how are atoms in a molecule held together?

A.through shared protons

B.through shared electrons

C.through shared neutrons

D.through shared energy

Answers

Answer 1

Atoms held together through shared electrons.

A molecule is composed of atoms. Atoms are the smallest particles of a substance which can take part in a chemical reaction. Atoms are composed of electrons and the electrons in the outermost shell of atoms help bond atoms together in a molecule.

Hence, atoms are held together in molecules by electrons so they are held together through shared electrons.

Un automóvil circula a una velocidad de 60 km/h durante 1 hora y 15 minutos, después se para durante 5 minutos y luego regresa hacia el punto de partida a una velocidad de 10 m/s durante 45 minutos. Halla: a) La posición final. b) La distancia recorrida. c) La velocidad media.

Answers

Answer:

(a) 48 km

(b) 102 km

(c) 48.96 km/h.

Explanation:

Assuming that at first, the car travels from point A to point B, then the cat returns from point B to point C.

As the car traveled from point A to point B in 1 hour 15 minutes with a speed of 60 km/h.

Using distance = speed x time, so

Distance traveled from A to B is

[tex]d_{AB}= 60 x 1.25=75[/tex] km [ as time = 1 h 15 min = 1.25 h]

Stop time at point B is 5 minutes.

For the return journey, from point B to C:

Speed = 10 m/s

Time = 45 minutes = 45 x 60 seconds = 2700 seconds

Distance traveled from point B to C is

[tex]d_{BC}=[/tex] 10 x 2700 = 27000 meters

as 1000 meters = 1 km, so

[tex]d_{BC}=[/tex] 27 km.

(a) The final position of the car from the starting point A is the distance between points A and C.

[tex]d_{AC}=[/tex]75 -27=48 km.

Hence, the car is 48 km away from point A.

(b) Total distance traveled,

[tex]d= d_{AB}+d_{BC}=[/tex]75+27=102 km.

(c) Total time taken

t= 1.25 hour + 5 minutes + 45 minutes

= 5/4 hour + 5/60 hour + 45/60 hour [ as 1 hour = 60 min]

=25/ 12 hours.

Total distance traveled, d= 102 km [ from part (b)]

Average speed = (Total distance traveled)/(Total time taken)

=102/ (25/12)= 48.96 km/h.

Hence, the average speed of the car is 48.96 km/h.

Un prisma rectangular de cobre, de base igual a 36 centímetros cuadrados y una altura de 10 cm se sumerge hasta la mitad por medio de un alambre en un recipiente que contiene alcohol ¿que volumen de alcohol desaloja?

Answers

La respuesta correcta es 180 centímetros cúbicos o 180 [tex]cm^{3}[/tex]

Explicación:

El primer paso para saber cuanto alcohol desaloja el prisma es calcular el volumen total del prisma. El volumen se puede encontrar usando la formula V (Volumen) = B (base) x h (altura). El proceso se muestra a continuación:

V  = B x h

V = 36 [tex]cm^{2}[/tex] x 10 cm

V= 360 [tex]cm^{3}[/tex]

Finalmente, el volumen total del prisma debe dividirse en 2 considerando que solo la mitad del prisma fue sumergida y esta mitad equivale al volumen del alcohol desplazado.

360 [tex]cm^{3}[/tex] ÷ 2 = 180 [tex]cm^{3}[/tex]  

El volumen de fluido desplazado es de 180 cm^3.

Sabemos que el objeto va a desplazar su propio volumen de fluido. Por lo tanto, necesitamos obtener el volumen del objeto a, este es el volumen del fluido que eventualmente será desplazado por el sólido.

El volumen del sólido es;

V = 36 cm^2 * 10 cm^2 = 360 cm^3

desde que se sumergió a la mitad, volumen de alcohol desplazado = 360 cm^3/2 = 180cm^3

It takes 50 seconds for Tyler to do 450 Joules of work. How much power did Tyler use?​

Answers

Power=work/time
So,
Power =450/50=9watts

Answer:

Power = 450 Joules / 50 seconds = 9 J/s = 9 W *average* power

Explanation:

Power = Energy / Time ( or Work / Time) just as Velocity = Distance / Time

So, the average power needed for 50 seconds to do 450 Joules of work is simply 450 J / 50 s = 9 J/s = 9 Watts  (The unit Watt is defined so that 1 Watt = 1 Joule / Second).  It's important to note that 9W is the *average* power. The problem does not say that Tyler does work at a constant rate, so it's worth adding that caveat to the answer!

The convection area is just above the radiation zone. As materials from the suns core are heated, they rise above the radiation zone towards the EDGE of the convection area then sinks back again into the radiative zone for more heat.

The radiative zone is 12.6 million Fahrenheit hot and is just above the core.

Which substance freezes at the lowest

temperature?

A. Alcohol

B. Nicotine

C. Formaldehyde

Answers

Answer:

The correct option is A

Explanation:

Firstly, it should be noted that the freezing point of a substance can be assumed to be melting point of that substance because a substance will normally change from liquid to solid (freezes) at the same point it changes from solid to liquid (melts). For example, water freezes at 0°C and also starts melting at 0°C.

Thus, the substance with the lowest melting point among the substances mentioned in the question is alcohol (ethanol) with the melting point of -114°C. Hence, ethanol also has the lowest freezing point thereby freezing at the lowest temperature.

If a 50 N force was applied to a really massive object as well as a tiny object, what can you say
about the object's acceleration?

Answers

Answer:

The tiny object's acceleration will be much greater.

Explanation:

Because of Newton's second law of motion, (which is F=ma or Force= Mass*acceleration), then if the force maintains the same (which in this case it does, because it says 50 N to both obejcts) and  one mass was much greater than the other, then the ould be less for the more massive object and much greater for the lighter object.

For example:  If 50 N were applied to a 500 kg object and a 50 kg object, then theformulas for each (respectively) are:

50 = 500*acceleration

and

50 = 50*acceleration

(Because of Newtons Second Law of Motion)

Then, solving for the equations, we get for equation 1:

Acceleration = .1 m/s^2

And for equation 2:

Accleration = 1 m/s^2

Thus, you can see that more massive objects (when applied he same amount of force as the smaller object) clearly have less accleration than the smaller objects.

Dorji weight 1500n.if the total surface area of soles of his feet is 0.5 m2 what is the pressure exerted by his body on the ground​

Answers

Answer:

P = 3000 Pa

Explanation:

Weight of Dorji, W = F = mg = 1500 N

The total surface area of soles of his feet is 0.5 m²

We need to find the pressure exerted by his body on the ground​. The pressure is equal to the force acting per unit area. So,

[tex]P=\dfrac{1500\ N}{0.5\ m^2}\\\\=3000\ Pa[/tex]

So, the pressure exerted by his body on the ground​ is 3000 Pa.

The reactivity of metals increases as you move left in a period and as you move down in a group, so Marie needs to know the period and group of the element inside each box. Boxes that show locations in groups 1 or 2 or in period 8 contain the most reactive elements.

Explanation:

Answer:

The Group Number of the elements.

Explanation:

If Marie knew the group number of the elements, then she could determine the amount of valence electrons each element has and their reactivity rate. For example, if one box tells her that an element is located in group 18, then she could determine that the element is not very reactive. This is because elements in group 18 have 8 valence electrons, which makes them stable/unreactive.

Answers

Use the definition of average acceleration:

a = ∆v / t

If v is the starting speed, then ∆v = 0 - v, so solve for v :

-6.42 m/s² = (0 - v) / (2.85 s)

v = (6.42 m/s²) (2.85 s)

44°F =  6.6666666667°C

-56°F = -48.888888889°C

So, if u want whole number as the answer

it is something like 6.6666666667°C +  48.888888889°C = 55.5555555557 °C
