Theo mixes cake batter and places it in the oven at 350°F for 45 minutes. Explain what type of reaction baking a cake represents in terms of energy.
Answer:
Baking a cake requires heat to be applied to the batter in order for it to cook and chemically change into cake. The energy or heat applied is absorbed by the ingredients, so this represents an endothermic reaction.
Explanation:
that's the sample answer, hope it helps
The batter needs to be heated in order to cook and chemically transform into a cake when it is baked. An endothermic reaction is taking place because the energy or heat applied is being absorbed by the constituents.
What is energy?The quantitative characteristic that is transferred to a body or a physical system in physics is referred to as energy. It manifests itself as heat and light, as well as the act of doing work. Energy is a resource that is conserved; it can only be changed from one form to another and cannot be created or destroyed, according to the law of conservation of energy. The SI unit of energy measurement is the joule (J).
According to the question, there are various types of reactions two of which are endothermic reactions and exothermic reactions.
In an endothermic lot of energy is absorbed and in opposition to the exothermic reaction lot of energy is released.

Explanation:
Like olfactory cells that detect odors, auditory receptor cells (also called hair cells) are recessed from the surface of the body. ... Sound waves are converted into vibrations in a fluid in the inner ear, and these vibrations indirectly move the hair cells, which then send electrical signals to the brain.

How did Lavoisier's study of combustion prove that fire was not an element?
Answer:
In June 1783, Lavoisier reacted oxygen with inflammable air, obtaining "water in a very pure state." He correctly concluded that water was not an element.
Explanation:
As the fire left behind ashes of a substance it indicated that it is not an element as element cannot be decomposed in to simpler substances.
What is an element?It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

How much force (in Newtons) acts on a 1700 kg car going around a
80 m radius turn at a speed of 15 m/s?
a) 375
b) 4781
c) 1167
d) 319
Answer:
b) 4781 N
Explanation:
Because there is a redius do this question is talking about the acceleration force which= mv^2/r
so a=15^2/80=2.8125 m^2/s
so the force will be = m.a
F =1700×2.8125=4781.25 N
you push a block of 50kg with a force of 400 N over a distance of 8m. How much kinetic energy does the box gain?
Answer:
The box gains 3200 J of kinect energy.
Explanation:
What is kinect energy?Kinect energy is the energy of an object has because of its motion. Almost anything that has mass and it's in motion has kinect energy. Examples:
wind;throwing a footbal;driving a car;lauching a rocket;etc.What is the work energy theorem?Also known as the principle of work and kinect energy, it states that the work done by all forces acting upon an object equals the change of its kinect energy.
For example, if you pull a box, then you're exerting a force on it and it moves forward. Since the box has mass and it's in motion, you have changed its kinect energy.
Solution:
Write the data down:
[tex]\bullet \quad \mathsf{m=50\,kg}\\\\\bullet \quad \mathsf{F=400\,N}\\\\\bullet \quad \mathsf{d=8\,m}[/tex]
Apply work energy theorem:
[tex]\mathsf{W}= \Delta\mathsf{K}[/tex]
The amount work done equals the change of kinect energy:
[tex]\mathsf{W}=\mathsf{K-K_o}[/tex]
Since the block is at rest at the beginning, so it has zero initial kinect energy:
[tex]\mathsf{W}=\mathsf{K-0}\\\\\\\mathsf{W}=\mathsf{K}[/tex]
Now, apply the formula for work to the left hand side of the equation:
[tex]\mathsf{F\cdot d}=\mathsf{K}\\\\\\\mathsf{400\cdot 8}=\mathsf{K}\\\\\\\therefore \boxed{\mathsf{K=3200\,J}}[/tex]
Conclusion: the box has gained 3200 J of kinect energy.

A ball is kicked straight up from the ground with a speed of 10.0 m/s. How long will the
ball be in the air?
The total amount of time the ball would be in the air is 2.04 secs
To determine how long the ball will be in the air,
We will the equation for calculating total time of flight, T
For a projectile motion, the total time of flight of an object is given by
[tex]T = \frac{2usin\theta}{g}[/tex]
Where T is the total time of flight
u is the velocity of projection
θ is the angle of projection
and g is the acceleration due to gravity
From the question,
u = 10.0 m/s
θ = 90° (This is because the ball is kicked straight up)
Put these values into the equation,
[tex]T = \frac{2usin\theta}{g}[/tex]
[tex]T = \frac{2\times 10.0 \ sin90}{9.8}[/tex]
(NOTE: g = 9.8 m/s²)
∴ [tex]T = \frac{2\times 10.0 \times 1}{9.8}[/tex]
[tex]T = \frac{20}{9.8}[/tex]
T = 2.04 secs
Hence, the total amount of time the ball would be in the air is 2.04 secs

Sound waves travel at a speed of 330.0 m/s . How long does it take for the sound of thunder to travel 1.5 km ? (20points)
4.55 seconds
Step-by-step explanation:-Given, Speed = 330.0 m/s
To find the time, it will take for the sound of thunder to travel 1.5 km, we have to apply the formula for speed :
[tex]speed = \frac{distance}{time} [/tex]
This implies that:-
[tex]time = \frac{distance}{speed} [/tex]
So, Let's get started with the steps -
Step 1- Convert 1.5 km to metres.
[tex]1.5 \: km \: \\ = > \: 1.5 \times 1000 \\ = > 1500 \: m[/tex]
Step 2- Now, to get time, substitute the values you got now in "time=distance/speed"
[tex]t = \frac{1500}{330}[/tex]
[tex] => t = 4.55 \: seconds[/tex]
Therefore, the answer is 4.55 seconds

Sally has a car that accelerates at 5 m/s2. If the car has a mass of 1000 kg, how much force does the car produce?
Answer:
5000 NExplanation:
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 we have
mass = 1000 kg
acceleration = 5 m/s²
We have
force = 1000 × 5 = 5000
We have the final answer as
5000 NHope this helps you

what is the average acceleration of a car that is initially at rest at a stop light and then accelerates to 24 m/s in 9.4 s?
Answer:
Below
Explanation:
To find the acceleration of the car you can use this formula :
vf = vi + at OR a = v/t
I'm going to use the first one because it explains the steps more clearly :
vf = 24 m/s
vi = 0 m/s
t = 9.4 s
a = ?
24m/s = 0 + (a)(9.4s)
24m/s = a9.4
Divide both sides by 9.4
a = 2.55319 m/s^2
Round to 3 sig figs
a = 2.6 m/s^2
