Timothy always liked playing catch with his dad. Whenever he had the chance to pick up a small object, he simultaneously threw a random object at his dad to catch him of guard. His objective was to have his dad drop the item. One day, Timothy threw two objects at is dad. One object was a tennis ball and the other was a golf ball. His dad ended up dropping both of the objects on the floor but was able to catch them after the drop because they both bounced back into his father’s hands. He wondered how this was possible???? This led to Timothy asking a science question that he would like to test by doing an experiment. What science question do you think Timothy asked to jumpstart an investigation?

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?
Answers
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

A student uses red litmus paper to test the pH value of different solutions. Which would result in a color change of the litmus paper?
soap
vinegar
lemon juice
antifreeze
Answers
The litmus paper shows red colour for acidic substances and blue colour for basic substances. Thus a red litmus paper will turn blue if it is dipped in an alkaline solution. Soap is alkaline and given blue color to litmus.
What is pH?pH of a substance is its measure of concentration of H+ ions in it. It is mathematically negative logarithm of H+ ion concentration. Thus, pH measures how much acidic or basic the solution is.
A pH of of 7 is neutral having no acidity or basicity. A pH less than 7 is acidic and pH greater than 7 is basic in nature. Vinegar is acetic acid and it shows less pH . Lemon juice also acidic since it contain citric acid whereas, soap is basic.
A litmus paper is used to identify whether a substance is acidic or basic. It shows red color for acidic solutions and blue for basic solutions. If the red litmus paper is dipped in acidic one, it shows no colour change if it is dipped in basic solution then it turns to blue.
Soap is highly alkaline and it changes red litmus paper to blue.

Which statement about exothermic reactions is true?
Responses
The reactants create energy to form products.
Energy from an outside source is continuously being added.
More heat is given off than is put into the reaction.
The reaction container always feels cold.
Answers
Answer:An exothermic reaction may be defined as a type of reaction in which energy is significantly liberated in the form of heat or light. In such types of reactions, energy is generally transferred into the surroundings rather than utilized from the surroundings.
The option "energy from an outside source is continuously being added" represents an endothermic reaction in which heat or light energy is externally been provided. The option "more heat is given off than is put into the reaction" is not absolutely true because exothermic reactions liberate energy but it does not matter if it is higher or lower than that of being put into the reaction.
Therefore, the reactants have more heat energy than the products is a statement that is true about exothermic reactions. Thus, the correct option for this question is C.
Explanation:
you welcome
Energy from outside sources is continuously being added, since its an exothermic reaction it always focusses on releasing large amount of energy upon activation and combustion.
It cuts off on giving energy back to its surrounding unlike endothermic reaction where the generated energy is given back to the environment to restore its energy levels.
Therefore, it makes it clear that exothermic reaction is a type of reaction that uses combustion to gather the energy lying around in the surrounding to generate large amount of energy and heat and keeps on producing heat until and unless there is energy in surrounding.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Max and Jimmy want to jump on a trampoline. Max begins jumping in a steady pattern, making small waves in the trampoline. Jimmy starts jumping on the trampoline too. Suddenly, Max goes twice as high even though he did not put any extra effort into jumping.
What type of wave interaction is this? Explain how it occurred.
Answers
Because there is one wave interfering with the other. They are both separate waves with completely different patterns, and they are running into each other.
Hope this helps! :)
Answer: The wave interaction described in the scenario is known as constructive interference.
Explanation:
Constructive interference occurs when two waves meet and combine in such a way that their amplitudes add up, resulting in a larger wave. In this case, Max's steady pattern of jumping creates small waves on the trampoline, with a certain amplitude.
When Jimmy starts jumping on the trampoline, his waves combine with Max's waves. If the peaks and troughs of both waves align perfectly, they will add up, resulting in a wave with a larger amplitude. This alignment of peaks and troughs leads to constructive interference, causing Max to go twice as high without any additional effort.
The reason behind this phenomenon lies in the nature of waves. When waves meet, their amplitudes can either add up or cancel out, depending on their relative positions. In the case of constructive interference, the peaks of one wave align with the peaks of the other wave, and the troughs align with the troughs, resulting in an increased amplitude. Conversely, in destructive interference, the peaks align with the troughs, leading to a cancellation or reduction in amplitude.
So, in the scenario, Jimmy's waves align with Max's waves in such a way that their amplitudes combine constructively, resulting in Max going twice as high on the trampoline without exerting any extra effort.
