Answer:
The reason is because both are exposed to a virtually infinite heat sink, due to the virtually infinite mass and of the surrounding environment, compared to the sizes of either the cup or the kettle such that the equilibrium temperature, reached is the same for both the cup and the kettle as given by the relation;
Due to the large heat sink, T₂ - T₁ ≈ 0 such that the temperature of the kettle and that of the cup will both cool to the temperature of the environment
Explanation:
From the diagram we have that
Therefore the direction is 30° from east of south
Answer:
It will remain same i.e. 4.0 Hz
Explanation:
In a mass-and-spring system, the frequency depends upon the mass (m) and the spring constant (k).
Since, the frequency does not depend on the initial displacement of the mass, the frequency would remain the same i.e. 4.0 Hz.
