Ahora, la potencia media es el resultado anterior dividido por el tiempo. Se despeja el tiempo de la ecuación:
La opción más aproximada es D.
Answer:
i don't really know the exact answer but i would say something like earthquakes or steam/excessive heat
Explanation:
Answer:
Increase
Explanation:
If we assume the gas is ideal, then we can use the ideal gas law:
PV = nRT
If V is held constant while P increases, then T will also increase.
Answer:
Explanation:
In order to answer this question, we simply have to refer to the laws of the equations of gravitational mechanics.
The equation given by Newton tells us that
In the case where we compare a specific place where the Force of Gravity is greater or lesser, we focus on the term assigned to the Planet's Radius.
In the case of , we understand that they are constant.
We can easily notice that the more the Radius (Height seen from a viewer on the ground), the lower the force will be.
In other words, the smaller the radius in which the measurement is made with respect to the center of the earth, the greater the gravitational force.
In that order of ideas the smallest radio has South Pole, which is about 6356 km from the center of the Earth on the Equator line
Answer:
Temperature of parcel at 1000 ft is 85.5°F
Explanation:
Temperature of parcel at 0 ft =T₁ = 91.0°F
Dry adiabatic rate = 5.5°F/100 ft
Temperature of parcel at H₂ (1000 ft) = T₂ =?
Height of LCL = 5000 ft
As (1000<5000), so using the formula for parcel below or at the LCL i.e.
