Answer:
Mike can travel 80 Km in 4 hours
Answer:
170⁰C
Explanation:
α= ΔL/(lo×Δt)
arranging for Δt
Δt =ΔL/(lo×α)
here Δt is change in temperature, ΔL is change in length,lo is original length and is α coefficient of linear expansion and for copper its value is 17×10^-6
Δt =(0.00130)/(0.450×17×10^-6)
Δt=169.9⁰C
Δt= 170⁰C
The answer is A. Natural selection always favors individuals in a population that are well adapted to their environment. These individuals are able to get to maturity and pass down their genes to subsequent generations. Any disadvantages mutations in the population are eliminated by natural selection.
