Answer:

-law of original horizontality

-law of superposition

-law of original lateral continuity

-law of cross-cutting or intrusive relationships

Explanation:

Relative dating is the science that many scientist use to set an order, or to figure out the order in which past events happened, this is without actually invetigating the natural age of the elements, and from stratigraphy and paleontology the laws of relative dating are:

Uniformitarianism
Intrusive relationships
Cross-cutting relationships
Inclusions and components
Original horizontality
Superposition
Faunal succession
Lateral continuity

Objects 1 and 2 attract each other with a gravitational force of 72.0 units. If the mass of Object 1 is one-fourth the original

Black_prince [1.1K]

Answer:

New gravitational force, F' = 216 units

Explanation:

Given that,

Gravitational force between object 1 and 2, F = 72 N

The gravitational force between two objects is given by :

$F=\dfrac{Gm_1m_2}{r^2}$

$\dfrac{Gm_1m_2}{r^2}=72$ ............(1)

If the mass of object 1, $m_1'=\dfrac{m_1}{4}$

$m_2'=3m_2$

If the distance between objects is halved, $r'=\dfrac{r}{2}$

Let new gravitational force is F'. It is changed to :

$F=\dfrac{Gm'_1m'_2}{r'^2}$

$F'=\dfrac{G\times \dfrac{m_1}{4}\times 3m_2}{(\dfrac{r}{2})^2}$

$F'=3\times \dfrac{Gm_1m_2}{r^2}$

$F'=3\times F$

$F'=3\times 72$

F' = 216 units

So, the new gravitational force will be 216 units.

If you could see the electric field coming off a proton you would notice that electric field lines are what?

Readme [11.4K]

The electric field generated by a proton is a radial field, so we would see the field lines going radially from the proton toward every direction. I've attached a picture representing the electric field generated by a positive charge, such as a proton, and we can see the field lines going radially from the charge toward every direction.
