Answer:
- <em>Stored chemical energy is converted to mechanical energy.</em>
Explanation:
A <em>battery</em> posses <em>chemical energy</em>: this is chemical potential energy, which means that it is stored in the chemical bonds of the compounds in the battery. When the compounds in the battery react some bonds are broken and others are formed; at the end some energy is released and electricity is produced.
So, the chemical energy is first transformed into electrical energy.
A motor in the toy is able to transform that electrical energy into motion of gears and axes, which is how the wheels can spin. This motion of gears, axes and wheels is mechanical energy (kinetic energy).
Then, as you see, in that way the stored chemical energy in the battery is transfered to mechanical energy of the toy as it <em>rolls across the floor</em> thanks to the spin of the wheels.
<u>Answer:</u> The wavelength of light is
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant =
= Final energy level = 3
= Initial energy level = 6
Putting the values in above equation, we get:
Hence, the wavelength of light is
Answer:
<h2>15 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
3000 g = 3 kg
We have
net force = 3 × 5 = 15
We have the final answer as
<h3>15 N</h3>

Answer:
C2= 0.16M
Explanation:
C1= 2M, V1= 20ml, C2= ?, V2= 250ml
Applying dilution formula
C1V1= C2V2
2×20 =C2×250
C2= 0.16M
