A satellite orbits Earth. The only force on the satellite is the gravitational force exerted by Earth. How does the satellite’s
bulgar [2K]

Answer:

here we can say that acceleration of the satellite is same as the gravitational field due to Earth at that location

Explanation:

As we know that gravitational field is defined as the force experienced by the satellite per unit of mass

so we will have

E = \frac{F}{m}

now in order to find the acceleration of the satellite we know by Newton's II law

F = ma

so we will have

a = \frac{F}{m}

so here we can say that acceleration of the satellite is same as the gravitational field due to Earth at that location

Of the numbers 0.0034 m, 45.6 m, and 1234 m, which is the most precise?
julia-pushkina [17]

Answer:

The most precise is 0.0034 m ⇒ 1st answer

Explanation:

<em>Lets revise the meaning of precise</em>

Precision is referred as the closeness of two measurements to one

another.

Highest number with significant digit is the most precise

Ex: <em>Highest significant </em>of optical instrument is the Wavelength of visible (red)

light = 0.00006 cm

Hence the <em><u>most precise</u></em> device for measuring length is the given optical

instrument

The difference between accuracy and precise

<em>Accuracy</em> is how close a value is to its true value

<em>Precision</em> is how repeatable a measurement is

We have three numbers

0.0034 m, 45.6 m, and 1234 m

The least precise is 1234 m

The most precise is 0.0034 m
