Metallic bonds hold metal atoms and freely moving valence electrons together, while Van der Waals forces hold nonpolar molecules together. OD. Metallic bonds hold metal atoms and freely moving valence electrons together while Van der Waals forces hold atoms together when they share valence electrons.

Explanation:

this is almost similar to how a syringe works. when the pump is drown out, air in the barrel expands and pressure is reduced to below atmospheric pressure. the air from outside the pump is at high pressure so it flows past the leather washer into the barrel. at some point, the higher pressure in the tyre closes for valve.

when the pump handle is pushed in the air is forced into the tyre though the tyre valve which now opens

Answer:

Object X reflects yellow and object Y reflects none.

Explanation:

We are able to see the colors of different objects because the light rays falling on the surface of an object reflects back few or none of the colors to our eyes. We see the color that is reflected back to our eyes.

In the context, Marcy has two objects, X and Y. We see that object X is yellow in color because as the light rays falls on the object X, it absorbs all the colors of the spectrum and reflects the color yellow back to our eyes. So we can see that the object X is yellow.

Similarly, when spectrum light falls on the surface of the object Y, it absorbs all light in its body and reflects none of its colors. So the object Y appears to be black to our eyes.

Answer: The sun's rays strike Earth's surface most directly at the equator. This focuses the rays on a small area. Because the rays hit more directly, the area is heated more.

The light is most intense where it strikes Earth's surface most directly at the equator

Explanation: Use of these terms stretches back to World War I. One American field order from September 1918 noted, “The First Army will attack at H-Hour on D-Day with the object of forcing the evacuation of the St. Mihiel salient.” Other nations had their own shorthand. In World War I, the French used the code date “le Jour J,” while the British called their operation start days “Z-Day” and “Zero Hour.”

You and your younger sister (who weighs half as much you do) are at a skating rink. You and your sister's both move backward but your sister accelerates at a greater rate.

The time rate of change of velocity with time.

As both are holding each other, they will be pushed backwards because the skating they wear makes them to move backwards. The equal and opposite force is applied on each other.

The force F =mass x acceleration.

The lesser mass greater will be the acceleration. Your sister with half weight of yours will accelerate more.

Thus, you and your sister's both move backward but your sister accelerates at a greater rate.

Answer: How much gravitational potential energy does the ball have at this point? At h = 20.4 m the gravitational potential energy of the ball reaches maximum.  

How much work did I do lifting up the ball?  As you are lifting the object you are doing work on the object. The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.

Answer:

D

Explanation:

Answer:

La masa del objeto es 270.027 kilogramos.

Explanation:

Asumamos que el cuerpo decelera a tasa constante, entonces podemos calcularlo por medio de la siguiente ecuación cinemática:

[tex]a = \frac{v-v_{o}}{t}[/tex] (1)

Donde:

[tex]v_{o}[/tex] - Velocidad inicial, en metros por segundo.

[tex]v[/tex] - Velocidad final, en metros por segundo.

[tex]t[/tex] - Tiempo, en segundos.

[tex]a[/tex] - Deceleración, en metros per segundo al cuadrado.

Si sabemos que [tex]v_{o} = 33.889\,\frac{m}{s}[/tex], [tex]v = 13.889\,\frac{m}{s}[/tex] y [tex]t = 4.5\,s[/tex], entonces la deceleración experimentada por el cuerpo es:

[tex]a = \frac{v-v_{o}}{t}[/tex]

[tex]a = -4.444\,\frac{m}{s^{2}}[/tex]

Por las Leyes de Newton, tenemos que la masa del cuerpo se calcula a partir de la siguiente expresión:

[tex]m = \frac{F}{a}[/tex] (2)

Donde:

[tex]m[/tex] - Masa, en kilogramos.

[tex]F[/tex] - Fuerza de frenado, en newtons.

Si sabemos que [tex]F = -1200\,N[/tex] y [tex]a = -4.444\,\frac{m}{s^{2}}[/tex], entonces la masa del cuerpo es:

[tex]m = \frac{F}{a}[/tex]

[tex]m = 270.027\,kg[/tex]

La masa del objeto es 270.027 kilogramos.

Answer:

Magnetic energy is used by an electromagnet  to pick up metallic objects

Explanation:

An electromagnet generates its own magnetic field in presence of electric current.

As an electric current is induced in an electromagnet , it  magnetic dipole arrange themselves in order to behave as a magnet and hence generate magnetic field with a proper north and south. This leads to attraction of metallic object.

Hence, it can be said that Magnetic energy is used by an electromagnet  to pick up metallic objects

Answer: The correct answer is A). Animal burrow because burrow fossils represent the preserved byproducts of behavior rather than physical remains, they are considered a kind of trace fossil. One common kind of burrow fossil is known as Skolithos, and the similar Trypanites, Ophiomorpha and Diplocraterion.

Animal burrow is  an example of a trace fossil.

The preserved remnants of plants and animals that were submerged in sediments like sand and mud beneath ancient seas, lakes, and rivers are known as fossils. Any preserved sign of life that is typically older than 10,000 years is considered a fossil.

After death, soft body parts degrade quickly, while hard body parts, including bones, shells, and teeth, can be replaced by minerals that solidify into rock. Soft components like feathers, ferns, or other signs of life, such footprints or faeces, may also be preserved in extremely rare circumstances. Both less familiar fossils like ammonites and trilobites as well as microscopic-sized ones like single-celled foraminifera or pollen grains can be found in the remains.

A trace fossil, also known as an ichnofossil, is a record of biological activity preserved in the fossil record but without the actual preserved plant or animal remains. Contrasting with body fossils, which are the preserved remains of portions of an organism's body that were typically modified by later chemical activity or mineralization, are trace fossils. Ichnology, the study of such trace fossils, is the field of study of iconologists.

Explanation:

The average density of the human body is 985 kg/m3 k g / m 3 , and the typical density of seawater is about 1020 kg/m3 k g / m 3 .

Explanation:

the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2 (38 per sq. mi.). If only the Earth's land area of 150,000,000 km2 (58,000,000 sq. mi.) is taken into account, then human population density is 50 per km2 (129 per sq.

Answer:

Work is defined as force thru a distance:   W = F * S

Power is defined as Work per unit time  P = W / t

So we an write:  P = F * S / t  = 2000 N * 50 m / 5 s = 20,000 N-m/s

Since a Joule/sec is equivalent to a Watt

The power required is 20,000 Watts or 20  Kw

Also, you can convert to Hp since 1 Hp = 746 Watts
