Use The Diagram Below To Answer The Next 3 Questions. At Which Point On The Roller Coaster Will The Car

Answers

Answer 1
X
Because at that point the car will be travelling the fastest.
Answer 2

The point at which the kinetic energy of the car is maximum is point X because of the maximum speed of the car at this point.

What is kinetic energy?

Kinetic energy is the energy of motion. When an object is in motion, it possesses kinetic energy. It is defined as the energy that an object possesses due to its motion. The amount of kinetic energy an object has is dependent on its mass and velocity.

The formula for kinetic energy is KE = (1/2)mv², where KE is kinetic energy, m is the mass of the object, and v is the velocity of the object. This means that the greater an object's mass and velocity, the more kinetic energy it possesses.

Kinetic energy can be transformed into other forms of energy, such as potential energy or heat, through various processes.

C. The air moves from high to low pressure systems.
D. The heating of the earth’s surface does not affect pressure.
whoever gets it right gets brainilest!!!

SCIENCE

Answers

Answer:

The Air moves to high to low system.

Explanation:

I think because of hot temperature it is hot.

The correct statement about pressure distribution due to uneven heating of the earth’s surface is the air moves from low to high-pressure systems. The correct option is B.

What is pressure distribution?

Pressure distribution is sometimes different in different areas. This happens due to the uneven warmth of the earth. The uneven heating causes a difference in temperature and cause different pressure in areas.

Where there is a low temperature, the air pressure is higher. During uneven heating, the air blows from low to high-pressure systems. The uneven heating of the earth is due to the reason that water heat slower than the land. This causes air to warm and expand and rise.

Thus, the correct option is B. The air moves from low to high-pressure systems.

What is the average speed (mph) for a car journey of 140 miles that began at
9:30 am and finished at 12:00 noon?

Answers

Answer:

The car is going 60 miles per hour✔✔

Explanation:

The awnser is 56.


Reasoning:

9:30 AM to 12:00 PM is a difference of 2.5 hours (or 2 hours and 30 minutes). The equation to find MPH is D(distance) / T(time). Therefore, 140/2.5 = 56. Hope this helps!

Answers

Answer: comparing the amount of decayed and undecayed isotopes

Explanation:

The absolute age of the ingenious rock can be best determined by radiometric dating, which analyzes the amount of two different isotopes in the sample.

How absolute age of ingenious rock be determined?

Radiometric dating, which analyzes the amount of two different isotopes in a sample, is utilized to determine the age of rocks. Radioactive isotopes decay in a predictable way, enabling geologists to determine the age of a sample.

Using equipment such as this thermal ionization spectrometry. It can be determined by examining the position of rock strata. The absolute age of a stratum of rocks or fossils is its numeric age.

Radiometric dating can be employed to establish absolute age, the ingenious rock having aged years ago to determine absolute age.

Therefore absolute age of the ingenious rock is determined by radiometric dating, having different isotopes in the sample.

A group of students is investigating whether air resistance depends on the size of an object. The students throw two paper pieces each with the same force. One piece of paper is flat and the other is scrunched into a ball. The distance traveled by each paper piece is shown.


Experimental Observations
Student 1 Student 2 Student 3 Student 4
Distance traveled by flat paper 0.2 m 1.2 m 1.5 m 0.8 m
Distance traveled by scrunched paper 1.5 m 2.4 m 3 m 2 m
