Answer:
Biodiversity decline continues due to a rapidly expanding human population. Habitat is damaged in order to meet growing needs for agriculture, urban development, water and materials. Fish, wildlife and plants are overharvested, despite mounting evidence that many harvesting practices are unsustainable.
<span>The length of the year is equivalent to the time it takes for the earth to go around the sun one time.</span>
S = 16t² where t = time in seconds.
Let S = 1190ft then solve for t:
16t² = 1190
t² = 74.4
t = 8.62s
Answer:
The diameter is 0.378 ft.
Explanation:
Given that,
Mass of shot = 12 lb
Density of fresh water = 62.4 lb/ft
Specific gravity = 6.8
We need to calculate the volume of shot
The density of shot is
Using formula of density
Put the value into the formula
We need to calculate the radius
Using formula of specific gravity
Put the value into the formula
The diameter will be
Hence, The diameter is 0.378 ft.
On the whole, the metals burn in oxygen to form a simple metal oxide. Beryllium is reluctant to burn unless it is in the form of dust or powder. Beryllium has a very strong (but very thin) layer of beryllium oxide on its surface, and this prevents any new oxygen getting at the underlying beryllium to react with it.
