A chandelier is suspended by two identical, vertical chains side by side. The chandelier's mass is m = 6.5 kg. Part (a) If the t
Alja [10]

Answer:

a)T= mg/2

b) T = 31. 88 N

c)Tension will increase

Explanation:

Given that m= 6.5 Kg

a)

The force due to gravity = m g

The tension in the chain = T

The total tension = 2 T

By balancing force in vertical direction

2 T = m g

T= mg/2

b)

2 T = m g

2 x T = 6.5 x 9.81

T = 31. 88 N

c)

Lets take angle made by chain is θ

So the total tension in vertical direction = 2 T cos θ

2 T cos θ = m g

T= mg/(2cos θ)

It means that tension will increase because cos θ is always less than 1.

A volume of cool air rapidly descends from the top of a mountain. The air is a poor thermal conductor, but its temperature incre
kolbaska11 [484]

Answer:

Adiabatic

Explanation:

An adiabatic process is a thermodynamic process in which the system does not exchange heat with its surroundings. An adiabatic process may also be isentropic, meaning that the process may be reversible. The term adiabatic refers to elements that prevent heat transfer with the environment. An insulated wall is quite close to an adiabatic boundary. Hence the term of the adiabatic wall appears.

Air is a bad thermal conductor, this means that air is a system that makes it difficult to change the temperature with the systems around it, so we can conclude that the above question deals with the thermodynamic process called adiabatic.
