A ball is dropped from a cliff that is 135 m high.
Anna [14]

Answer:

113 feet

Step-by-step explanation:

I will assume you meant h = -4.9t^2 + 135; "t2" is incorrect.

To answer this question, to find the height of the ball after 2.1 seconds, substitute 2.1 for t in the above equation:

h(2.1) = -4.9(2.1)^2 + 135.  This becomes -21.6 + 135, or 113.4.

The closest result to the height of the ball after 2.1 seconds is 113 feet.

Step-by-step explanation:

Drag the empty jar to the lake to get a water sample  

2. Fill two beakers with 600 ml water from the jar

3. Put the “1” and “2” labels on each beaker  

Take the pH meter to Beaker 1 and record the pH and description in Table A  

Take the pH meter to Beaker 2 and record the pH and description in Table B

 Add 1 unit of each base (soap, alkaline batteries, baking soda) to Beaker 2 and record the pH and description in Table B, and clear

This means that my hypothesis at the beginning was correct, more of m/s means KE will increase proportionally because they are all linear. I found it surprising when the bean bag height went over the water bottle drop mark.  

4.     To conclude, my hypothesis matched my data. The data values went up when more mass or speed was added. This means if I were in a situation where I needed more kinetic energy for something, I would know to increase mass or the speed of the object giving it energy.  

The reason that this hypothesis is correct is when you have more mass, you have more energy. So, when you drop let's say a baseball, it isn’t that heavy so it would only launch the bean bag so far. But a bowling ball is very heavy and has lots of energy when falling because of that, it would make the bean bag go very high.  

To make this experiment better, I would use a smoother material for the lever so energy wouldn’t be lost by friction from wood rubbing together. Also, maybe a scanner or video camera to more accurately record how far the bean bag went. All of these would help the lab get more precise results, maybe they could be used in a future lab.

Which number is rational?<br> GIVING OUT BRAINLIEST!!
mojhsa [17]

Answer:

The 4th option.

Step-by-step explanation:

Rational numbers are numbers which can be expressed as a fraction. Irrational numbers are numbers which can't be expressed as a fraction. Square root 16 is a perfect square so it is a rational number.
