces except the force that the nail (axis) exerts on the meter stick. Use the condition for translational equilibrium (the vector sum of the forces - 0) to determine this force by finding both the component along the stick and the one perpendicular to the stick. Calculate also the magnitude of this force (square-root of the sum of the squares) and the angle...

Let's consider a variation of Experiment 2 where in- stead of the system being balanced by hanging a mass on the stick, we have the system lean against a frictionless wall (at a 30° angle relative to the hor- izontal), like a ladder except supported vertically and horizontally by an axle rather than the floor. To begin analyzing this system, label the perpendic- ular distance from the axis of rotation (chosen as the pivot point for simplicity) to the...

Identify at least one likely source of random errors and at least one likely source of systematic errors. How would you reduce these errors? a. You need to measure 10 meters. You don't have a tape measure, so 2. you use a meter stick to measure the distance You need to measure the weight of a penny, but you only have a postage scale b.

You have a new Digital Multimeter and would like to know its input impedance. You have three different pairs of resistors with values of 600, 60k and 6M. You construct a voltage divider from each pair, power it with 20V DC and use the new meter to measure the output voltage. For R=600, you measure 10V. For R=60k, you measure 9.95V. For R=6M, you measure 6.66V. What is the input impedance of your new meter?

I know how to do these and I know that the N is Nsp2 - Csp2 but
I do not understand why the N is Nsp2 and not Nsp3 since there are
technically 4 domains? I would assume that it would be Nsp3 with
the amount of domains but I have noticed the trend of it being
Nsp2, what is the reasoning for this? Thank you!!!
