Answer:
Required heat q = 0.8372 j
Explanation:
Given:
Specific heat of water = 4.186 J g-1 °C-1
Mass m = 10 g = 0.01 kg
Temperature t = 20.00 °C
Find:
Required heat q
Computation:
q = cmΔT
Required heat q = [4.186][0.01][20]

Good luck
E. and .
According to the figure, we have the following conclusions:
1) and are vertical opposite angles. ()
2) and are internal alternate angles. ()
3) and are corresponding angles. ()
4) and are vertical opposite angles. ()
But, and , since , where is an acute angle and is a right angle, and . Then,
.
Hence, the right answer is E.
