There was a head-on collision between a compact hybrid car and a SUV.
According to Newton’s 3rd law, the force exerted on each other is the same.
So, why are people in the smaller car more likely to get injured than those in the large one, assuming both cars are equally strong?
Vocabulary: inertia, mass, acceleration, force, unbalanced, balanced, Newton's 2nd Law
Answer:
hey im back
Explanation:
The reason behind why people in the smaller car are more likely to get injured than those in the large one is greater acceleration of the small car.
What is acceleration?Acceleration is rate of change of velocity with time. Due to having both direction and magnitude, it is a vector quantity. Si unit of acceleration is meter/second² (m/s²).
When There was a head-on collision between a compact hybrid car and a SUV, according to Newton’s 3rd law, the force exerted on each other is the same. But .
As from Newton's 2nd Law, we know that numerical value of force is simply multiplication of mass and acceleration. So, due to having small mass, smaller car suffers more acceleration for same amount of unbalanced force.
This acceleration acts against current inertia of motion of both cars and try to change it. As small car has greater acceleration, people in the smaller car are more likely to get injured than those in the large one although both cars are equally strong.

Alika finds a certain kind of butterfly near her house. She reads that ultraviolet light is absorbed by the butterfly’s wings, red light is transmitted through the butterfly’s wings, and green light is reflected off the butterfly’s wings. Alika’s friend Claire tells her that if you shine a light on the butterfly, its wings will glow.
Can light cause the butterfly’s wings to glow? Why or why not? Does it matter what type of light Alika shines on the butterfly?
No, light can't cause the butterfly's wing's to glow. Explanation: Butterflies contain wings which are of different colors for attractiveness and also to show warning alarm for it's predator.
Answer:
Hello! I hope this answer can help future amplify goers. I know it is not perfect, but you can definitetly base your answer off of mine if you like. If you need some encouragement for finishing, you got this!!!! I know these are annoying and sometimes tough, but you can do it! you'll get through this just fine :) now for the actual answer:
Yes, light can cause the butterfly's wings to glow. This is because the UV light is absorbed by the butterfly's wings, and when the light gets absorbed, it gives the wings energy. The increase in energy will cause the butterfly wings to change color. Not all light will make the wings glow, however. Only UV light will do the trick. This is because as the text says, the green light is reflected off the butterfly's wings, which means it will not gain any energy from visible light. In conclusion, light can cause the butterfly's wings to glow, since UV light is absorbed by the wings, meaning it gets energy. It matters what type of light is shone on the wings since visible light is reflected, while UV light will absorb.
I really hope that helps you! if you have any questions you can ask me about it in a comment

Define the following terms: a) Heating effect of electric current b) Magnetic effect of electric current. c) Electric fuse. d) Transpiration e) Electromagnet
Answer:
A.) When an electric current is passed through a conductor, it generates heat due to the hindrance caused by the conductor to the flowing current. The work done in overcoming the hindrance to the current generates heat in that conductor.
B.) The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect
C.) An electric fuse is an electric device which interrupts the flow of current in an electric circuit. It is installed in a circuit to stop the flow of excessive current. A fuse is usually a short piece of wire. Normally an alloy of tin and lead is used as the fuse wire, as it has high resistivity and low melting point.
D.) the act or process or an instance of transpiring especially : the passage of watery vapor from a living body (as of a plant) through a membrane or pores.
E.) An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil.

How might the distance between the needle and the water droplets have affected the movement of the droplets?
(8th Grade Science) Please help
Answer:
The behavior of droplets trapped in geometric structures is essential to droplet manipulation applications such as for droplet transport. Here we show that directional droplet movement can be realized by a V-shaped groove with the movement direction controlled by adjusting the surface wettability of the groove inner wall and the cross sectional angle of the groove. Experiments and analyses show that a droplet in a superhydrophobic groove translates from the immersed state to the suspended state as the cross sectional angle of the groove decreases and the suspended droplet departs from the groove bottom as the droplet volume increases. We also demonstrate that this simple grooved structure can be used to separate a water-oil mixture and generate droplets with the desired sizes. The structural effect actuated droplet movements provide a controllable droplet transport method which can be used in a wide range of droplet manipulation applications.

You read that light waves travel through air and water at different speeds. What is one way this can affect what you see around you?
Answer:
light waves slow down in water.
Explanation:
light can reflect off of different surfaces, and in water they slow down.
for example, in a completely black room, the light cannot bounce/reflect off of the walls, that's why it is so dark.
hope this helps!
The Light travels faster in air than it travels in water.
The speed of light decreases when it enters from a rarer medium to denser medium and increases when it enters from a denser medium to rarer medium. Therefore, the speed of light increases when light ray passes from water to air and the speed of light decreases when light ray passes from water to glass.When the light wave moves from air to water, it slows down. This change in speed causes the light wave to bend.Learn more:

a
It travels left at a constant speed.
b
It travels left at an increasing speed.
c
It travels right at a constant speed.
d
It travels right at an increasing speed.
The motion that best describes the statement in the question will be that it travels to the left at an increasing speed. Hence, option B is correct.
What is Force?A force in physics is an input that has the power to change an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe forces. Being such a vector quantity, a force does have magnitude and direction. The SI unit metric newton is used to measure it (N). The letter F stands for force.
According to Newton's second law's original formulation, an object's net force is equal to the speed that its momentum is changing over time.
As per the given information in the question,
The first student pushes the engine to the right with a force of 2 N.
The second student pushes the engine to the left with a force of 5 N.
So, the net force will be,
5 N - 2 N = 3 N, towards the left side.

Answer:
None.
Explanation:
Molecules are formed by an element's need or excess of electrons. For example, in nature oxygen generally exists as 02. Other molecules are formed via chemical reaction. The example here is the burning of gasoline. Gasoline's two main byproducts are water and carbon dioxide.
Hydrogen as an atom has one electron making it unstable. Put a second hydrogen atom next to the first and the two atoms will share electrons to fill the first energy level the atom needs to be stable.
