There is no picture to reference from so I’m going to take a wild guess and say A
The amount of heat needed to raise the temperature of a 2kg object from 15°C to 25°C is 34000J.
HOW TO CALCULATE SPECIFIC HEAT CAPACITY:
- The amount of heat absorbed by an object can be calculated by using the following expression:
Where;
- Q = amount of heat absorbed or released (J)
- m = mass of object
- c = specific heat capacity (J/g°C)
- ∆T = change in temperature (°C)
- According to this question, 2 kg object has a specific heat capacity of 1,700J/kg°C and was raised from a temperature of 15 Celsius to 25 Celsius. The heat absorbed is calculated as follows:
- Therefore, the amount of heat needed to raise the temperature of a 2kg object from 15°C to 25°C is 34000J.

Answer:
<h2>C</h2>
Explanation:
2.0 × 10^3 is the correct form for writing any term in scientific notation form.
Comment for understanding anything.
The answer is C. nebular are star nurseries. When the massive gas being collapsing in its own weight. Local areas of gas begin to coalesce under gravity. Due to enormous pressure, nuclear fusion begins and a protostar is formed. The protostar grows into the sun as more hydrogen fuses at the core. The planetesimal materials at the edges of the protostellar discs coalesce to form planets that orbit the star.
95 degrees Fahrenheit in Celsius scale is 35 degrees Celsius
