Answer:
c = 0.38 J/g °C
Step-by-step explanation:
We have,
Mass of metal X is 95.4 g
Initial temperature was 25°C and final temperature is 48°C.
The metal absorbs 849 J of heat
The heat absorbed due to change in temperature is given by :
So, the specific heat of metal X is 0.38 J/g °C.
<span><u><em>Answer:</em></u>
The first group would have <u>12 cans</u>
The second group would have <u>16 cans</u>
<u><em>Explanation:</em></u>
We know that the total number of cans in 28 and that the ratio between the two groups is 3:4
<u>This means that:</u>
If the first group has 3x cans, then the second group would have 4x cans.
<u>Now, we would solve for x:</u>
3x + 4x = 28
7x = 28
x = </span>
<span>
x = 4 cans
<u><em>Therefore:</em></u>
The first group would have 3x = 3(4) = 12 cans
The second group would have 4x = 4(4) = 16 cans
Hope this helps :)</span>
