The temperature of a 2.0 kg block increases by 5 0c when 2,000 j of thermal energy are added to the block. What is the block's s
1 answer:
Mass of the block = 2 kg
Temperature is increased by ΔT = 50 °C
Energy consumed by the block in raising the temperature = 2000 Joules
Let the specific heat capacity of the block be "c".
Formula to be used:
Heat gained = m × c × ΔT
Plugging the values:
2000 = 2 × c × 50
c = 20 J/ kg °C
Hence, the specific heat capacity of the block is: 20 J/ kg °C

Explanation:
- In a RC circuit we call time constant to the product of the resistance times the capacitance, which represents the time when the charge reaches to the 63% of the final value, as follows:
- If we have a new circuit with new values for R and C, the time constant will be defined in the same way, as follows:
