Answer:
The average speed of the bus, v = 1.55 m/s
Explanation:
Given that,
Number of blocks traveled by bus towards east = 6
Number of blocks traveled by bus towards north = 8
Length of each block = 100 m
Distance traveled by bus towards east 6 x 100 = 600 m
Distance traveled by bus towards north 8 x 100 = 800 m
The total distance traveled, d = 600 + 800 = 1400
Time taken by the bus to travel is, t = 15 minutes
The velocity is given by the formula
v = d/t m
Substituting the values in the above equation
v = 1400 m /(15 x 60) s
= 1.55 m/s
Hence, the average speed of the bus, v = 1.55 m/s
Options:
- The impact of Earth’s gravity on the decay rate of deuterium is the same as the impact of microgravity.
- Most of the water that forms the oceans of Earth arrived by way of impacts with Kuiper Belt comets.
- Most comets formed from deuterium-based water that was stripped away from early Earth by solar radiation.
Answer:
<u>Most of the water that forms the oceans of Earth arrived by way of impacts with Kuiper Belt comets.</u>
Explanation:
Note, a comet is a celestial body made of ice which releases gases when it orbits close to the Sun. Deuterium is a type of element which can be found in comets and in our oceans on earth. Deuterium is considered an isotope of hydrogen.
Hence, because of the similarities between the Deuterium and Hydrogen, some scientists promote the theory that most of the water that forms on oceans of the earth<em> likely</em> arrived by the impact with Kuiper Belt comets.
