Answer:

d=5.33\ gr/cm^3

Explanation:

<u>Densidad</u>

La densidad de una masa m que ocupa un volumen v se define como:

\displaystyle d=\frac{m}{V}

Tenemos que una masa de 80 gr hace que un volumen de agua se desplace desde 60 cm3 hasta 75 cm3, es decir, el volumen propio de la masa es m = 75 - 60 = 15 cm3.

Con esta información se calcula la densidad:

\displaystyle d=\frac{80\ gr}{15\ cm^3}

Operando:

\boxed{d=5.33\ gr/cm^3}

Which of the following is not a sedimentary structure?A) Magma emplacementB) Mud cracksC) Ripple marksD) Cross beds
lawyer [7]

Answer:

A) Magma emplacement

Explanation:

Sedimentary structures forms during deposition of sediments. It can also form after sediments have been deposited. Sedimentary structures can only be found in sedimentary rocks. Some examples include mud cracks, ripple marks, cross stratification, potholes, etc

Magma emplacement is an igneous process which describes the different mechanisms by which magma can be emplaced. It is only typical of igneous rocks.

DOUBLE POINTS AND BRAINLIEST ANSWER PLEASE THIS IS VERY IMPORTANT FOR UNIT TEST TOMORROW for each of these diagrams in the pictu
Anni [7]
Maybe nobody ever mentioned it to you, but it turns out that
current is another one of those things that's always conserved ...
it can't created or destroyed, just like energy and mass. 

The total current in a circuit is always the same, but it can get
split up and travel through different paths for a while.

<span>==>  The total current is just the amount of current
         that's flowing in
and out of </span><span>the battery.

Diagram #1).
</span>The total current coming out of the battery is 15 A.
That current is going to split up when it reaches the resistors.
   Part of it will flow through each resistor, but both of them
   will still add up to  15 A .
You have  9 A  flowing through one resistor.
So the current in the other resistor is  (15 - 9)  =<span>  6 A.

Diagram #2).
</span>The total current coming out of the battery is 10 A.
That current is going to split up when it reaches the resistors.
   Part of it will flow through each resistor, but all of them
   will still add up to  10 A .
You have  2.5 A  through one resistor and  3.5 A through another one.
So the amount left for the last resistor is  (10 - 2.5 - 3.5)  =<span>  4 A.</span>

How much current is drawn by a television with a resistance of 30 ω that is connected across a potential difference of 120v?
melomori [17]

By using the Ohms law, we can calculate the current.

Ohms law,

 \frac{V}{I}  = R

Here, V is potential difference, and R is the resistance.

Given,  V=120 V and R = 30 ohm.

Therefore, putting the given values in above relation , we get

\frac{120V}{I} = 30 ohm

or          I=\frac{120}{30} = 4 A

Thus, the current is drawn by a television 4 Ampere

The force of repulsion between to like charge table tennis balls is 8.2 X 10 ^-7 N if the charge on the two objects a 6.7 X10^-9
Svetllana [295]

Answer:

0.702 m

Explanation:

The magnitude of the electrostatic force between two charged objects is given by Coulomb's Law:

F=k\frac{q_1 q_2}{r^2}

where

k is the Coulomb's constant

q1, q2 are the two charges

r is the separation between the objects

And the force is:

- Attractive if the two charges have opposite signs (+-)

- Repulsive if the two charges have same sign (++ or --)

In this problem we have:

F=8.2\cdot 10^{-7}N is the force between the two balls

q_1 = q_2 = 6.7\cdot 10^{-9}C is the charge on each ball

Solving for r, we find the separation between the balls:

r=\sqrt{\frac{kq_1 q_2}{F}}=\sqrt{\frac{(9\cdot 10^9)(6.7\cdot 10^{-9})^2}{8.2\cdot 10^{-7}}}=0.702 m
