Answer:
a = - 0.248 m/s²
Explanation:
Frictional drag force
F = ½ *(ρ* v² * A * α)
ρ = density of air , ρ = 1.295 kg/m^3
α = drag coef , α = 0.250
v = 100 km/h x 1000m / 3600s
v = 27.77 m/s
A = 2.20m^2
So replacing numeric in the initial equation
F = ½ (1.295kg/m^3)(27.77m/s)²(2.30m^2)(0.26)
F = 298.6 N
Now knowing the force can find the acceleration
a = - F / m
a = - 298.6 N / 1200 kg
a = - 0.248 m/s²
In a nuclear<span>-fueled </span>power plant<span> – much like a fossil-fueled </span>power plant<span> – water is</span>turned<span> into steam, which in turn drives turbine generators to produce </span>electricity<span>. The difference is the source of heat. At </span>nuclear power plants<span>, the heat to make the steam is created when uranium atoms split – called fission.</span>
