16. The students decide to investigate how the mass of each marble affects its kinetic
energy. The students will roll each marble down the first hill on the track. They will
then compare the results for the kinetic energy of both the ceramic marble and the
steel marble.
Which figure best compares the kinetic energy of each marble when the marbles
roll down the hill on the track?
Answers
The ceramic marble has half the mass of the steel marble, the kinetic energy increases with increasing mass, hence the correct option is B.
What is kinetic energy?The form of energy that an object has as a result of its motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.
The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it.
Due to the fact that kinetic energy is related to the square of the speed, doubling the speed results in a four-fold increase in kinetic energy. The momentum does double with a speed increase, as we will discuss in the following lesson.
Therefore, the ceramic marble has half the mass of the steel marble, the kinetic energy increases with increasing mass.

Answer: the answers are 1. They are vestigial structures that once performed... 2. imprints of leaves or footprints... 3. homo erectus... 4. the early stages of embryo... 5. a close evolutionary connection between humans and many other mammals
Explanation: 100% correct as of april 2022
Human embryo have many characters that disappear during their growth. Tail bone is vestigial in humans, they have hair and produce milk indicates that these are mammal.
What is mammal?Mammals are the animals that have some unique feature like giving birth to young once, have mammary gland, having body hair, etc.
The appearance of tail in mammals just like fish, amphibians shows evolution.
Humans have hair and mammary gland which produce milk to nourish the young means they belongs to mammals.

Which of these is the most likely consequence of rising petroleum prices?
A. Increased interest in public transportation
B. Falling transportation costs
C. Lower gasoline prices
D. Less demand for electric cars
Answers
Answer: Increased interest in public transportation
Explanation: got it right
Due to public transportation, more vehicles need more petroleum, leading to an increase in petroleum prices, hence option a is correct.
How are petroleum prices rising?Petroleum prices are likely to have risen as a result of both increased demand and worries about supply interruptions. Global demand for oil has been rising, exceeding any increases in supply and surplus capacity.
One major reason is that developing countries, particularly China and India, have been quickly rising. These economies have grown more industrialized and urbanized, contributing to an increase in global demand for oil.
This is because transportation costs will rise, raising the prices of numerous commodities. This is cost-push inflation, as opposed to inflation produced by increased aggregate demand excess growth.
Therefore increased interest in public transportation, leads to rising petroleum prices, hence option a is correct.

How do matters differ and what explains that differences?
Answers
What is matter?
~ Matter is something which all physical objects are believed to be made of -- it is a material substance that occupies space, possesses mass, and is made up mostly of atoms (basic unit of matter) which consists protons, neutrons, and electrons, that constitutes the observable universe.
The states of matter~ State of matter is the distinction or the difference in forms of matter we can observe in our daily life. The 5 states of matter thus far are; solid, liquid, gas, plasma, and bose-einstein condensate.
DifferencesMatters differ in characteristics, appearance and compositions. Written here are the basic differences in 3 most fundamental states of matter.
Solid - a matter which composed of rigid and closely packed particles -- particles move only via vibrations. Has definite shape and definite volume.
Liquid - particles can move back and forth, not too tightly packed -- has definite volume but with no definite shape.
Gas - the particles in gas are relatively far apart compared to solid and liquid, they're moving fast back and forth/side to side, and bouncing nonstop. Gas neither have definite shape nor volume, and is way compressible than solid and liquid.
