Answer is:
<span>Chemical → electrical → mechanical and sound
</span>
Explanation:
Let's take this step by step:
1- For the batteries to work, chemical reactions must occur within the battery itself. This is considered "chemical energy"
2- For the CD player to start operating, it needs electrical energy that is supplied from the batteries
3- When the CD player gains this electrical energy, it can then function correctly and play the songs producing mechanical and sound energies.
So, basically the flow goes as follows:
Chemical reactions within the batteries lead to the formation of electrical energy which operates the CD player producing mechanical and sound energy.

Answer:
118N
Explanation:
To find the weight, you must:
- Use the equation w = m × g
- m = 12kg and g = 9.8N
- So, you multiple 12 and 9.8, which is equal to 117.6
- You need to round it to the nearest whole number, which is 118
- The unit is N for newtons
Answer:
Explanation:
Let m be the mass of the object and v be the maximum velocity . The tension will provide centripetal force for the circular motion .
T = mv² / R where R is radius of circular path . T is tension .
putting the values given in the equation above
26.9 = m v² / 1
m v² = 26.9
kinetic enrgy = 1/2 m v²
= 26.9 / 2
= 13.45 J
13 J .
Maximum kinetic energy = 13 J .
Answer:
90/100%, 9/10%
Explanation:
These represent 9 of 10 parts.
Hope this answer helps you out.
The magnitude of average current is 2.02 * 10⁻¹⁴ A.
<h3 /><h3>What is current?</h3>
A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.
Number of electrons passing per second = 4910/ 0.0662 = 74169.18
Number of proton passing per second = 3485/0.0662 = 52643.50
current due to electrons,
I = ne
= 74169.18 * 1.6 * 10⁻¹⁹
= 1.18 * 10⁻¹⁴ A
current due to protons,
I = ne
= 52643.50 * 1.6 * 10⁻¹⁹
= 0.84 * 10⁻¹⁴ A
total current I = Ie + Ip
I =( 1.18 + 0.84 ) * 10⁻¹⁴ A
I = 2.02 * 10⁻¹⁴ A
