Answer:
It spreads out into multiple shadow regions
Explanation:
- when the waves meet the barrier than light is diffracted as When this occurs, the wave bends around the corners of the barrier or passes through the opening of the wedge, which acts as a barrier, forming several patterns with the hole shape of the wedge.
- and The main condition for this phenomenon to occur is that the magnitude of the barrier must be equal to the magnitude of the wavelength.
- when sunlight as an electromagnetic waves is passes by key hole of gate, then this light will break and form many keyhole-shaped shadow fields.
This question involves the concepts of density, volume, and mass.
The approximate diameter of a magnesium atom is "3.55 x 10⁻¹⁰ m".
<h3>STEP 1 (FINDING MASS OF INDIVIDUAL ATOM)</h3>
It is given that:
Mass of one mole = 24 grams
Mass of 6 x 10²³ atoms = 24 grams
Mass of 1 atom = = 4 x 10⁻²³ grams
<h3>STEP 2 (FINDING VOLUME OF A SINGLE ATOM)</h3>
where,
- = density = 1.7 grams/cm³
- m = mass of single atom = 4 x 10⁻²³ grams
- V = volume of single atom = ?
Therefore,
V = 2.35 x 10⁻²³ cm³
<h3>STEP 3 (FINDING DIAMETER OF ATOM)</h3>
The atom is in a spherical shape. Hence, its Volume can be given as follows:
d = 0.355 x 10⁻⁷ cm = 3.55 x 10⁻¹⁰ m

Acceleration = (change in speed) / (time for the change).
Acceleration = (14 m/s - 0 m/s) / (3.5 s) = <u>4 m/s²</u>
