The most dense thing inside the column is the little star. It's pink, and it's resting on the bottom of the cylinder.

The red part under the star is the solid base that the cylinder is standing in. It's probably wood or plastic, it's not free to move, and it's not involved in the experiment.

When sugar is poured from the box into the sugar bowl, the rubbing of sugar grains creates a static electric charge that repels

WARRIOR [948]

Explanation:

In order to calculate the force, we will use the following formula.

F = $k \frac{q_{1}q_{2}}{r^{2}}$

where, $q_{1} = q_{2} = 3.0 \times 10^{-11} C$

r = $8.0 \times 10^{-5} m$

Therefore, we will put the given values into the above formula as follows.

F = $k \frac{q_{1}q_{2}}{r^{2}}$

= $9 \times 10^{9} \frac{3 \times 10^{-11} \times 3 \times 10^{-11}}{(8.0 \times 10^{-5})^{2}}$

= $1.265 \times 10^{-3}$ N

Thus, we can conclude that the given two grains will repel each other by a force of $1.265 \times 10^{-3}$ N.

A spring hangs vertically. A 250 g mass is attached to the spring and allowed to come to rest. The spring stretches 8 cm as the

tiny-mole [99]

Answer:

spring constant = 31.25N/m

Explanation:

spring constant = force/extension

mass = 250g = 0.25kg

extension = 8cm = 0.08m

force = mg = 0.25 x 10 = 2.5N

spring constant = 2.5/0.08 = 31.25N/m
