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

$m_1=m_2=3.5\ kg$

$d=2\ meters$

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

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

B. Rob would like to create a triangle that is

Phantasy [73]

Answer:

$14y + 9$

Step-by-step explanation:

Perimeter of the given triangular above = sum of all its sides.

$= (y + 9) + 2y + (4y - 1) = y + 9 + 2y + 4y -1$

Collect like terms

$= y + 2y + 4y + 9 - 1$

$= 7y + 8$

If Bob creates a new triangle that is 7 less than twice of the perimeter of the triangle above, the expression of the new triangle would be:

$2(7y + 8) - 7$

Simplify

$2*7y + 2*8 - 7$

$14y + 16 - 7$

New perimeter = $14y + 9$
