Answer:
a) El valor de la densidad es 0.79 
o 790
b) El peso especifico es 7749.9
Explanation:
a) La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:
En este caso:
- masa= 237 g= 0,237 kg (siendo 1000 g= 1 kg)
- volumen= 300 cm³= 0,0003 m³ (siendo 1 cm³= 0,000001 m³)
Reemplazando:
→ d=0.79
→ d=790
<u><em>El valor de la densidad es 0.79 </em></u><u><em> o 790 </em></u><u><em></em></u>
b) El peso específico es la relación existente entre el peso y el volumen que ocupa una sustancia en el espacio.
Entonces, en este caso, siendo el peso:
P= m*g= 0,237 kg* 9,81 
= 2,32497 N
el peso especifico es calculado como:
Pe= 7749.9
<u><em>El peso especifico es 7749.9</em></u><u><em></em></u>
Answer:
<h2>Ohh your photo is blurd </h2>
Explanation:
<h2>Ohh your photo is blurd </h2>
A. the gas particles move faster and collide more frequently, which causes an increase in pressure.
Increasing temperature increases the energy of the gas, which causes the kinetic energy of the molecules to increase.
The complex, highly technical formula for capacitors is
<em>Q = C V</em>
Charge = (capacitance) (voltage)
Charge = (3 F) (24 V)
<em>Charge = 72 Coulombs</em>
The positive plate of the capacitor is missing 72 coulombs worth of electrons. They were sucked into positive terminal of the battery stack.
The negative plate of the capacitor has 72 coulombs worth of extra electrons. They came from the negative terminal of the battery stack.
You should be aware that this is a humongous amount of charge ! An average <u><em>lightning bolt</em></u>, where electrons flow between a cloud and the ground for a short time, is estimated to transfer around <u><em>15 coulombs</em></u> of charge !
The scenario in the question involves a "supercapacitor". 3 F is is no ordinary component ... One distributor I checked lists one of these that's able to stand 24 volts on it, but that product costs $35 apiece, you have to order at least 100 of them at a time, and they take 2 weeks to get.
Also, IF you can charge this animal to 24 volts, it will hold 864J of energy. You'd probably have a hard time accomplishing this task with a bag of leftover AA batteries.
