The motion of an airplane when the pilot changes the throttle setting of the engine is described by the first law. The motion of a ball falling down through the atmosphere, or a model rocket being launched up into the atmosphere are both examples of Newton's first law.
Answer:
The gain,loss, or sharing of electrons occurs in every chemical bond.
Explanation:
Should electrons be lost by one particle, and gained by another particle, the now charged particles can be chemically bound by an ionic bond.
Should a pair of electrons form a region of high electron density between two positively charged atomic nuclei, a bond can occur in that mutual attraction of the positively charged nuclei towards the region of high electron density operates. This is a long-winded description of a covalent bond.
The apple is lifted by 1.1 m
<u>Explanation</u>:
- Given that, mgh = 2 J and mass of apple = 180g
- Step 1: convert grams to kg as work is given in SI units.
180 g = 0.18 kg
- Step 2: substitute in the formula for work done.
0.18 * 10 * h = 2
- Step 3: calculate the value of h from this formula.
h = 2/1.8
h = 1.11 m
