Answer: They are the same.
Expatiation:
Buoyant force: An upward thrust exerted by any fluid on an object placed in it.
According to Archimedes' principle which states that 'upward thrust exerted by the fluid on an object immersed in a fluid whether partially or fully is equal to the weight of the fluid displaced by the immersed body'.This force acts in the upward direction at the center of mass of the displaced fluid.
Hence, it is correct to say that weight of the water displaced compare to the buoyant force are the same.
Answer:
the answer is descriptive
Explanation:
descriotive never ever have hypothisis
Answer : As the temperature of a medium increases, the speed of the sound wave increases because the particles bump into each other more often.
Explanation :
The dependency of the speed of the sound wave and the temperature of the medium is :
Where
= ratio of specific heat
R is gas constant
T is the temperature
The speed of the wave is directly proportional to the temperature. As the temperature of a medium increase, the speed of the sound increase. The particles start vibrating faster. Hence, they bump into each other.
Hence, the correct option is (A).
Answer:
The ring of fire
Explanation:
The ring of fire is where they meet or at the fault lines
Explanation:
The question involves converting from one unit (Kilometres) to another unit (Astronomical unit)
The relationship between both units is given as;
1 Km = 6.68459e-9 Au
Kulper belt
6.5 billion km = 6.5e9 Km
1 Km = 6.68459e-9 Au
6.5e9 Km = x
Solving for x;
x = 43.45 Au
Alpha Centauri
44 trillion km = 4.4e13
1 Km = 6.68459e-9 Au
4.4e13 km = x
Solving for x;
x = 294121.83 Au
