To solve this problem we will use the concepts related to thermal expansion in a body for which the initial length, the coefficient of thermal expansion and the temperature change are related:
Where,
= Change in Length
= Coefficient of linear expansion
= Change in temperature
= Initial Length
Our values are:
Replacing we have,
Therefore the change in milimiters was 0.4126mm
John's truck has more mass than his brother Thomas' truck.
John's truck has more inertia than Thomas' truck.
If both trucks get equal force, John's truck will accelerate more slowly than Thomas' truck.
John's truck needs more force to accelerate.
If both trucks are just sitting there, John's truck needs more force to start moving.
We don't know anything about the efficiency of either truck. Or the efficiency of either brother, for that matter.
30 km/h * 17 h = 30*17 km/h *h
= 510 km
You are observing the boiling point
The awnser is: at t = 4 seconds (B).
