Answer:
3.5 K
Explanation:
When a sample of a substance releases heat energy, its temperature decreases according to the equation:
where
Q is the heat energy released
m is the mass of the substance
C is the specific heat capacity
is the initial temperature
is the final temperature
For the block of brass in this problem, we have:
m = 0.1 kg is the mass
Q = -56.4 J is the heat energy released (negative since it is released)
C = 380 J/kg K is the specific heat capacity of brass
is the initial temperature
Solving for , we find the final temperature:
Answer:
Explanation:
D)The system is open, and the net external force is nonzero.
John is a B.passionate criminal because he lies just for the heck of it. Hope i helped.
Option B is correct. (4 + 2i)(3 – 5i) = (3 – 5i)(4 + 2i) satisfies the commutative property of multiplication
Given two values A and B, according to the commutative property of multiplication;
This shows that the product of A and B stays the same no matter the arrangement.
From the given option, we can see that (4 + 2i)(3 – 5i) = (3 – 5i)(4 + 2i) satisfies the commutative property of multiplication where we can say;
A = 4 + 2i and B = 3 - 5i
