Answer:
the crown was not made of pure gold
Explanation:
Mass of gold = weight in air/ g = 7.84N/10ms-2= 0.784 Kg or 0.8Kg
From Archimedes principle:
Upthrust= weight in air- weight in a fluid
Upthrust= volume × density × g
Note density of water = 1000kgm-3
7.84-6.84= V × 1000kgm-3×10ms-2
V= 1/10000= 1×10-4 m^3
Density = mass/ volume= 0.8/1×10-4
= 8×10^3 Kgm-3
But we know the density of gold to be 19.3 ×10^3 kgm-3
Hence the crown was not made of pure gold
Answer: The resultant displacement vector is 5.6km
Answer:
Psychology is theoretically diverse.
Explanation:
The theme, 'Psychology is theoretically diverse' means that the psychology has many various views and points. This is because when people make many observations they can go several and many different ways with these observations. This is why Psychology has many perspectives. The differing perspectives provide complete understanding of the human behavior more effectively.
Hence, different perspectives of the three professionals mentioned illustrate this theme.
Answer:
C. simple
The term that refers to the fact that an epithelial tissue has only one layer of cells is simple epithelial.
Explanation:
Epithelial tissues are thin tissues that cover all the exposed surfaces of our body.
Based on the number of cell layers, the simplest classification of epithelial tissue is:
a. Simple Epithelial Tissue
When the epithelial tissue consists of a single layer of cells, it is called simple epithelial tissue.
b. Stratified Epithelial Tissue
When there are two or more layers of cells in epithelial tissue, it is called stratified epithelial tissue.
Cuboidal epithelial is also a type of simple epithelial tissue.
Pseudostratified is another type of epithelial tissue which falls in neither simple nor stratified category. They consists of a single layer but the positioning suggests it is stratified.
There are 3 types of epithelial tissues based on their shape:
a. Squamos epithelial tissue
b. Cuboidal epithelial tissue
c. Columnar epithelial tissue
