Answer:

Chlorine and Fluorine

Explanation:

When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have seven electrons in their outer shell. That seven-electron trait applies to all of the halogens. They are all just one electron shy of having full shells.

Answer: Density, pressure, and temperature all increase as you go deeper into the Earth.

Explanation: Explanation: As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.

Answer:  For the volume of a regular shaped object, multiply the width and the length and then multiply the result by the height. As for the volume of an irregular shaped object, first break the object down into more regular shaped objects. Then calculate the volumes of the small regular shaped objects, and add all the volumes to get your answer.

As time passed The telephone poles cleaned and moved a little I’m guessing

Explanation:

There don't appear to be any dial tone problems on telephone caused by broken wires, connectors, wall jacks, or other network-interfering hardware.

When your telephone wire's phone isn't working, whether you don't hear a dial tone, can't dial out, or hear too much static, it may be quite aggravating.

We're here to assist you! This wiki How article will show you how to troubleshoot all kinds of landline issues that develop in your house or workplace, including damaged jacks, defective wiring, and interference issues.

Your cordless phone's batteries need to be replaced. Customers of Pure Broadband who solely use our internet service may hear a dial tone, but they do not actually have a working telephone.

Therefore, The telephone poles became cleaner and slightly more mobile as time went on.

Answer:

Force is defined as the rate of change of momentum (momentum is mass multiplied by velocity) with respect to time. Work is the product of displacement and the component of force in the direction of displacement. If work is done, then the kinetic energy of an object changes.

Explanation:

That is the difference between force and work

Answer:

/

Explanation:

Answer:

B and D ( not absolutety sure though)

Answer:

0.4 hour or 24 minutes

Explanation:

Speed =displacement /time

25miles/hour=10/time

10/25=time

0.4hour=time

Answer:

24 minutes

Explanation:

• If the speed limit is 25miles/hour, it takes 2.4 minutes to travel 1 mile.

60mins/25miles

= 2.4 minutes

• Therefore to travel 10 miles;

2.4 minutes × 10

= 24 minutes

Answer:

superconductor  conductor  semiconductor  insulator

Explanation:

Edge

The list's type of materials from most conductive to the least conductive will be superconductor,conductor,semiconductor and insulator.

Semiconductors are materials with conductivity intermediate between conductors and nonconductors or insulators. Semiconductors may be either compound like gallium arsenide.

The ideas, characteristics, and mathematical techniques that control semiconductors are explained in physics.

Silicon is employed in the manufacturing of electrical circuits, whereas gallium arsenide is used in solar cells, laser diodes, and other applications.

The types of materials from most conductive to least conductive will be superconductor,conductor,semiconductor and insulator.

Hence, option B is correct.

Answer: You may want to mention the equal but opposite force of shooting a gun. (The recoil force vs. the bullet).  Also, if you bounce a ball really hard, it will exert force that makes it bounce high up, and this is the same if you were to bounce the ball with little force. Also, a judge's gavel creates a sound (sound waves would be the opposite force here) after it is hit on the podium. Lastly, if you blow up a balloon without tying it, then let it go, the trapped moving particles will make the balloon fly and flail until there is no more pent-up energy inside the balloon.

Answer:

Answer: Options A, B, and E

Explanation:

The gravitational pull on an object by another, is nothing but the force that it exerts due to its gravity. Earth has gravity, so it pulls down everything that tends to move up. Similarly, Hox and Blox have gravitational pulls on each other, due to their gravitational forces.

Where,

F = force exerted on object

G – Gravitational constant

– Mass of two objects

r – Distance between two objects

This gravitational pull varies in phase with the mass of two bodies in relation, and inversely proportionate to the distance square. Hence, the scientist could do less the distance between the bodies, or else, spend to increase the size of one of them or both the bodies.

Explanation:

The top of the loop cannot be the same height as (or higher than) the top of the first hill because of loss of energy against frictional force in the track.

The energy that an item has or acquires when its location changes as a result of being in a gravitational field is known as gravitational potential energy. Gravitational potential energy can be defined as an energy that has a connection to gravitational force or gravity.

The force produced by two surfaces coming into contact and sliding against one another is referred to as frictional force.

Surface roughness and the amount of force pressing them together have the biggest an impact on these forces.

The frictional force will increase and surpass the weight of the thing if an object is pushed up against the surface.

In this question, the roller-coaster starts its journey from point B and during its course of journey its potential energy at point B converts into kinetic energy and it losses some about of its kinetic energy working against frictional force. So,  the height of very top of the loop (point D) should be  less than that of  the first hill (point B).
