Answer: 65000 seconds
Explanation:
Given that,
Current (I) = 2 mA
(Since 1 mA = 1 x 10^-3A
2 mA = 2 x 10^-3A)
Charge (Q) = 130 C
Time taken for a fully charged phone to die (T) = ?
Recall that the charge is the product of current and time taken.
i.e Q = I x T
130C = 2 x 10^-3A x T
T = 130C / (2 x 10^-3A)
T = 65000 seconds (time will be in seconds because seconds is the unit of time)
Thus, it will take a fully charged phone 65000 seconds to die
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.
