Answer:

Hey

A proton(s), and neutron(s).

B electron(s).

The nucleus (A) contains TWO particles, together they are called nucleons because they are in the nucleus. The two particles in the nucleus are the proton and neutron, they are held together by the nuclear strong force.

Outside of the nucleus, the electron takes up space around the nucleons. It is held in place by the electromagnetic force. It can only be a certain distance from the nucleus as you can see (the two circles around the nucleus). It can not be in between those two distances.

A rocket firing its engine and accelerating in outer space (no gravity, no air resistance) suddenly runs out of fuel. Which best

notsponge [240]

the correct choice is

D. It immediately stops accelerating, and continues moving at the velocity it had when burnout occurred.

as soon as the rocket runs out of fuel, its engine stops firing gases which is mainly responsible for the acceleration of the rocket. hence the rocket stops accelerating. also, since there is no gravity or air resistance , there is no net force on the rocket after it runs out of the fuel. hence

a = acceleration = 0

we know that , at no acceleration , object moves at constant velocity. hence the rocket keeps moving at the velocity it had when burnout occured.

One heater uses 310 W of power when connected by itself to a battery. Another heater uses 180 W of power when connected by itsel

igor_vitrenko [27]

Answer:

55.8W

Explanation:

P= V^2/R

R= V^2/P

For series connection

Req= R1+ R2= V^2/310 + V^2/180

R=V^2/P= V^2/310 + V^2/180

But V^2 will cancel out

P= 1/(1/310 + 1/180)

P= 55.8W

Any Acellus folk figure out the answer to this one??? I CANNOT for the life of me.

Olin [163]

Answer:

-0.10472 $\frac{rad}{s}$

Explanation:

Remember that any clockwise rotation is considered negative, and any counterclockwise rotation is considered positive.

The formula for period is:

$T = \dfrac{2\pi}{\omega}$

Solve for $\omega\\$ and you get:

$\omega=\dfrac{2\pi}{T}$

The period is 60 seconds so make that division and you're left with -0.10472 $\frac{rad}{s}$ or -0.10 $\frac{rad}{s}$ if significant figures apply (negative because the rotation is clockwise).

El tubo de entrada que suministra presión de aire para operar un gato hidráulico tiene 2 cm de diámetro. El pistón de salida es

Bess [88]

Answer:

La presión neumática para levantar un automóvil de 17,640 newtons es 220,500 pascales.

Explanation:

Asumiendo que la presión ( $P$ ), medida en pascales, tiene una distribución uniforme sobre la superficie del pistón, se calcula a partir de la siguiente expresion:

$P = \frac{F}{A}$

Donde:

$F$ - Fuerza motriz, medida en newtons.

$A$ - Área del pistón, medida en metros cuadrados.

La fuerza motriz es equivalente al peso del automóvil. El área del pistón ( $A$ ), medido en metros cuadrados, es determinado por:

$A=\frac{\pi}{4}\cdot D^{2}$

Donde $D$ es el diámetro del pistón, medido en metros.

Si $D = 0.32\,m$ y $F =17,640\,N$ , entonces la presión neumática es:

$A = \frac{\pi}{4}\cdot (0.32\,m)^{2}$

$A \approx 0.080\,m^{2}$

$P = \frac{17,640\,N}{0.080\,m^{2}}$

$P = 220,500\,Pa$

La presión neumática para levantar un automóvil de 17,640 newtons es 220,500 pascales.

The speed of a sound wave

hammer [34]

I think the correct answer from the choices listed above is the first option. The speed of a sound wave is slower than an electromagnetic wave or light waves are faster than sound waves. Hope this answers the question. Have a nice day.
