SashulF [63]3 years ago

Answer:

Explanation:

When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the object

which means that it refers to transfer through a selectively permeable partition, the contact path.[1] For the relation of thermal equilibrium, the contact path is permeable only to heat; it does not permit the passage of matter or work; it is called a diathermal connection. According to Lieb and Yngvason, the essential meaning of the relation of thermal equilibrium includes that it is reflexive and symmetric. It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms

plz dont be mad that i coppied it sounded so good so i wanted veryone to see it when they look bc i am dumb

inn [45]

Answer:

Explanation:

average speed is distance traveled over time

v = (50 + 30(1.5)) / (2 + 1.5) = 27.1428571...

v = 27 km/hr

A 30 g mass is attached to one end of a 10-cm-long spring.
Usimov [2.4K]

The value of the spring constant of the spring is 14.7 N/m.

The given parameters;

  • <em>mass attached to the spring, m = 30 g</em>
  • <em>length of the spring, L₀ = 10 cm</em>
  • <em>angular speed of the mass = 90 rpm</em>
  • <em>final length of the spring, L₁ = 12 cm</em>

The extension of the spring is calculated as follows;

\Delta x = L_1 - L_0\\\\\Delta x = 12 \ cm - \ 10 \ cm\\\\\Delta x = 2 \ cm = 0.02  \ m

The value of the spring constant of the spring is calculated by applying Hooke's law;

F = mg = k\Delta x\\\\k = \frac{mg}{\Delta x } \\\\k = \frac{0.03 \times 9.8}{0.02} \\\\k = 14.7 \ N/m

The density of water is 1.00 g/mL. This means if a rock has a density of 0.87 g/mL, it will ____in water.
Vilka [71]

Answer:

Float

Explanation:

It is given that,

The density of water is 1 g/mL

The density of a rock is 0.87 g/mL

It can be seen that the density of water is more than that of rock. The density of an object is calculated from its mass and volume.

If the density of liquid in which it is placed, is more that that of the object, it will float at the top.

Hence, in this case the rock will float.
