Answer: the force of impact is the same in magnitude for both the winshield and the bug, and in opposed directions.

Explanation:

1) Whenever two objects are in contact you have to think about the Third Law of Newton, named action-reaction force.

2) According to this law, action and reaction have the same magnitude but opposite directions.

3) Think that forces always come in pairs. They act over different objects, have the same magnitude and act on opposite directions. Some additional examples are:

i) When you kick a stone, the force of your foot on the stone is the same force of the stone on your foot.

ii) When you stand on the ground, the force that your feet exert on the ground is equal to that that the ground exerts on you feet, but in opposite direction.

iii) When you push a block, the block pushes you with the same magnitude.

Desde que altura debes de lanzar una canica de 50g para que adquiera una energia de 100j

AnnZ [28]

Answer:

204 m

Explanation:

When the marble is dropped from a certain height, its gravitational potential energy converts into kinetic energy. So the kinetic energy gained is equal to the variation of gravitational potential energy:

$\Delta U=mg\Delta h$

where

m is the mass of the marble

g = 9.8 m/s^2 is the acceleration of gravity

$\Delta h$ is the change in height

In this problem, we have

m = 50 g = 0.05 kg

$\Delta U = 100 J$

Solving the formula for $\Delta h$ , we find the necessary height from which the marble should be dropped:

$\Delta h = \frac{\Delta U}{mg}=\frac{100}{(0.05)(9.8)}=204 m$

Coulomb is a very large unit for practical use. Justify your answer if 10^10 electrons are transferred from a body/second

zlopas [31]

Given:

10^10 electrons per second

To justify that coulomb is a very large unit for practical use, we need to convert the quantity of electron given to Coulombs:

From literature,

1 Coulomb is equivalent to 6.242×10^18 electrons.

So,

= 10^10 electrons * (1 coulomb/6.242×10^18 electrons) / second
= 1.602 x 10^-9 coulumbs

This value is too small to be used in an actual setting.
