Answer:
E. 1.18x10^4nm/ms^2
Explanation:
The aceleration of the train is given in m/s². We need to conver, first, the meters to nm and then, the seconds to ms as follows:
11.8m/s² * (1x10⁹nm / 1m) = 1.18x10¹⁰nm / s²
Now, as 1s is equal to 1000ms:
1.18x10¹⁰nm / s² * ((1s)² / (1000ms)²)) =
1.18x10⁴nm / ms²
Thus, right option is:
A train's acceleration of 11.8 m/s^2 converts to 11.8*10^7 nm/ms^2 while converting from meters to nanometers and from seconds squared to milliseconds squared.
To convert a value from meters (m) to nanometers (nm), we must multiply by the conversion factor of 1×10^9nm/1m. A nanometer is one billionth (10^-9) of a meter. In this case, the train is accelerating at 11.8 m/s2. Therefore, the acceleration in terms of nanometers per second squared (nm/s2) is 11.8 * 109 nm/s2. To convert this value to nanometer per millisecond squared (nm/ms2), we know there are 1000 milliseconds (ms) in a second (s). Hence, we divided by 1000 squared, resulting in 11.8 * 109 nm/s2 divided by 10002 to get the answer in (nm/ms2). This gives us 11.8*107 nm/ms2, so the correct answer is C.

A change on the molecular level.
A change in appearance.
A change in taste.
A change in form.
The phrase that most accurately describes a chemical change is; "A change on the molecular level."
The major difference between a physical change and a chemical change is that a chemical change involves a change in the composition of a substance.
This implies that the atoms in a substance are rearranged during a chemical change.
This rearrangement of atoms corresponds to change on a molecular level.
