The answer would be a.
a chemical change is a change to the chemical makeup of a substance so if the bonds are unchanged it would be a characteristic of a physical change
Answer:
L = 3.51
Explanation:
Pendulum equation is T = 2pi![\sqrt{L/9.81}](https://tex.z-dn.net/?f=%5Csqrt%7BL%2F9.81%7D)
T = 1.5 and we are solving for L
1.5=2![\pi \sqrt{L/9.81}](https://tex.z-dn.net/?f=%5Cpi%20%5Csqrt%7BL%2F9.81%7D)
square both sides to get 2.25 = 2![\pi ( L/9.81)](https://tex.z-dn.net/?f=%5Cpi%20%28%20L%2F9.81%29)
multiply both sides by 9.81 then divide by 2 and 3.14 as a substitue for pi. The answer should be about 3.51 in length
L = 3.51

<span>The car would have traveled exactly one-half of the circumference of the track, since it would have gone from one extreme point to its opposite extreme point. This would be equal to (3.5 / 2), or 1.75 km. The northernmost point would be 1.75km away from the southernmost point.</span>
Answer:
In physics, if there is biggest mass then the slow down time is more and this effect is basically known as gravitation time dilation. This type of effect can easily be calculated from the different type of metric in the environment.
When some outsider observe then, this effect time seemed to be slowed down. It basically measure the overall amount of the time which elapse at observer distance. Therefore, this is the main concept of the mass slow down time.
Answer: D. When both objects reach the same temperature.
Explanation: When will heat flow between the objects stop? Heat will always flow from the warmer object to the colder object. The heat transfer will stop when the two objects are at the same temperature and reach thermal equilibrium.
