Se necesita fuerza continua para el movimiento continuo?

Physics

zhenek [66]3 years ago

¿Se necesita fuerza continua para un movimiento continuo? No exactamente, ya que la fuerza que se aplica para mantener un objeto en movimiento solo se usa para que la fuerza de fricción pueda ser contrarrestada. Si un astronauta arrojara, digamos, una computadora portátil al espacio durante una caminata espacial (por qué arrojar una tableta perfectamente buena en el esquema interminable del cosmos, no lo sé), viajaría con una velocidad constante para siempre, a menos que golpea algo También podría reemplazar la computadora portátil con Voyager 2, que se mantuvo en movimiento y ahora está fuera de nuestro sistema solar. Esto se debe a que el espacio está mayormente vacío y no habría ninguna fuerza de fricción que actúe sobre esa roca. A menos que sea golpeado por un asteriodo o algo así, lo que haría una pregunta física diferente.

Espero que esto ayude, ¡TENGA UN DÍA BENDITO Y MARAVILLOSO! ¡Y un gran fin de semana de Superbowl! :-)

marysya [2.9K]

Answer:

449.38 J

Explanation:

ΔS = ΔQ/T

Where ΔS = entropy change

Q = quantity of heat

T = temperature

First reservoir :

T = –30°C = - 30 + 273 = 243K

Q = 400 J

Second reservoir :

T = 0°C = 273K

Q =?

To have same increase in entropy for both reservoirs :

Q/T of first reservoir = Q/T of second reservoir

400/243 = Q/273

243 * Q = 400 * 273

Q = (400 * 273) / 243

Q = 109,200 / 243

Q = 449.38271

Q = 449.38 J

True [87]

Answer:

35.489km

Explanation:

a diagram illustrating the question is attached

now, applying cosine rule to find the displacement c

cosine rule;

c²=a²+b²-2abCos ∅

c²=50²+80²-2(50)(80)Cos 38°

c²=2500 + 6400 - (8000×0.9951)

c²=8900-7640.589

c²=1259.411

c=\sqrt{1259.411}

c=35.49km
