Answer:
General Formulas and Concepts:
<u>Physics 1 - Newton's Law of Motion</u>
- Gravity: 9.8 m/s²
- Static/Kinetic Friction Formula:
- Free Body Diagram
Explanation:
<u>Step 1: Define Variables</u>
<u>Step 2: Find Normal Force</u>
<em>See Attachment for FBD.</em>
- Substitute: Fg = (12 kg)(9.8 m/s²)
- Multiply: Fg = 117.6 N
- Redefine: Fn = 117.6 N
<u>Step 3: Find Kinetic Friction</u>
- Substitute: Fs = (117.6 N)(0.6)
- Multiply: Fs = 70.56 N
I am pretty sure that B. How tall the corn grows is the dependent
The student is not a variable in how tall the corn grows, and the question does not indicate any different types of corn in this.
So the independent variable would be the type of fertilizer and the dependent variable would be the height of the corn.
I hope this is right and helps, have a good day!
Answer: B - The motion of lithospheric plates over millions of years.
Explanation:
<em>I'll supply a picture of proof-</em>
Where the question says "the four different positions", it's talking about
the four situations that are shown in the picture right next to the question.
The question can't be answered without seeing the picture.
