<span>You push a cart and then you take some items out of your cart. Your work will decrease because you have less to push.
The cart is lighter, so there is less friction, which means that it will be easier to move it.

The answer is B. Sunlight (white light) refracts when it passes through droplets of water in the atmosphere
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.
K.E = 1/2 mv²
100 = 1/2 (2 )(v)²
100 = both 2 cancel (v)²
Taking Square root on b/s
√100 = √v²
10 = v
