Answer:

 Time taken to travel remaining 228 miles = 2.4 hours.

Explanation:

Total distance = 876 miles.

Distance traveled after speed reduction = 228 miles

So, distance traveled before = 876 - 228 =648 miles.

Time taken for this = 6 hours.

Speed before speed reduction = 648/6 = 108 mph.

Speed after speed reduction = 108 - 13 = 95 mph

Time taken to travel remaining 228 miles = 228/95 = 2.4 hours.

Illusion [34]

Answer:

Testing

Explanation:

Ancient Greek philosophers lived with the ideology to simply contemplate life. This means that their whole life revolved around thinking and questioning everything. This would include creative thinking, because they would sometimes come up with theories which require creativeness. They would often debate with their friends as to why their theory should be accepted or what their opinions were on the matter. More often than not, they argued a lot, and many philosophers went against some powerful people in the community and some were even sentenced to death.

The main process they didn't/couldn't do was the testing. They could never test certain theories because they did not have the means to.

An experiment is performed aboard the International Space Station to verify that linear momentum is conserved during collisions
Anni [7]

Answer:

v=15.9554\ m.s^{-1}

Explanation:

Given:

  • mass of the honey drop 1, m_1=35.5\times 10^{-3}\ kg
  • velocity of the honey drop 1, v_1=13.1\ m.s^{-1}
  • mass of the honey drop 2, m_1=52.3\times 10^{-3}\ kg
  • velocity of the honey drop 2, v_2=14.5\ m.s^{-1}
  • mass of the honey drop 3, m_1=75.7\times 10^{-3}\ kg
  • velocity of the honey drop 3, v_3=18.3\ m.s^{-1}

<em>In ISS there is zero gravity an the collision is completely inelastic.</em>

<u>So, applying the law of conservation of momentum:</u>

m_1.v_1+m_2.v_2+m_3.v_3=(m_1+m_2+m_3).v

35.5\times 10^{-3}\times 13.1+52.3\times 10^{-3}\times 14.5+75.7\times 10^{-3}\times 18.3=(35.5+52.3+75.7)\times 10^{-3}\times v

v=15.9554\ m.s^{-1}

What is the Sl unit for speed
Akimi4 [234]

Answer: meter per second

Explanation: meter per second

Speed has the dimensions of distance divided by time. The SI unit of speed is the meter per second, but the most common unit of speed in everyday usage is the kilometer per hour or, in the US and the UK, miles per hour. For air and marine travel the knot is commonly used.
