The final velocity is 0 and the acceleration is gravity. Vf=Vi+at because gravity opposes the motion it will be -g
0=250-gt
gt=250 ....g=10
t=25sec
Answer:
History and physics are intertwined through all the revolutionary thinkers, scientists, and people who studied these ideas. For example, many historical thinkers such as Isaac Newton and Galileo Galilei not only had revolutionary ideas, but they also changed life forever as the people knew it. It shocked the people and taught them new things, and upset the church.
Explanation:
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.
The answer would be 40 cause 10*4=40
Formula for Velocity = DISTANCE traveled/TIME to travel distance + direction
For this one, we can use mph(miles per hour) as unit.
v = 1,000 miles / 336 hours (2 weeks = 24 hours x 14 days = 336 hrs)
= 2.98 mph North
or we can use kph (kilometers per hour)
v = 1609.34 km / 336 hours (1 mile = 1.60934 km)
= 4.79 kph North
