You said T = 2 · π · √(L / g)

(I think that's the formula for the full-swing period of a simple pendulum.)

Divide each side by 2π : T/2π = √(L / g)

Square each side: (T/2π)² = L / g

Multiply each side by ' g ' : L = g · (T/2π)²

Increase the mass of the beanbag its gravitational potential energy will

kotegsom [21]

The gravitational potential energy will increase

Explanation:

The gravitational potential energy (GPE) of an object is the energy possessed by the object due to its position in a gravitational field.

Near the Earth's surface, the GPE of an object is given by

$GPE=mgh$

where

m is the mass of the object

g is the acceleration of gravity

h is the heigth of the object above the ground

From the equation, we see that the GPE is directly proportional to the mass: therefore, if the mass increases, the GPE will increase as well.

So, for the beanbag in this problem, when its mass increases, the GPE will increase as well.

What does it mean if a paint sample "matches" a known sample from a vehicle? Does this indicate the same source? Why or why not?

Mandarinka [93]

It wouldn't indicate the same source if the paint was from a different place. If the paint was the same brand and color it would be but if not then no

Juan is making ice tea. When he adds ice to the tea, why does the tea cool down?

Tresset [83]

Answer: because the ice was cold, and it melted in the tea. So the tea is now cooler.

The magnitude of the electrostatic force between two identical ions that are separated by a distance of 5.0A is 3.7×10^-9N.a) wh

jeyben [28]

Explanation:

Given that,

Electrostatic force, $F=3.7\times 10^{-9}\ N$

Distance, $r=5\ A=5\times 10^{-10}\ m$

(a) $F=\dfrac{kq^2}{r^2}$ , q is the charge on the ion

$q=\sqrt{\dfrac{Fr^2}{k}}$

$q=\sqrt{\dfrac{3.7\times 10^{-9}\times (5\times 10^{-10})^2}{9\times 10^9}}$

$q=3.2\times 10^{-19}\ C$

(b) Let n is the number of electrons are missing from each ion. It can be calculated as :

$n=\dfrac{q}{e}$

$n=\dfrac{3.2\times 10^{-19}}{1.6\times 10^{-19}}$

n = 2

Hence, this is the required solution.
