5 (7) - 3 (-8)

35 - -24

Because two negatives equal a positive the subtraction sign will change into an addition sign.

Determine the gravitational force of attraction between two 3.5 kg bowling balls whose
Ipatiy [6.2K]

Answer:

F_G=2.04\ .\ 10^{-10}\ Nw

Option J

Step-by-step explanation:

Newton's Universal Law Of Gravitation

Newton discovered that all objects attract each other with a force of gravitational attraction which is proportional to their masses and inversely proportional to the square of the distance between them.

\displaystyle F_G=G\frac{m_1m_2}{d^2}\ ,\ G=6.673\ .\ 10^{-11} N m^2/kg^2

Where m_1, m_2 are the masses in kg and d is the distance between them in meters.

In the problem, we have

m_1=m_2=3.5\ kg

d=2\ meters

\displaystyle F_G=6.673\ .\ 10^{-11} N m^2/kg^2\frac{(3.5kg)(3.5kg)}{(2m)^2}

\boxed{F_G=2.04\ .\ 10^{-10}\ Nw}

Reika [66]

The greatest number of friends who can receive a necklace is 6. The reason why is because 6 is the greatest common factor of 72 and 42.

Each friend will have 12 blue beads and 7 red beads. If you divide 6 (GCF) with both numbers you get 12 and 7.

Hope this helps :3
