Answer:
Their measured results are closer to the exact or true value. Hence, their measured value is considered to be more accurate.
Explanation:
Considering the situation described above, the accuracy of a measured value depicts how closely a measured value is to the accurate value.
Hence, since the students' measured values have very low percent differences, it shows the similarity of computations or estimates to the actual values, which in turn offers a smaller measurement error.
Therefore, their measured results are closer to the exact or true value, which implies that their measured value is considered to be more accurate.
Answer:
The acceleration at lowest point is 19.62 m/s^2
Explanation:
Conservation of energy is an concept in which it is stated that the energy of an isolated object remains the same. Energy changes from one form to another.
Lets Assume
Constant of string is K
By using the conservation of energy we will have the following equation
1/2 x 80^2 x K = m x 9.81 x 120
3200 K = 1177.2 m
K = 1177.2 m / 3200
K = 0.368 m
At the lowest point we will have
a = ( K x X - m x g ) / m
a = ( 0.368 m x 80 - m x 9.81 ) / m
a = 19.62 m / s^2
So, the acceleration at lowest point is 19.62 m/s^2
Every fast-food chain is required by law to make the nutrition content of the
items on its menu publicly available.
My friend should walk into her favorite place, or into the nearest McRonald's,
Bendy's, Tennessee Fried Turkey, Bulgur King, Plucky Please, White Palace,
Pita Hut, Carl's Senior, Back in the Box, or any of those others, ask to see
the Manager, and ask the manager for a chart of nutritional information that
includes their french fries.
To be nice about it, she should do this at a time when the place is not too busy,
and the manager doesn't have a lot of more-important things that <em>need to be
done</em> <em>right now</em>.
Under the french fries, look at the serving size, and the figure for "Sodium"
in that serving, which is the nutrient that your body gets from salt. Less is
better. More is worse. For an adult, the CDC Institute of Medicine says
that 1500mg a day is 'adequate' for an adult. The US Food and Drug
Administration recommends that adults should get 'no more than' 2300mg
in a day. People who have high blood pressure are supposed to watch it,
and take in a lot less sodium.
And there are organizations with official-sounding names that totally dispute
all of this.
But to answer your question, that's what she should do to learn the amount
of salt used at the place where likes to get her french fries.
Answer:
The same.
Explanation:
Temperature is a measure of the average kinetic energy of a substance; if two pieces of iron have the same temperature, then their particles will have the same amount of average kinetic energy.
