Answer:
True! First step is to make objective observations.
Answer: 10.2 kg if g = 9.8, 10 if g = 10.
Explanation:
Weight or the "force of gravity" on a person is simply defined by the equation: F = ma. In this case, the acceleration is g, which is 9.8 but can be rounded up to 10. Based on this, we have:
F = mg
100 = m*9.8
m = 10.2(or 10 if we set g to 10).
Answer:
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed= Joules
m= mass of copper = 454 g
c = specific heat capacity =
Initial temperature of the copper = = 23.0°C
Final temperature of the water = = ?
Change in temperature ,
Putting in the values, we get:
The final temperature of copper will be
