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.
Answer:
Usually light years, or parsecs.
Explanation:
Answer:
Saturated hydrocarbons are the compounds containing only single covalent bonds. These are also known as alkanes. Unsaturated hydrocarbons are the straight chain compounds containing double or triple covalent bonds. These compounds are less reactive. . An unsaturated compound is a chemical compound that contains carbon-carbon double bonds or triple bonds, such as those found in alkenes or alkynes, respectively.

Answer:
Force of attraction = 35.96 N
Explanation:
Given: charge on anion = -2
Charge on cation = +2
Distance = 1 nm = m
To calculate: Force of attraction.
Solution: The force of attraction is calculated by using equation,
---(1)
where, q represents the charge and the subscripts 1 and 2 represents cation and anion.
k =
F = force of attraction
r = distance between ions.
Substituting all the values in the equation (1) the equation becomes
Force of attraction = 35.96 N
Answer:
When octane and oxygen gas are burned in our cars, carbon dioxide and water come out of the exhaust. The increase in carbon dioxide in the atmosphere is causing global warming. 4.
