it transfers heat to the hair to make it dry with the hot air which would be thermal energy
Answer:
<em>4, A proton in a particle accelerator moves faster and faster.</em>
Explanation:
A particle accelerator according to Wikipedia.com is a machine that uses electromagnetic fields to propel charged particles to very high speeds and energies, and to contain them in well-defined beams. Large accelerators are used for basic research in particle physics.
As the proton moves around, it collides with other proton and the wall of the accelerator thereby undergoing net interaction.
Answer:
The emf and internal resistance of the battery are 9 volt and 2.04 Ω
Explanation:
Given that,
First resistor
Power
Second resistor
Power
We need to calculate the emf and internal resistance
Using formula of emf

For first resistor
....(I)
For second resistor
.....(II)
From equation (I) and (II)

Using component of dividend rule


Now, Put the value of internal resistance in equation (I)




Hence, The emf and internal resistance of the battery are 9 volt and 2.04 Ω
Main components are lipids, proteins, and carbohydrates
