Making changes in the dna of organism is called mutation
Answer:
3.5 K
Explanation:
When a sample of a substance releases heat energy, its temperature decreases according to the equation:
![Q=mC(T_f-T_i)](https://tex.z-dn.net/?f=Q%3DmC%28T_f-T_i%29)
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:
![T_f=T_i + \frac{Q}{mC}=5+\frac{-56.4}{(0.1)(380)}=3.5 K](https://tex.z-dn.net/?f=T_f%3DT_i%20%2B%20%5Cfrac%7BQ%7D%7BmC%7D%3D5%2B%5Cfrac%7B-56.4%7D%7B%280.1%29%28380%29%7D%3D3.5%20K)
Answer: Ture. It satisfies Utilitarian needs
Explanation:
Utilitarian needs are our basic needs or those needs that either make our lives better if they were to be satisfied.
They can be satisfied by buying products that satisfy our basic needs as well as products of great quality with cheaper pricing, offer us variety and/or give us more convenience.
The washer and dryer that Marco is going to buy will give him more convenience which means that it is satisfying a Utilitarian needs.
