Answer:
The percentage error e% = Δm/m 100
Explanation:
The absolute error is the assessment with which measurements are made, it is given by the minimum reading value of a given instrument.
The accepted value is the value measured in an instrument. Or the one calculated by an experiment.
The percentage error is the ratio of the absolute error between the value of the average per 100
e% = Δm/m 100
Even though the object is weightless, it would need inertia, I.e, you pushing it or any form of transportation. So you would still have to push that 500kg to just keep it moving in space. Say if it were a planet with less gravitational force, it would be weightless.
Answer:
D)
Explanation:
The Period-Luminosity relationship tells us that luminosity increases with the period, and of course the more luminosity a star has the more far away they can be seen, so from this we know that:
A) False since lower luminosities can be observed when they are close.
B) False since longer periods means higher luminosities
C) False since lower luminosities can be observed when they are close.
D) True: Variable stars with shorter periods have lower luminosities, so they can only be observed when they are close.
