Answer: 0.9
Explanation:
For an inclined surface the coefficient of friction (n) is the ratio of the moving force (Fm) to the normal reaction (R) acting on the body.
n = Fm/R
Fm = WSintheta = mgsintheta
R = Wcostheta = mgcostheta
n = Wsintheta/Wcostheta
n = sintheta/costheta
n = tan theta
n = tan 42°
n = 0.9
Therefore, minimum coefficient of static friction between the vehicle’s tires and the road is 0.9
The formula for potential energy is mass x height x gravitational force. Your mass is 5.3 kg and your height is 6.6 meters. The gravitational force on earth is 9.8 m/s. That means your answer is 5.3 x 6.6 x 9.8 and that equals 342.804
Answer:
The answer is D.
Explanation:
An example of a weak base is ammonia. It does not contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. The position of equilibrium varies from base to base when a weak base reacts with water. The further to the left it is, the weaker the base.
