I racked my brain for almost 10 minutes, until suddenly,
it hit me !
You're breathing one right now ! So am I .
Air is a mixture of a lot of elements.
Nitrogen, Oxygen, and Argon account for 99.964 percent.
The other 0.036 percent is mainly Neon, Helium, Krypton,
and Hydrogen ... more elements.
Then there are Carbon Dioxide and water vapor.
Yes, those are compounds. But together, they add up
to very little of the air we breathe, and if both of them
suddenly disappeared, we would hardly notice it.
Answer:
First Condition of Equilibrium
For an object to be in equilibrium, it must be experiencing no acceleration. This means that both the net force and the net torque on the object must be zero. Here we will discuss the first condition, that of zero net force. ... Fnet=0 F net = 0.
Responder:
- Volumen del bloque = 60cm³
- Densidad = 5g / cm³
Explicación:
Dada la dimensión del bloque
AB = 4 cm, BC = 2.5 cm y BF = 6 cm
Volumen del bloque = Largo × Ancho × Alto
Volumen del bloque = AB × BC × BF
Volumen del bloque = 4 × 2.5 × 6
Volumen del bloque = 60cm³
Dada la masa del bloque = 300 gramos
Densidad = Masa / Volumen
Densidad = 300g / 60cm³
Densidad = 5g / cm³
Algunos materiales que tienen una densidad de 5g / cm³ o cercanos son radio, germanio y europio con densidades de 5g / cm³, 5.3g / cm³ y 5.24g / cm³ respectivamente.
