Answer:
μ = 0.136
Explanation:
given,
velocity of the car = 20 m/s
radius of the track = 300 m
mass of the car = 2000 kg
centrifugal force
F c = 2666. 67 N
F f= μ N
F f = μ m g
2666.67 = μ × 2000 × 9.8
μ = 0.136
so, the minimum coefficient of friction between road surface and car tyre is equal to μ = 0.136
The first one and the second i’m glad to help
Answer:
A. Bow
Explanation:
Registration number is an evidence or authentication of registration of a vessel or vehicle. This number is very important when an emergency occurs and there is a need to trace the vessel to the owner. And this should be displayed on a vertical surface or a surface where easy view is achievable.
So it is recommended that registration numbers be displayed on the bow of the vessel. The number should be displayed in such a way that it could be read from left to right.
An architectural engineer is a person who is responsible for studying and evaluating construction blueprints and designs. This is to determine if the design is feasible and if it is feasible to construct. Building styles and aesthetics should not be prioritized over the structural integrity and safety of a proposed building. Plan, construct, and prototype buildings, and be able to identify, analyze, and resolve issues with them as they arise.
