The electron dot structure would look like this :
Answer: The specific heat capacity of metal is
Explanation:
As we know that,
where,
= mass of metal = 35 g
= mass of water = 220 g
= final temperature =
= temperature of metal =
= temperature of water =
= specific heat of metal = ?
= specific heat of water =
Now put all the given values in equation (1), we get
Therefore, the specific heat capacity of metal is
1. take 20 * 0.5 to get 10 m/s
2. 0.8/0.4 = 2 Hz
I guess A is the correct answer
