B. The thickness of ice increased recently.
Is gravity positive or negative?
If up is positive then, since gravity points down, gravity would be in the negative direction. For example, if I'm just standing here on the ground is gravity working in a positive or negative direction. Gravity is an attractive force. The earth applies a downwards force on you, and you apply an equal and upwards force on the earth.
What does it mean if my specific gravity is high?
The results do signal other health conditions that may harm your health. The normal specific gravity ranges from person to person. Your urine-specific gravity is generally considered normal in the ranges of 1.005 to 1.030. If you drink a lot of water, 1.001 may be normal. If you avoid drinking fluids, levels higher than 1.030 may be normal.
