According to Charles law, if pressure remains constant, volume varies directly with temperature. so we can infer that :
So, we can use this formula to find out the final temperature of the gas ~
Note : Take temperature in Kelvin ( 100°C = 373 K )
Now, convert it to Celsius ~
i.e 746 - 273 = 473° C
So, the final temperature of the gas will be equal to 473° C
Answer:
a) 4.94e9 J b) 1.07e10 J
Explanation:
The electric potential energy stored in a capacitor, expressed in terms of the value of the capacitance C, and the voltage between its terminals V, is as follows:
a) For the original capacitor, we can find directly U as follows:
U = 4.94*10⁹ J
b) Prior to find the electric potential energy of the upgraded capacitor, we need to find out the value of the capacitance C of this capacitor, which is identical to the original, except that has a different dielectric constant.
As the capacitance is proportional to the dielectric constant, we can write the following proportion:
ε₂ / ε₁ =
Once calculated the new value of the capacitance, as V remains the same, we can find the electric potential energy for the upgraded capacitor as follows:
⇒ U = 1.07*10¹⁰ J
Answer:
Explanation:
Given that,
Mass of the car,
Initial speed of the car,
Final speed of the car,
To find,
The maximum mass of grain that it can accept.
Solution,
We know that according to the law of conservation of momentum, the initial momentum is equal to the final momentum.
Therefore, the maximum mass of grain that it can accept is 2554.83 kg. Hence, this is the required solution.
