Answer:
This is the question related to physics.
Explanation:
Reflection is the bouncing back of light from any surface
whereas
Refraction is the passing of light from one medium to another medium. Here light get bent to certain angle while passing from one medium to another.
Answer:
When your graphing to data from an experiment.
Explanation:
You use any type of graph when you're doing an experiment because, in the beginning, you start by marking where you started then as time goes on you mark it accordingly. For example, say your starting at 5cm on a plant so on the line/bar graph you make 0 you 5 since that is where you're starting at. when you water the plant you decide to give it 10cm of water and put it in the sun constantly. A week later of sun and water it grew 10cm, so you mark it on your line/bar graph to show how much it grew over time. Make a little bit more sense?

Initially you need to find the specific heat of the granite. It is found in tables.
With that data, you can apply the equation: Q = m * C * ΔT
Where:
m = 17 kg
ΔT = 45°C - 21°C = 24 °C
And, from a table the specific heat, C, of granite is 790 J/kg°C
Therefore, you get: 17 kg * 790 J/kg°C * (24°C) = 332,320
This answer is pretty close to the option A, and you can conclude that the difference is due a small difference in the specific heat used.
Answer: option A.
