Answer 1

Explanation:

4.iodine would be used to test for sugar

6. mass is constant everywhere while weight differs from place to place due to gravity changes

Answer 2
4. Test for starch - turns blue black if present
5. Test for reducing sugars - mix solution with Benedict’s reagent and put in water bath for ~30 min, greater colour change means more sugars present

7. Mateo and Jackie were on a playground rolling some different-sized balls to get them to crash. They used a tennis ball (the same mass) in both crashes. They tried two soccer balls—a pink one (more mass) for Crash 1 and a blue one (less mass) for Crash 2. Mateo and Jackie want to know what happened to the tennis ball. Use information from the diagram to answer. In which crash did the tennis ball experience a stronger force? How do you know?

Answers

Answer:

The answer is Crash 1, because the pink soccer ball had a greater amount of mass so it would expirence a stronger force.

Hope this helps! :)

Answer:

crash 1

Explanation:

Because crash one has a higher mass which will have a bigger force or hit because it weighs more

for example when i shoot an arrow harder then i shoot an arrow slower which will make it farther the arrow because i gave it more energy with more force
