The force newton(N),between two particles is inversely propotional to the square of the distance ,d m,between them.When particle

bonufazy [111]

Answer: $1.6\ N$

Step-by-step explanation:

Given

The force between the two particles is inversely proportional to the distance between them

$\Rightarrow F\propto \dfrac{1}{d^2}$

When the distance is 2 m, the force is 10 N. For 5 m distance, it is

$\Rightarrow \dfrac{10}{F_o}=\dfrac{5^2}{2^2}\\\\\Rightarrow F_o=10\times \dfrac{2^2}{5^2}\\\\\Rightarrow F_o=1.6\ N$

Thus, the force between them is $1.6\ N$

Triangles PQR and STU are similar. The length of PQ = 36 cm, RP = 48 cm and QR = 24

gladu [14]

Answer:

207 cm

Step-by-step explanation:

Because ΔPQR ≅ΔSTU and the longest side in the ΔPQR is RP then the longest side in ΔSTU must be SU = 92 cm

Perimeter of triangle PQR is

P(ΔPQR) = 36+48+24 = 108 cm

Because the triangles are are similar their sides are in proportion.

But how much bigger did the second triangle get?...is (92/48) times bigger

P(ΔSTU) = 180*(92/48) = 207 cm

...you can also use proportions to find each side and then find the perimeter

TU = 24*92 /48 = 46

TS = 36*92/48 = 69

SU = 92

P(ΔSTU) = 92+69+46 =207 cm

*the triangles are not drawn to scale
