Question 2 of 10
Which illustration represents low accuracy and low precision?

Answers

The illustration represents low accuracy and low precision is according to option D.

What is accuracy?

When in an experiment, a value is measured 5 times, then if the values measured are same for most of the time or like three times out of five, it said to be accurate. The phenomenon is accuracy.

Precision is about comparing the values to each other then find them near to each other.

Accuracy compares the experimental value to the theoretical value.

So, when all the values are close to each other but not nearest to the theoretical value, then it is said to be precise but not accurate.

Thus, the correct option for low accuracy and precision is D.

Average velocity is different than average speed because calculating average velocity involves what?

Answers

Two things that aren't involved in speed: -- the straight-line distance between the start- and end- points. -- the direction from start-point to end-point.

The correct answer to the question is: Direction

EXPLANATION:

The average velocity of a body is defined as the rate of change of displacement.

We know that displacement is a vector quantity. Hence, it has magnitude as well as direction for its specification.

On the other hand, the average speed of a body is defined as the rate of change of distance travelled. Hence, the average speed of a body is a scalar quantity. It means that it has only magnitude.

Hence, during the calculation of average velocity,we have to think of its direction.

you measure that it takes 0.75 seconds for a leaf to fall from a tree to the ground. the leaf experiences air resistance as it falls. if there were no air resistance, how long would it take the leaf to fall?

Answers

There's not enough information given in the problem to calculate that answer.

A leaf falling from a tree on Earth, a sheet of printer paper falling off the back
of a truck on Venus, and a steel ball sinking through a bucket of Scotch whiskey
on Mars, might all reach the bottom in 0.75 second.  The time it would take each
of them to fall the same distance through a vacuum in the same place would be
different, and the 0.75 second is not enough to enable you derive it ... even if
you did know the acceleration of gravity in each place.  All you can say is that
without resistance, it would fall faster, and hit bottom in less than 0.75 second.

Answer:

less than 0.75 seconds

What is the approximate diameter of an inflatedbasketball?
(1) 2 × 10^–2 m (3) 2 × 10^0 m
(2) 2 × 10^–1 m (4) 2 × 10^1 m

Answers

The approximate diameter of an inflated basketball is 2 × 10^–2 m. The answer is number 1. The rest of the choices do not answer the question above because they are too big for the diameter of the basketball.

Our solar system formed from a huge cloud of dust and gas called a _____.a. disk
b. protostar
c. solar nebula
d. planetesimal

Answers

The correct answer is C. Solar nebula

Explanation:

According to scientists, the Solar nebula was rotating disk or cloud of dust and gas (mainly hydrogen and helio) that is believed was the origin of our solar system. Indeed, it is estimated the formation of our solar system began 4.6 billion years ago as the solar nebula began contracting forming first the sun in the center and then other elements such as planets. This theory was first proposed in 1734 by Emanuel Swedenborg; however, from the first proposal, multiple models have emerged related to this theory and nowadays, the solar nebula theory is the one that scientist believe explain the formation of our solar system and other solar systems. Thus, our solar system formed from a huge cloud of dust and gas called a solar nebula.

c. solar nebula

Based on the nebular hypothesis, our solar system formed from hydrogen gas and interstellar dust. The gas and the dust contracted and formed the early stage of the sun.
