<span>Data organization is extremely important in science. One must be able to display data in a way that others can look at it and easily understand what's being said. This takes us to line charts, which are great for showing how something increases or decreases over an amount of time. Another example would be a pie chart which could show the percentages of different matter that makes up a full object.</span>

Answer:
No, not at all. This kinetic energy of car is converted/lost in the form of sound and heat under the tyre when driver apply brakes.
Explanation:
This law states that energy can neither be created nor destroyed but it changes from one form to the other.
In this case reduction of kinetic energy of car does not contradict the law but it changes into heat and sound energy. When driver apply brakes we hear the sound of Tyre due to friction with the road. The tyre become hot too.
So it is not in contradiction to the law of conservation of energy (First Law of Thermodynamics).

Answer:
27.22 F.
Explanation:
T ( t ) = T₀ + ( T₁ - T₀)
T ( t ) = 41 , T₀ = 0 , T₁ = 140 , t = 15
Put these values in the equation above
41 = ( 140 - 0 ) e^{-15k}
41/140 = e ^{-15k}
(41/140)^{1/3} = e ^{-5k}
Let after 20 minutes temperature becomes T
T = 0 + 140 e^{-k20}
T / 41 = e^{-5k }
= (41/140)^{1/3}
T = 41 X (41/140)^{1/3}
= 27.22 F.
Answer: One thing magnetism and electricity have in common is that they are related.
Explanation: Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow.
