General Physics Question:
When a bar of iron is heated, it expands. What will happen to its weight when it is heated?
Answer:
the weight remains the same as weight depends on mass and
acceleration due to gravity
W = m * g
as mass does not change and acceleration due to gravity does
not change so weight remains same
acceleration due to gravity
W = m * g
as mass does not change and acceleration due to gravity does
not change so weight remains same
