Elastic
☑ occur when the colliding objects bounce off of each other
☑ hard or bouncy objects
☑ kinetic energy is conserved

Inelastic
☑ occur when two objects collide
☑ two objects colliding stick together
☑ kinetic energy is not conserved — some of the initial kinetic energy is converted into other types of energy (heat, sound, etc.)

If the potential due to a point charge is 5.05 ✕ 102 V at a distance of 15.7 m, what are the sign and magnitude of the charge? (

aleksklad [387]

Answer:

The magnitude of charge is $8.809\times 10^{-7}\ C$ with a positive charge.

Explanation:

Given that,

The potential due to a point charge, $V=5.05\times 10^2\ V$

Distance, d = 15.7 m

The potential due to a point charge is given by :

$V=\dfrac{kq}{d}$

q is charge

k is electrostatic constant

$q=\dfrac{Vd}{k}\\\\q=\dfrac{5.05\times 10^2\times 15.7}{9\times 10^9}\\\\q=8.809\times 10^{-7}\ C$

Here, the potential is positive, then the magnitude of charge is $8.809\times 10^{-7}\ C$ with a positive charge.

2134211-12431-24143x=1312431

kondor19780726 [428]

Answer:

33.5

Explanation:

The given expression is;

2134211 - 12431 - 24143x = 1312431

To solve this problem, simplify the similar terms;

2121780 - 24143x = 1312431

- 24143x = 1312431 - 2121780

- 24143x = -809349

divide both sides of the expression by -24143;

x = 33.5

Which of the 25 worst earthquakes in history will you do your research on? Why did you choose this earthquake?

Monica [59]

One of the worst earthquake i would say is the Valdivia earthquake

Ill say this one because the quake created a tsunami, which together killed an estimated 5,700 people

Hope this helps
