False. This is because ellipses have 2 focus points and not only one.

Answer:  Fluorine (F) and chlorine (Cl) are two good choices.  See reasoning below.

Explanation:  Mendeleev arranged the elements in the periodic table in a manner that each group, or vertical column, contained elements that exhibited similar chemical properities.  He even reserved spaces for undiscovered elements when none of the known elements had properties similar to those above or below the known elements in a group.  An interesting event illustrates this property.  In December 2010, NASA announced an important new discovery that was to be broadcast on live TV, creating much speculation (e.g., UFO's are real and we'll see the aliens sequestered at Roswell!!!  I knew it.).  

The actual announcement:

"Dec. 2, 2010:  NASA-supported researchers have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism, which lives in California's Mono Lake, substitutes arsenic for phosphorus in the backbone of its DNA and other cellular components."

A look at the periodic table shows arsenic just below phosphorus, in the same group.   This was an unexpected find, but it might have been predicted with an understanding of how the elements are organized.  

Side note:  look how close silicon is to carbon.  Can there be a life form whose being is made up of silicon instead of carbon?  Sure . . . why not?  Maybe not on Earth, but . . . wait . . . did that marble statue just wink?

Answer:

Joel has the faster speed.

Explanation:

Joel has a steeper slope on the graph. The steeper a slope is, the faster speed will be. Therefore, Joel's slope is steeper which increases overall speed.

Answer:

Very large and very small numbers written in standard form take up a large amount of space. They are hard to read and understand and are difficult to use in mathematics. One way to write a very large or very small number is to use a different form of notation. Converting to a workable number is done using scientific or engineering notation.

Explanation:

The precision of a balance is ±0.02 g.

The accepted value for a measurement is 26.86 g.

So,26.87 g is correct

I think atoms and molecules in matter are always in motion because of kinetic energy.

Answer:

in motion.

Explanation:

In chemistry, we often explain the states of matter in terms of the kinetic molecular theory (KMT). The word kinetic refers to motion and the kinetic molecular theory suggests that atoms and molecules are always in motion. The energy associated with this motion is termed kinetic energy.

Point out the following about solids: The particles (atoms or molecules) are attracted to each other. The particles (atoms or molecules) vibrate but do not move past one another. The solid retains its shape.

They are not always in motion. They are always in motion if and only if the temperature of the surroundings is greater than absolute zero ( 0 K ).

Not only are molecules really small but they are in constant motion. The motion is called “thermal motion” because it's caused by temperature. Increase the temperature around them and the molecules move faster.

The reaction force to your push is the push of box G against you.

Newton's third law states that:

For every action, there is an equal opposite reaction.

So if an object x pulls or pushes an object y with a certain force, object y also exerts an equal and opposite force on object x.

Now, if you should push box G with a certain force, box G will exert an equal opposite force on you.

Hence, the reaction force to your push is the push of box G against you.

Answer:

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Answer:

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]k = \frac{1}{2} m {v}^{2} \\[/tex]

m is the mass

v is the velocity

From the question we have

[tex]k = \frac{1}{2} \times 1000 \times {26}^{2} \\ = 500 \times 676 \\ = 338000[/tex]

Explanation:

Answer:

The object will contine to fall, but at a constant velocity.  There will be no more acceleration.

Explanation:  When the force of gravity is equal to the reverse force of air resistance, there will will be no net force on the falling obect.  F = ma, and F (net) = 0.  It will continue at the same speed until those forces become imbalanced again (such as when the force pushing up from the ground is greater than the force of gravity pulling it down).  The metric term for this sudden resistance is "crash/bang/clunk/yieouch."

The tension on the hitch that connects the trailer to the car is 160 N.

From the information provided;

Initial velocity = 0 m/s (the car started from rest)

Final velocity = 11 m/s

Time taken = 28 s

From the formula;

a = v - u/t

a = 11 - 0/28 = 0.39 ms-2

The force that acts on the trailer  = tension in the hitch that connects the trailer to the car

Force = mass × acceleration

Force = 410 kg × 0.39 ms-2

Force = 160 N
