Answer:

Cells need to divide to reproduce.

Explanation:

They go through numerous stages, such as mitosis to further replicate themselves. They can't get things done alone, so they have to work in numbers.

At a certain temperature the speeds of six gaseous molecules in a container are 2.0 m/s, 2.2 m/s, 2.6 m/s, 2.7 m/s, 3.3 m/s, and
iren [92.7K]

Answer:

root-mean-sqaure = 2.77 m/s

average = 2.72 m/s

The root-mean-square is always the largest because it takes account of the variance of the spread of the data. The increase is related to the fact that the data varies to sample.

Explanation:

The rootmean-square (R) is the square root of the squares of the valeus divided by the number of the datas.

R = \sqrt{\frac{x1^2 + x2^2 +...+xn^2}{n} }

R = \sqrt{\frac{(2.0)^2 + (2.2)^2 + (2.6)^2 + (2.7)^2 ^(3.3)^2 + (3.5)^2}{6} }

R = √(46.03)/6

R = 2.77 m/s

The average speed is the sum of the speeds divided by the number of datas:

A = \frac{2.0 + 2.2 + 2.6 + 2.7 + 3.3 + 3.5}{6}

A = 16.3/6

A = 2.72 m/s

Neptune's Triton is being pulled closer and closer to the planet as it orbits. What will likely be a result of this gravitationa
Ksenya-84 [330]

Answer:

the planet's gravity will cause Triton to fly into Neptune

Explanation:

Gravitational force is a force of attraction between two bodies with considerable masses.

One of the mass tends to pull the other to it's center.

As the force of gravity between two bodies grow, the more massive body will be drawn to the other one.

  • The effect is that one body will eventually collide with the other.
  • Since the planet pulls very hard on its moon
  • On the long run, we can expect Triton to fly into Neptune in the foreseeable future.

How does convection occur in the troposhere ​
adell [148]

Answer:The surface heated air expands as it warms, becomes less dense than surrounding cooler air and rises as buoyant and turbulent bubbles. This is convection and is the main process by which the troposphere mixes and heats. Although convection stirs and mixes the troposphere, the higher it is the colder it becomes.

Explanation: Read this and you'll get your answer~! I hope i helped you~! Have an GREAT day too~! <\3
