Answer:
C.
Explanation:
Ultraviolet light shining on the minerals will cause them to give off visible light.
The object is in a state of equilibrium.
Answer:
Explanation:
Period of oscillation ∝ √ m
So period of oscillation is proportional to square root of mass
So when mass increases , period too will be increased . But the total energy will remain the same as per conservation of energy.
Hence option ( D) is the correct answer.
Answer:
The volume of the bubble near the surface will be 9.47 m³
Explanation:
Given that,
Depth = 52.0 m
Volume = 1.50 m³
Temperature at bottom = 5.5°C
Temperature at the top = 18.5°C
We need to calculate the pressure at the depth 52.0 m
The pressure is
Where, = Pressure at the surface
= Pressure at the depth
Put the value into the formula
We need to calculate the volume of the bubble just before it reaches the surface
Using equation of ideal gas
Now, The equation of at bottom and top
Put the value into the formula
Hence, The volume of the bubble near the surface will be 9.47 m³
