Complete Question:
The momentum of an object is determined to be 7.2 × 10-3 kg⋅m/s. Express this quantity as provided or use any equivalent unit. (Note: 1 kg = 1000 g).
Answer:
7.2 gm/s.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Given the following data;
Momentum = 7.2 * 10^-3 kgm/s
1 kg = 1000 g
Substituting the unit in kilograms with grams, we have;
Momentum = 7.2 * 10^-3 * 1000 gm/s
<em>Momentum = 7.2 gm/s. </em>
The statement that is true is that positively charged objects attract negatively charged objects. This is due to a law that states 'like forces attract while unlike forces repel. This same concept applies to magnetism. If you put two similar poles together, for example; if you place two south poles together. You feel a separating force between the two poles. But if you place two opposite poles together they attract each other. Hope i helped. <span />
Chemical stimuli are molecules that cause a response at a cellular level primarily through cellular receptors. This happens all the time in nature - cells communicate with one another through chemical messaging. An example is an aroma molecule, such as the scent from a flower. This particular molecule is detected by the olfactory cells (those associated with the sense of smell) in your nose, producing a chemical reaction that ultimately leads to you consciously experiencing the smell.

<span>77.2 k is -195.95 C
To convert from Kelvin to Celsius, you simply subtract 273.15 from the temperature. So the expression becomes
c = 77.2 - 273.15 = -195.95</span>
