Answer:
Change in entropy S = 0.061
Second law of thermodynamics is satisfied since there is an increase in entropy
Explanation:
Heat Q = 300 kW
T2 = 24°C = 297 K
T1 = 7°C = 280 K
Change in entropy =
S = Q(1/T1 - 1/T2)
= 300(1/280 - 1/297) = 0.061
There is a positive increase in entropy so the second law is satisfied.
1. Renewable Resources = (Renewable means you can keep making it) = resources that can be replenished (such as trees)
2. Nonrenewable Resources = ( Nonrenewable means it can't be made once it is used up) = resources that are gone once they are used (such as fossil fuels)
3. Producer = ( produces something) = person who makes goods or provides services
4. Consumer = ( uses something) = person whose wants are satisfied by using goods and services
5. Allocate = ( put someplace) = distribute
6. Choice = option

Answer
given,
a = 2 t - 10
velocity function
we know,


integrating both side

v = t² - 10 t + C
at t = 0 v = 3
so, 3 = 0 - 0 + C
C = 3
Velocity function is equal to v = t² - 10 t + 3
Again we know,


integrating both side


now, at t= 0 s = -4

C = -4
So,

Position function is equal to
