I think jogging/running/walking because you don't need any equipment and you can structure around it on your own time.
The characteristics of thermal expansion allow finding that the response for a material without thermal expansion is
- The length variation is zero
- In the graph the line is horizontal so there is no change in length with temperature
Thermal expansion is the macroscopic sum of the changes in the length of the bonds when the energy (temperature) changes, it can be written
ΔL = α L₀ ΔT
Where ΔL is the change in length, α the coefficient of linear expansion, L₀ the initial length and ΔT the change in body temperature
In this case, a material is being designed that the thermal expansion is very small, for this the material must be made up of several compounds where some of them present a contraction with temperature, some examples: water at low temperature, liquefied gases , ceramic tile, quartz, etc.
The thermal expansion measurement processes control the body temperature and measure the change in length, in this case the change in length must be zero, in the attachment we can see a graph of a composite material with these characteristics, an example of this type of material is Invar an alloy of nickel and iron α = 3.7 10⁻⁶ ºC⁻¹
In conclusion, using the characteristics of thermal expansion we can find that the response of material without thermal expansion is
- The length variation is zero
- In the graph the line is horizontal so there is no change in length with temperature

The correct answer is c.
work is calculated by force * distance less force means less work there its self explanatory c
Answer:add resistance in the parallel circuit with the total resistance
Explanation:
the total resistance in the parallel circuit is also add resistance.
Answer:
Explanation:The rate of decrease of velocity is given with respect to displacement. As v approaches zero when s approaches 39, it can be written as
where c=19
when s=8 we have
hence a can be found by the chain rule
From the equation
the s in term of t can be found
Hence it can be seen that if s approaches 39 the t function becomes undefined hence s is never 39m
