I believe your answer would be D- Physical properties of matter effect the chemical properties of matter.
Hope this helps. Tell me if I'm right.
IS any one going to answer this I need the answer also

Answer:
Explanation:
The angular speed is defined as the angle traveled in one revolution over the time taken to travel it, that is, the period. Therefore, it is given by:
The angular frequency of the simple harmonic motion of the mass-spring system is defined as follows:
Here, k is the spring's constant and m is the mass of the body attached to the spring. Solving for k:
Answer:
60°
Explanation:
It will be equilateral triangle, you can prove with the cosine theorem.
1)P^2=P^2+P^2 - 2×P×P× cos A
2) cos A= P^2 / 2× P^2 = 1/2
cos A = 1/2
A = 60°
If you wrote this question right,it will be solved like this :)
Speed = distance / time
speed = 100 / 11
speed = 9.09m/s
to get rid of meters and get miles you want to multiply by 1 mile then divide by 1609 meters. to get hours, you times the amount of seconds in an hour (3600) and divide by 1 hour
9.09m/s × 1mile / 1609m × 3600s / 1 hour = 20.3 miles / hour
