the force of attraction of iron fillings towards magnet
Answer:
Q = 8.68 × 10⁴ J
Explanation:
We can calculate the heat required to melt a mass of ice, that is, to change it from the solid phase to the liquid phase, at a constant temperature of 0 °C, using the following expression.
Q = ΔH°f × m
where,
- ΔH°f is the standard enthalpy of fusion (ΔH°f for water: 334 J/g)
Q = ΔH°f × m
Q = 334 J/g × 260 g
Q = 8.68 × 10⁴ J
Answer: Last week, he accidentally dropped his coffee mug, which then fell on the floor due to gravity.
A scientific law can be defined as a law which followed universally. As a scientific law gives evidences and facts related to a natural phenomena. It is useful in scientific education and research.
Last week, he accidentally dropped his coffee mug, which then fell on the floor due to gravity is an example of law of gravity. The law of gravity states that objects are attracted to each other due to the magnitude of force acting between these objects. The earth exerts it's own gravitational force, to attract the objects towards itself.
