Answer:
The heat is 10458 J and 15480 J.
Explanation:
Given that,
Temperature T₁ = 404 K
Temperature T₂ = 298 K
Work done = 2740 J
If the temperature T₁ =298 k
Temperature T₂ = 245 K
We need to calculate the heat
Using efficiency formula
...(I)
We need to calculate the efficiency
Using formula of efficiency
Put the value of efficiency in equation (I)
Again, we need to calculate the efficiency
We need to calculate the heat
Using equation (I)
Hence, The heat is 10458 J and 15480 J.
From the information in the question, the velocity of the particle is 24 ms-1.
Let us recall that the velocity of a body is obtained as the first derivative of distance covered with respect to time. Hence;
ds/dt = v
Now, we have to differentiate (t^3- 3t^2 + 2)m with respect to t and we have;
d(t^3- 3t^2 + 2)m/dt = 3t^2 - 6t
Now at t= 4s, the velocity of the particle is;
3(4)^2 - 6(4) = 24 m/s
The acceleration of the particle is the second derivative of distance with respect to time;
d^2s/dt^2 = d^2 3t^2 - 6t/dt^2 = 6t
Substituting t = 4s
a = 24 ms-2
