Electromagnetic waves are usually transverse waves whilst sound wave are longitudinal waves. Furthermore, electromagnetic waves do not require a medium to travel in unlike sound waves which needs solid, liquid or gas mediums.
Bluish-white, lustrous metal. Brittle at ambient temperatures, however it is malleable at 100 to 150 degrees (C) and is a 'okay' conductor of electricity. The density is 7.140 g/mL. This means the mineral will sink in water and is reasonably heavy. (These are physical, if you need them)
(These will be chemical, what you asked for.) It is based upon sulfide ores. It is roasted in industrial plants to form zinc oxide, ZnO. This may be reduced with carbon to form zinc material. Zinc burns in air at high red heat with evolution of white clouds of the zinc oxide.
Answer:
The magnitude of the centripetal force to make the turn is 3,840 N.
Explanation:
Given;
radius of the cured road, r = 400 m
speed of the car, v = 32 m/s
mass of the car, m = 1500 kg
The magnitude of the centripetal force to make the turn is given as;
where;
Fc is the centripetal force
Therefore, the magnitude of the centripetal force to make the turn is 3,840 N.
