Density: 1.9 g/cm3
density = mass/volume
d = 5.7/3
d = 1.9
Explanation:
Displacement=Velocity×time
=24.7×16.00
=395.2m
Therefore the displacement within the time interval is 395.2m
Thermal equilibrium is a state in which all parts of a system are at the same temperature
Acceleration occurs when there is a change in speed or direction. If it travels in a straight line, there is no speed or change in direction as it is constant througout, hence 0 acceleration.

Answer:
The minimum power neccesary is:
Explanation:
The water is bring to a boil so it goes from 25°C to 100°C, the temperature rise si:
Considering that the cup is always at the same temperatura as the water the trasfered energy can be calculated as:
We have that:
So:
Given that this energy was supplied in 2 minutes:
The minimum power neccesary is:
