Answer:
C
Explanation:
When A and B come in contact with each other, +12 - 12 = 0 so their changes cancel.
Now C has a charge of +12
When A and C come together they each have an equal share of that 12, so each of them has 6
So the answer is
A B C
6 0 6
which is C
Answer:
Explanation:
When an amount of energy Q is supplied to a substance of mass m, the temperature of the substance increases by 
, according to the equation
where 
is the specific heat capacity of the substance.
In this problem, we have:
is the amount of heat supplied to the sample of gold
m = 0.1 kg = 100 g is the mass of the sample
is the specific heat capacity of gold
Solving for , we find the change in temperature
And since the final temperature was
The initial temperature was
The maximum velocity reached by the person is determined as 11.1 m/s.
<h3>Area under velocity - time graph</h3>
The area under the velocity time graph is the total displacement of the person.
Total Area = area of triangle formed during first 2 seconds + area of rectangle during the last 8 seconds
100 = ¹/₂(2v) + v(11 - 2)
where;
- v is the maximum velocity
100 = v + 8v
100 = 9v
v = 100/9
v = 11. 1 m/s
Thus, the maximum velocity reached by the person is determined as 11.1 m/s.
