Answer:
64.85 m
Explanation:
a)
μ = Coefficient of friction between road and tire on rainy day = 0.107
g = acceleration due to gravity = 9.8 m/s²
a = acceleration experienced by car due to friction = - μg = - (0.107) (9.8) = - 1.05 m/s²
v₀ = initial velocity of the car = 42 km/h = 11.67 m/s
v = final speed of the car = 0 m/s
d = minimum distance traveled before stopping
Using the equation
v² = v₀² + 2 a d
0² = 11.67² + 2 (- 1.05) d
d = 64.85 m
<span>The correct answer is option C i.e. chemical change. When bonds between atoms are broken or new bonds are formed, the outcome is the change in chemical structure or some other type of chemical changes take place.</span>
Because of the enormous expense of creating conditions aboard
a spacecraft in which astronauts can survive, and the huge extra
weight and expense of guaranteeing their safety.
