The weight of an object is an example of_______
(a) a discrete random variableย
(b) either a discrete or continuous random variable, depending on the weight of the object
(c) a continuous random variable
(d)ย either a discrete or continuous random variable, depending on the units of measurement
In the following questions, assume that all variable expressed inquantitative error format are uncorrelated measurements.
1-Calculate W=x+y, and express answer in standard format.
x = 13.1 +/- 0.8 cm
y = 12.0 +/- 0.5 cm
2-Calculate W=x-y, and express answer in standard format.
x = (3.0 +/- 0.2) x 10^-4 kg m/s
y = (1.5 +/- 0.6) x 10^-6 kg m/s
A student measured the force F between two coils as a functionof separation distance, x the results of the measurement are shownin the table below.g (m) 0.02 0.04 0.06 0.08 0.10F (N) 2.22 1.08 0.79 0.67 0.61The dependence of the force on the separation distance is known tobe F=a+ bx ^-3/2. Plot a straight line graph of the appropriatevariables, and use it to find values for a and b. be sure toinclude the units of the two parameters.please show steps,thank you
