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

Answer:
500Km
Explanation:
This question is an example of speed, distance, time.
The formula for working out the distance is:
To work this out you would need to multiply the speed of 200Km/h by the time of 2.5 hours, this gives you 500 Km. This is because the formula to work out the distance is speed * time.
In adittion, if the train is traveling at 200km per hour then that means that over the course of an hour the distance travelled would be 200Km. So, by multiplying the speed by the time you are working out how far it travelled in that given time.
1) Multiply 200 by 2.5.
