The amount of solar heat that hits the ground and DOESN'T go back into space increases, so that the Earth gets warmer, weather patterns change, growing seasons change, climates change, polar icecaps shrink, and animal habitats change. There's no "might" about it. That's exactly what's happening right now.
Answer:
Strain has no units due to simply being the ratio between the extension and original length of a material, so Young's Modulus is measured by the same units as stress... like newtons per square meter (Nm-2) or Pascals (Pa).
Answer:
Velocity=0.2m/s
Explanation:
Velocity=displacement / time
Velocity=7.6m/38s
Velocity=0.2m/s
Answer:
9m
Explanation:
Given parameters:
Volume of the water = 5liters;
Since density = 1g/cm³
1L = 1000cm³
5L = 5000cm³
So;
mass = density x volume = 1 x 5000 = 5000g ; 5kg
Work done = 450J
Acceleration due to gravity = 10m/s²
Unknown:
Depth of the well = ?
Solution:
To solve this problem;
Work done = mass x gravity x depth
450 = 5 x 10 x depth
depth = 9m
