Answer:
Color, Streak, luster, cleavage and fracture, hardness, crystal shape, and density.
Explanation:
Transforming crude oil into petrochemicals release toxins into the atmosphere that are dangerous for humans and ecosystem health
Electromagnetic waves are the waves that can travel without a material medium.
Explanation:
Given that,
Initial speed of a car, u = 60 km/h = 16.67 m/s
Acceleration, a = 2m/s²
Final speed, v = 120 km/h = 33.33 m/s
We need to find the distance traveled and the time taken to make the distance.
acceleration = rate of change of velocity

let the distance be d.

Hence, the distance traveled and the time taken to make the distance is 208.25 m and 8.33 seconds respectively.
