It is important that engineers build a structure that is safe. What do they look for when testing their designs?

Failure points
Fair tests
Prototypes
Variables

Answers

Variables
or failure points

Answer:

Failure Points

Explanation:

Engineers want to test the areas that may possibly fail when they are building designs so when they go to actually build it they know it will not fail.

Can someone please explain the cause and effect between the rearrangement of atoms and molecules in a chemical reaction and the different properties that the products have from the reactants.

Answers

Answer:

In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Explanation:

Compare and contrast the alkaline battery and a Zinc carbon battery. put in some other facts about them too. write somewhere around 2 paragraphs.



I'll mark brainlyest to whoever has the best answer and give them 50 points for helping me.

Answers

The alkaline batteries, have a higher energy density and the time a battery can remain in storage without losing any of its capacity. Also, there is a specially designed coating inside the batteries that reduces contact resistance for greater reliability. Lastly, the alkaline cells have an extra power formula to maintain power for a longer period of time in high drain devices. Alkaline batteries provide more energy than zinc carbon batteries.

The Zinc carbon batteries, are a reliable source of power for appliances that consume little energy. Some examples are: remote controls for televisions, clocks, and smoke detectors. A reason that you should use the Zinc carbon batteries is for, the low energy consumption. This will lead to being able to use the appliances for a longer time for the same money.

The difference between the batteries is the capacity. Because of composition, an alkaline battery, delivers more energy than a zinc carbon battery.
The only downside is that, both batteries need to be used in different appliances.

The motion of ball B will decrease.
The motion of ball B will stay the same.
The motion of ball B will become the same as ball A.

Answers

Answer:

The motion of ball B will increase

Explanation:

Because if you hit ball A with less force than ball B then that means that ball B will go faster because you had hit ball A will less force witch will not be as faster as ball B.
