The ozone layer protects us from the harmful emission of rays directly to the environment. Absent this added layer of protection we humans will be susceptible to various forms of cancer due to over radiation and eye problems such as cataracts. It is estimated that 10% of the world's population will face the consequences of ozone depletion this year and these numbers were continue to rise as time progresses.
Answer:
It was an difficult place to live because the animals had to survive the waves and different type of water levels and temperture changes.
Explanation:
The free body diagram consists of:
1) Weight force, which is a vertical arrow downward
2) A Normal force that is perpendicular to the ramp.
The Normal force can be decomposed in a vertical component and an horizontal component.
The vertical component, Ny, must equal the weight force, due to equilibrium (rest) condiition =>
Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N
By geometry the vertical component of the Normal force, Ny is such that
cos (angle) = N / Ny => N = Ny * cos(angle)
=> N = 53.9N * cos(angle)
Now use that equation for each option:
a) 0 ° => N = 53.9N * cos(0) = 53.9N
b) 12° => N = 53.9 * cos(12) = 52.7N
c) 25° => N = 53.9 * cos(25) = 48.9N
d) 45° => N = 53.9 * cos(45) = 38.1N
The factors that contributed to the environmental problems which exist in Europe was that B. Much of Europe is densely populated.
How does the Earth create a magnetic field?
The Earth’s magnetic field is created by the rotation of the Earth and Earth's core. It shields the Earth against harmful particles in space. The field is unstable and has changed often in the history of the Earth.
