Answer:
People at the equator do not experience the large changes in sun angle that people at northern and southern latitudes experience,
Since the earth is tilted about 23 deg from its ecliptic, a person
at 40 deg north would experience sun angles from 17deg at the summer solstice to 63 deg at the winter solstice while someone at the equator would only experience changes from -23 deg to + 23 deg.
Also, the coriolis effects of wind velocity are much less noticeable at the equator.
Hurricanes normally do not occur at the equator
Answer: SF6
Explanation: Hexa is a prefix means 6. Sulfur Hexafluoride is expressed in SF6
Answer:
Mass of water,
Explanation:
Given that,
Surface area of the reservoir, A = 30 km² = 3 × 10⁷ m²
Average depth, d = 49 m
The volume of the reservoir is V such that,
We have to find the mass of water is held behind the dam. It can be calculated using the expression for density. We know that density of water, d = 1000 kg/m³
Density,
Hence, this is the required solution.
