Im going to guess on this one, and say that it is chemical.
Answer:
C more than 1 second
Explanation:
it will take time since its 4.9 meters and how hard you throw it down
Answer:50%
Explanation: put it you are in a hurry
Answer:
C. The voltage drop across the resistor is 2.1V and nothing about the current through the resistor.
Explanation:
When connected in parallel, voltage across the resistances are the same. So if 2.1V was dropped across the LED then 2.1V was also dropped across the resistor. However, this tells us nothing about the current through the resistor. We can find the current across the resistor if we know the resistance of the resistor, but that's about it.
If it were a series connection, then the current would have been the same, but the voltage drop were another story.
Answer:
a = 16 m/s²
General Formulas and Concepts:
<u>Dynamics</u>
Newton's Law of Motions
- Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion
- Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration)
- Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction<u>
</u>
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
[Given] F = 22000 N
[Given] m = 1375 kg
[Solve] a
<u>Step 2: Find Acceleration</u>
- Substitute in variables [Newton's 2nd Law of Motion]: 22000 N = (1375 kg)a
- Isolate <em>a</em>: 16 m/s² = a
- Rewrite: a = 16 m/s²
