Answer:

Explanation:
power through string can be determined as shown in figure

Where
P = 57.3 W
V = 13.87 m/s
H = 567 g/m
we know that


therefore 


Answer:
2.5 kg/m³
Explanation:
Absolute pressure = gauge pressure + atmospheric pressure
P = Pg + Pa
The gauge pressure caused by the weight of a fluid is called the static pressure. It is equal to the density of the fluid × acceleration due to gravity × depth of the fluid,
Pg = ρgh
Therefore:
P = ρgh + Pa
300 Pa = ρ (10 m/s²) (8.00 m) + 100 Pa
ρ = 2.5 kg/m³
Ah yes the language of enchantment book
The correct answer is (c.) hot spring. Naturally hot water containing many minerals and found on the surface of the Earth is called a hot spring. These springs' occurrence are caused by the emergence of geothermally heated groundwater. These springs are perfect for hot bath, though others are way too that might cause injury or death.
