Two explanations might include two sets of colorless solutions that might yield a gas. What comes to mind is the production of carbon dioxide which could come from a soluble carbonate, such as sodium carbonate solution, and an acid, such as vinegar or hydrochloric acid.  A second possibility is a gas such as ammonia.  This could be produced by the reaction of a soluble ammonium compound, such as ammonium chloride, and a base such as sodium hydroxide.

Anika asks Eva to roll a basketball and then a bowling ball to her. Which requires more force to roll, and why?
Paul [167]

It's easy to roll the the basket ball than bowling ball

It is because bowling ball is solid spherical ball which will have less moment of inertia

its moment of inertia is given as

I = \frac{2}{5}mR^2

While for the hollow ball like basketball we know that moment of inertia is given as

I' = \frac{2}{3}mR^2

so here we can see for the same mass if we take basketball then its moment of inertia is more so it is easy to roll basket ball then to roll bowling ball.

So it is easy to roll basket ball then rolling ball

A triangle has two sides of length 10 cm and 14 cm. what can you say about the length of the third side?
Anton [14]

A side of any triangle is less than the sum of the other two sides so the third side must be less than 24cm.

<h3>What is a triangle?</h3>

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

In any triangle, the sum of two sides is always greater than the third side.

If the third side is equal to the sum of two sides then it will be a straight line rather than a triangle.

It means 10 + 14 > third side

24 cm > third side

Hence "A side of any triangle is less than the sum of the other two sides so the third side must be less than 24cm".

Which is developed during the process of technological design?
lbvjy [14]

Answer: SOLUTION

Explanation: A technological design is often adopted when there is a need to solve or find solution to a certain or identified problem. The technological design process is often required in other to develop technologically driven products which is capable of providing solution to a perceived problem. The steps involved includes;

Identifying the problem at hand, carrying out further and thorough research on them, proferring possible solutions out of which the best possible approach is selected. Then the solution is modeled, the model is tested and refinements are made depending on outcome of the test. Testing will have to be repeated upon refinement of the model before the final outcut is communicated.
