But I don't think they determined how old it is, how would the dinosaurs that lived in water swim or any drink water. I don't know if this helps but hopefully it does. Also scientist have made advanced tech that could help with the age determination of the ocean floor.
A 55.0-kg skydiver free falls for a period of time before opening his parachute. What is his kinetic energy when he reaches a velocity of 16.0 meters/second?
7,040 J
440 J
539 J
cannot be determined without knowing his height above the ground
Given:
Mass of the skydiver:55 Kg
Velocity of the skydiver (v): 16m/s
Kinetic energy= 1/2mv^2
Kinetic energy= 1/2(55x16x16)
Kinetic energy= 7040J
Final answer:
The kinetic energy of a 55.0-kg skydiver reaching a velocity of 16.0 m/s is calculated using the equation KE = 1/2 mv², resulting in an energy of 7,040 Joules.
Explanation:
The question is asking to calculate the kinetic energy of a 55.0-kg skydiver who reaches a velocity of 16.0 m/s. Kinetic energy (KE) can be found using the equation KE = 1/2 mv², where m is mass and v is velocity.
Let's insert the values into the equation:
KE = 1/2 × 55.0 kg × (16.0 m/s)²
KE = 1/2 × 55.0 kg × 256 m²/s²
KE = 27.5 kg × 256 m²/s²
KE = 7040 Joules
Therefore, the kinetic energy of the skydiver when he reaches a velocity of 16.0 m/s is 7,040 J.
conductive deafness occurs Because of damage to what part of the body
Blank have a definite shape and do not easily take the shape of their container
Explanation:
An object whose particles are held by strong intermolecular forces of attraction is known as a solid substance.
In solids, particles have least kinetic energy and they can only vibrate at their position.
Therefore, solids have a definite shape and volume.
Hence, when we place a solid object in a container then it is unable to take the shape of container because its molecules are held strongly with each other.
Thus, they bond between its molecules cannot be broken down easily.
How will day and night change if earths rotational speed is decreased by 25%? Please answer good. Will mark brainliest.
If Earth's rotational speed decreased by 25%, then it would take 25% longer to rotate once.
-- A full cycle of day and night would take (1.25) x (24 hours) = 30 hours.
-- The average length of daylight/darkness over a whole year would be 15 hours each.
-- Daytime-high temperatures would be hotter everywhere, because the sun would be up longer. Night-time-low temperatures would be colder, because the sun would stay down longer.
-- Changes in the weather would be more drastic, and winds would generally be stronger, because of the greater contrast between warm areas and cold areas. BUT ...
-- High-pressure areas, low-pressure areas, hurricanes, typhoons, tornadoes, water going down the drain, dust devils, and Foucault pendulums, would all spin slower, because of the decrease in the Coriolis force.
-- There would be only 292 days in a year.
-- Every star in the sky would rise almost 5 minutes later each night than it rose the night before.
-- On the average, the moon would rise every day 61 minutes later than it rose the day before. Once the moon rose, it would be in the sky for about 16 hours before it crossed the sky and set on the other side.
-- From one Full Moon to the next one would be only about 23.6 days.
-- Each crescent and gibbous moon phase would last only about 5.9 days, instead of about a week as it does now.
-- When you went to bed, you could stay there and veg out for 10 hours. But don't get excited yet ... Once you got out of bed, you couldn't go back for another 20 hours !
-- Instead of waking up hungry and crying to be fed 3 times during the night, newborn babies would do it 4 times every night. New mothers wouldn't like it at all.
-- The standard work day and the standard school day would probably each grow to 10 hours instead of 8 hours. Bummer.
A car traveled 330 miles in 6 hours. What is the average speed?
it is 55 mph that is ok
Final answer:
The average speed of a car that traveled 330 miles in 6 hours is calculated by dividing the distance by the time, resulting in an average speed of 55 mph.
Explanation:
To calculate the average speed of the car, we need to divide the total distance travelled by the total time taken for the trip. In this case, the car travelled 330 miles in 6 hours.
The formula for average speed is:
Average Speed = Total Distance ÷ Total Time
Inserting the given values into the formula:
Average Speed = 330 miles ÷ 6 hours = 55 miles per hour (mph)
This means the car's average speed was 55 mph on that particular trip.

Which statement describes why energy is released in a nuclear fusion reaction based on mass-energy equivalence? For large nuclei, the mass of the original nucleus is greater than the mass of the products. For large nuclei, the mass of the original nucleus is less than the mass of the products. For small nuclei, the binding energy of the lighter nuclei is greater than the binding energy of the heavier nucleus. For small nuclei, the binding energy of the lighter nuclei is less than the binding energy of the heavier nucleus.
Answer: Option (c) is the correct answer.
Explanation:
When two or more small nuclei combine together to form a larger nuclei then this process is known as nuclear reaction.
The smaller is an atom, the more energy it requires to release an electron. This energy is known as binding energy.
Thus, when two small nuclei fuse together then there will be more binding energy as compared to when two large nuclei fuse together.
For example, fusion of two hydrogen atoms release more energy then one helium atom, and upon binding excess energy is released into the space.
Hence, we can conclude that energy is released in a nuclear fusion reaction based on mass-energy equivalence because for small nuclei, the binding energy of the lighter nuclei is greater than the binding energy of the heavier nucleus.
Final answer:
Energy is released in a nuclear fusion reaction because the mass of the original nucleus is greater than the mass of the products. This is due to mass-energy equivalence and the conversion of mass into energy.
Explanation:
In nuclear fusion reactions, energy is released because the mass of the original nucleus is greater than the mass of the products. This is based on the concept of mass-energy equivalence, as described by Einstein's equation E=mc². The missing mass in the reaction is converted into energy, and the products of the fusion reaction have a greater binding energy per nucleon (BE/A). Therefore, the larger nucleus formed in the fusion reaction has a greater binding energy and less mass per nucleon, resulting in the release of energy.

Define kinetic energy and thermal energy. Describe what happens to each as the temperature of the substances increases
Kinetic energy is the amount of energy a object has while it's in motion, and thermal energy is heat energy. In this case when the heat rises in substances for example a solid it will transform into a liquid causing the molecules to move faster which is a increase of kinetic energy. So the answer is "when the heat in substances increase the kinetic energy increases."
Hope this helps!
Answer:
All matter is made up of particles that are constantly moving. The motion of the particles results in kinetic energy. The part of total internal energy that can be transferred is thermal energy. As temperature increases, the particles in a substance move faster and have greater kinetic and thermal energy.

Stars exhibit a diverse range of temperatures and luminosities, determining their colors and types. The HR Diagram helps classify them, with main sequence stars like the sun, high-temperature blue supergiants, low-temperature red dwarfs, and evolved stars such as white dwarfs and red supergiants, showcasing the rich tapestry of stellar evolution.
5 - The color of the stars with the highest surface temperature is blue.
Stars emit different colors of light depending on their temperature. Higher temperatures, like those of blue stars, result in shorter wavelengths, while lower temperatures, like those of red stars, result in longer wavelengths.
6 - The color of the stars with the lowest surface temperature is red.
Red stars generally have lower surface temperatures, and they emit light at the longer, red end of the spectrum.
7 - The color of the stars from hottest to coldest is: blue, white, yellow, orange, red.
The sequence represents the color of stars from the hottest (blue) to the coolest (red). White stars fall between blue and yellow.
8 - Most of the stars on the HR Diagram are classified as main sequence stars.
The Hertzsprung-Russell (HR) Diagram is a graph of stars' luminosity (brightness) against their surface temperature. Most stars, including our Sun, fall into the main sequence category, where they spend the majority of their lives.
9 - The type of star that has a high temperature but a low luminosity is a white dwarf.
White dwarfs are hot but have low luminosity because they are small and no longer undergoing nuclear fusion in their cores.
10 - The type of star that has a high temperature and high luminosity is a blue supergiant.
Blue supergiants are massive stars with high temperatures and luminosities. They are in the later stages of their evolution and have expanded in size.
11 - The type of star that has a low temperature but high luminosity is a red supergiant.
Red supergiants are large, cool stars with high luminosities. They are in the late stages of their evolution.
12 - The type of star that has low temperature and low luminosity is a red dwarf.
Red dwarfs are small, cool stars with relatively low luminosities. They are the most common type of star in the universe.

A proton has a mass of 1.672 X 10-27 kg. What is its weight?
Protons are usually regarded by their mass, as mass is not specific to any gravitational acceleration. However, if you wished to find the weight of a proton on Earth, it would be:
Force (weight) = mass of proton * acceleration due to Earth's gravity
F = ma
F = (1.62 x 10^-27)(-9.8)
F = 1.5876 * 10^-26N
Final answer:
The weight of a proton can be calculated using the formula W = mg, where W is weight, m is mass, and g is the acceleration due to gravity. Using the given mass of the proton and the acceleration due to gravity on Earth, we can calculate its weight to be approximately 1.64 x 10^-26 N.
Explanation:
The weight of an object is the force exerted on it due to gravity. The formula to calculate weight is W = mg, where W is the weight, m is the mass of the object, and g is the acceleration due to gravity. In this case, the mass of the proton is 1.672 x 10-27 kg.
To calculate the weight of the proton, we need to know the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s2. Using this value, we can calculate:
W = (1.672 x 10-27 kg) x (9.8 m/s2) = 1.64 x 10-26 N
Therefore, the weight of the proton is approximately 1.64 x 10-26 newtons.

on a roller coaster ride at an amusement park, a car travels from 7.6 m/s to 56 m/s in 3 seconds. whats the cars acceleration?
a) no acceleration
b) 11 m/s^2
c) 235 m/s^2
d) 16 m/s^2
Acceleration is defined as rate of change in velocity
So we can write its formula as
[tex]a = \frac{v_f - v_i}{t}[/tex]
here we know that
[tex]v_f[/tex] = final velocity = 56 m/s
[tex]v_i[/tex] = initial velocity = 7.6 m/s
t = time interval to change the velocity = 3 s
now we will plug in all values in the above equation
[tex]a = \frac{56 - 7.6}{3}[/tex]
[tex]a = \frac{48.4}{3}[/tex]
[tex]a = 16.13 m/s^2[/tex]
so here roller coaster will accelerate at rate of 16 m/s^2 and hence correct answer is "option d"

c. energy being destroyed
d. one form of energy being converted to another
A. elastic motion because that's the answer
The given statement is an example of one form of energy is being converted to another
Answer: Option D
Explanation:
A car is is stopped due to the application of brakes to bring it back to rest. This is an example of kinetic energy as work is done to stop the car. When brakes are applied, heat is produced due to the friction between the wheels and the brakeshoes which is an example of heat or thermal energy. Hence kinetic energy is transformed into thermal energy in this application.
