Answer:

Gravity holds stars together and keeps us on the ground. The electromagnetic force ensures the stability of atoms and makes chemistry happen. The strong nuclear force holds the kernels of matter, atomic nuclei, together, and powers the burning of stars.

Answer:

x = 54.15 meters between the balloons horizontally.

Explanation:

Hence, vertical distance between balloons is 12.8 meters.

y= 61-48.2 = 12.2 m

A right-angle triangle is formed with,

angle θ = 13.3 degrees

opposite (y) = 12.8

adjacent (x) = ?

$tan\theta = \dfrac{y}{x}$

Now by putting the values in the above equation.

$tan13^{\circ}=\dfrac{12.8}{x}$

$x=\dfrac{12.8}{tan13^{\circ}}$

x = 54.15 meters between the balloons horizontally.
