Answer:

Los movimientos verticales o circulación convectiva consisten en un intercambio de lugar entre el aire caliente de las capas bajas y el aire frío de las superiores. Este movimiento se debe a la diferencia de densidades de las distintas masas de aire. Los movimientos horizontales se basan en las diferencias de presión.

Answer:

el movimiento vertical está cambiando, pero el movimiento horizontal es constante (suponiendo que no haya fuerza de fricción de la resistencia del aire). ... Sin fricción significa que no hay fuerza en la dirección opuesta.

navik [9.2K]

Answer:

Explanation:

height lost h = 300 sin60

= 259.8 m .

gravitational potential energy = mgh

= 5000 x 9.8 x 259.8

= 1273 x 10⁴ J

Kinetic energy

= 1/2 mv²

= .5 x 5000 x 60²

= 900 x 10⁴ J

there is loss of kinetic energy = 373 x 10⁴ J.

This loss in energy is due to kinetic friction that came into action when the sled slipped downwards.

The lost energy is converted into heat energy or thermal energy.

The Pacific Plate is moving 29 mm/year toward the north and 20 mm/year toward the west relative to the North American Plate. Sho

adell [148]

Answer:

7 mm per year

Explanation:

It is given that :

The Pacific plate is moving towards north at = 29 mm per year

The Pacific plate is moving towards west at = 20 mm per year

We have to calculate the total relative motion towards the northwest.

So we have to find the resultant of the two motions.

Since the two movements are perpendicular, therefore the angle between the two motions is 90 degree.

Therefore, finding their resultant,

$R^2=(29)^2+(20)^2$

$R^2=(49)^2$

R = 7

Therefore, total relative motion towards the northwest is 7 mm per year.

The latent heat of vaporization for ethyl alcohol is 854 J/g. The amount of energy, rounded to the nearest whole number, needed

Lorico [155]

Answer:

4441 J

Explanation:

The amount of energy needed to change the ethyl alcohol from liquid to gas state is given by

$Q=m \lambda_v$

where

m = 5.20 g is the mass of the alcohol

$\lambda_v = 854 J/g$ is the latent heat of vaporization of the substance

Substituting the numbers into the formula, we find:

$Q=(5.20 g)(854 J/g)=4,441 J$
