Responder:
39200 J
Explicación:
Dado:
Masa de Tamara (m) = 50 kg
Altura a la que se encuentra Tamara (h) = 80 m
Aceleración debido a la gravedad (g) = 9.8 m / s²
La energía potencial de un objeto de masa 'm' ubicada a una altura 'h' sobre el suelo se da como:
Ahora, conecte los valores dados y resuelva la energía potencial. Esto da,
Por lo tanto, la energía potencial de Tamara ubicada a una altura de 80 m es 39200 J.
Answer:
True
Explanation:
Golden Rice is an example of genetically modified organism.
In physical chemistry, the mean free path is the average distance between the atoms during collision. Its formula is
where d is the diameter of the Nitrogen atom (d = 310 x 10^-7 m), Na is Avogadro's number (Na=6.022 x 10^23), R is the gas constant (8.314 J/mol-K), T is the absolute temperature (T= 20 + 273 = 293 K). Substituting the values,
P = 6.32 x 10^-13 Pascals
it's Also called aerobic exercise, endurance exercise includes activities that increase your breathing and heart rate such as walking, jogging, swimming, and biking. Endurance activity keeps your heart, lungs and circulatory system healthy and improves your overall fitness.
I see you're in Middle School, so I've got a hunch that they want you
to say "the dresser because it has more mass". But that's a poor
answer, to a poor question.
The fact is that there's no way to tell.
The force it takes to move either object across the floor does NOT really
depend on just its mass. It depends on both the object's mass AND the
friction between the object and the floor. And THAT depends on the shape
of the feet where they touch the floor, and what kind of material the feet and
the floor are made of.
So it seems to me that we really don't have enough information to answer
the question with.
But again, I suspect that the answer they want is "the dresser because
it has more mass".
