Answer:
The temperature of the metal is 
Explanation:
From the question we are told that
The mass of the metal is 
The specific heat of the metal is 
The mass of the oil is 
The temperature of the oil is 
The specific heat of oil is 
The equilibrium temperature is 
According to the law of energy conservation
Heat lost by metal = heat gained by the oil
So
The quantity of heat lost by the metal is mathematically represented as
=> 
Where 
the temperature of metal before immersion
The negative sign show heat lost
The quantity of gained t by the metal is mathematically represented as
=> 
So
substituting values
=>
Answer:
Third → First → Second → Fourth
Explanation:
Initially helium and Hydrogen in abundance started to form atoms
Following the atoms formation by hydrogen and helium bombardment of new matter into the Earth took place.
The bombardment of matter resulted in separation of Earth into respective layers based on the weight of the matter.
A primitive ocean was created as a result of off gassing of the volcanoes.
To solve this problem it is necessary to apply the concepts related to Newton's second Law and its definition of density.
By Newton's second law we understand that,
F = ma
Where,
m = mass
a = acceleration (at this case the gravity acceleration)
In the case of density, we know that it is described as the proportion of mass versus volume, that is,
Where,
m = mass
V = Volume
The total tension of the AB cable would be given by the tension exerted upwards by the water and the tension exerted by the weight, therefore,
Mass can be expressed as,
Therefore the tension in cable AB is 6103.94N
For CO2 we know that it has a useful life in the atmosphere of the earth, sometimes long. Carbon dioxide has the ability to absorb energy with a wavelength of 15 µm, this makes carbon dioxide a good absorbent of wavelengths that are in this range, such as infrared radiation for example .
At the same time the water vapor has the capacity to absorb the radiation in a 50 µm and 2.9 µm spectrum, infrared radiation fluctuates over the same range.
Therefore the correct answer is A.
