The bees wing are moving very fast the best wings are much smaller than it body ?
marishachu [46]

Explanation:

It is true that the wings of the bee move very fast. The wings are smaller than their body and it is believed to be difficult for the wings to lift the whole body of the bee.

Sometimes, bees carry nectar and pollen with itself which again increases their weight. It has been found that the wings do not move up and down rather moves to and from. Since air is denser, it tries to push the air downwards and lift itself upwards.

The half — life of nickel is 96 years. How much of a 30-gram sample is left after 270 years?
-Dominant- [34]

The amount of the 30 gram-sample that will remain after 270 years is 6.61 grams

<h3>How to determine the number of half-lives </h3>

We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:

  • Half-life (t½) = 96 years
  • Time (t) = 270 years
  • Number of half-lives (n) =?

n = t / t½

n = 270 / 99

n = 2.8125

<h3>How to determine the amount remaining </h3>
  • Original amount (N₀) = 30 grams
  • Number of half-lives (n) = 2.8125
  • Amount remaining (N) =?

The amount remaing can be obtained as follow:

N = N₀ / 2^n

N = 30 / 2^2.8125

N = 6.61 grams
