Answer:
Proper weighting
Explanation:
Proper weighing involves the condition of a scuba diver that is fully geared having a near empty tank and the BCD emptied with a held breadth is expected to float at eye level
The fundamental of adequate or good buoyancy of a scuba diver is to ensure proper weighting when diving, With proper weighting, there is more control for the diver when a safety stop is required. There is less need to carry excess weight that increases drag and gas consumption.
260 volt is the answer i think
Answer:
Position = behind the mirror
Nature = Virtual and Erect
Size = : Diminished
Explanation:
Sign convention-Distance measured to the left of pole is negative and to the right of pole is positive.
Object distance = u = -20 cm
Focal length = f = Radius of curvature/2 = 30/2 = 15 cm
We have to use mirror formula to find image distance.
Since the image distance is positive, it is formed behind the mirror or a virtual image is formed.
Magnification =
Height of the object = 5 cm
Height of the image =
Since the height of the image is positive and less than the size of object,it is erect and diminished.
Answer:
- 0.328J
Explanation:
POTENTIAL ENERGY = mgh
= 0.00274 × 9.81×12.2 here 2.74g = 0.00274kg
= 0.32792868 J
= 0.328J
AS IT IS BELOW THE SURFACE HENCE MUST BE NEGATIVE
hence potential energy = - 0.328J
