The term "accuracy" best refers to which of the following?a. whether or not a measurement is correct
b. how "close together" a set of measurements is
c. whether or not a tool for making measurements is useful
d. how close a measurement is to an accepted value for the measurement

Answers

Answer 1
Answer:

Answer: d. how close a measurement is to an accepted value for the measurement

Explanation:

Accuracy can be define as the quality or state of some measurement being correct depending upon the measurement, specific conformations and calculations. It refers to the closeness of the measurement to a define specific or acceptable value. It is the degree of correctness of a particular value obtain after the measurement.    

Answer 2
Answer: D: how close a measurement is to an accepted value for the measurement.

How do you find an object's mass on an acceleration vs. force graph?

Answers

Newton's 2nd law of motion is:  Force= (mass) x (acceleration).

Divide each side by 'acceleration' and you have:  Mass = (force) / (acceleration).

-- At any point on the graph, read off the force and the acceleration.
-- Divide the force by the acceleration.
-- The quotient is the mass.

It should be constant, unless the moving object is something like a rocket,
which is constantly burning fuel and reducing its mass.

A railway train 50 m long passes over a bridge 250 m long at the rate of 12 km/h.How long will it take completely pass over the bridge?

Answers

From the instant when the nose of the locomotive reaches the beginning of the
bridge, it has to travel the whole 250m to get to the other end of the bridge, and
then it has to travel another 50m to get the rest of the train off the bridge.  So it
has to travel 300m to get everything it's pulling across the bridge.

Time = distance/speed = 300m / (12,000 m/hr) = 0.025 hour = 1 minute 30 sec
Pretty slow that train ;)

t=s/v
v=12 km/h=10/3 m/s
s=250+50=300 m

t=300/(10/3)
t=300*3/10
t=30*3
t=90 s=1.5 min

Which of the following would have the highest power rating? 500 J of energy used in 100 seconds 1,000 J of energy used in 100 seconds 500 J of energy used in 50 seconds 1,000 J of energy used in 50 seconds

Answers

Power is defined as the work produced per unit of time. The SI unit for power is the watt, which is also equivalent to Joules per second. Given the data above, the power can be directly calculated by dividing the work (joule) by the time (second). The one that gives the highest power of 20 watts is 1,000 J of energy used in 50 seconds.

The statement, "Energy can neither be created nor destroyed, but can change from one form to another," is what law?

Answers

In chemical reaction, atomsalways are rearranged. They are never destroyed or created because it wouldcontradict the law of conservation of energy. The law of conservation of energystates that energy can neither be created nor destroyed, but can change fromone form to another. Also it cannot be neutralized. Resulting in one cannot bepart of a chemical reaction. An example of this is the reaction HCl + NaOH-> NaCl + H2O. the reactants and products are not created, they are justformed into another substance.
