Answer:

Forces come in pairs, so the force of gravity (9.8 N) with the mans weight (794N) on the earth is counteracted with the normal force ( the force of the earth back on the man) which is the same

Explanation:

Forces are available in pairs, so the force of gravity (nine.8 N) with the man's weight (794N) on the planet is counteracted with the everyday force ( the pressure of the earth again on the man) that's identical.

Gravitational force is a pressure that draws any items with mass. We name the gravitational force appealing as it constantly attempts to tug loads collectively, it never pushes them apart. In reality, every item, together with you, is pulling on each other objects inside the complete universe.

Explanation:

The speed of the tsunami waves was approximately 222 m/s (meters per second) or 800 km/h (kilometers per hour). This high speed contributed to the devastating impact of the waves, resulting in the loss of more than 200,000 lives.

Tsunami waves are caused by the displacement of a large volume of water due to underwater earthquakes, volcanic eruptions, or landslides. In this case, the earthquake off the coast of Sumatra triggered the tsunami. When the earthquake occurred, it generated a series of waves that radiated outward from the epicenter.

Satellites observing the waves from space measured the distance between wave crests to be 800 km and the period between waves to be 1.0 hour. To calculate the speed of the waves, we can use the formula: Speed = Distance / Time. In this case, the distance between wave crests is 800 km, and the time between waves is 1.0 hour.

Converting the time to seconds (1 hour = 3600 seconds) and the distance to meters (800 km = 800,000 meters), we can calculate the speed. Speed = 800,000 meters / 3600 seconds = 222 m/s. To convert this to kilometers per hour, we multiply the speed by 3.6, resulting in 800 km/h.

The high speed of the tsunami waves played a significant role in the widespread devastation caused by the event. As the waves traveled across the ocean, they maintained their energy and gained momentum. When the waves reached the coastal areas, their immense speed allowed them to propagate far inland, engulfing everything in their path with tremendous force.

Answer:

25.8 m/s

Explanation:

Initial Velocity (u) =?

Final velocity before it starts to fall ; v = 0

Distance (S) = 34 meters

Using the relation :

v² = u² + 2aS

a = - 9.8 m/s²

0 = u² + 2(-9.8)(34)

0 = u² - 666.4

u² = 666.4

u = √666.4

u = 25.814724

Hence, vertical velocity when the rock leaves her hand is 25.8 m/s

The amusement park ride begins with the passenger compartment at rest at point A. As it moves along the track to point B, the compartment is in free fall due to gravity. The distance between points A and B is 3R/4.

The force acting on the passenger compartment is gravity, which causes it to accelerate downward as it moves from point A to point B. Once the compartment reaches point B, it is no longer in free fall and the force acting on it is centripetal force, which keeps it moving in a circular path along the arc. The dimensions of the passenger compartment are negligible compared to R, which means that its mass can be considered to be concentrated at a single point. This simplifies the calculations involved in determining the ride's motion.

When the passenger compartment is released from rest at point A, it is in free fall between points A and B, which are 3R/4 apart. During this free fall, the gravitational potential energy is being converted into kinetic energy. As it moves along the circular arc of radius R between points B and D, the compartment's speed is determined by the conservation of mechanical energy.

Newton used Kepler's laws of planetary motion and astronomical observations to demonstrate that the gravitational force between two objects is inversely proportional to the square of the distance between their centers.

Sir Isaac Newton studied Kepler's three laws of planetary motion. Kepler’s second law describes how planets move faster when they are closer to the sun. It has been discovered that the gravitational force between two masses is inversely proportional to the distance between them squared, and that the law of universal gravitation governs the gravitational attraction between masses. In long answer, the following observational data might Newton have used to determine that gravitational force is inversely proportional to the distance squared between the centers of the objects:

Kepler's laws: Kepler's first law, which states that planets travel in elliptical orbits around the sun, is a significant foundation of Newton's law of gravity. Kepler's third law states that there is a relationship between a planet's distance from the sun and its orbital period. The distance between the sun and a planet increases with the square of its orbital period.

Astronomical observations: Newton conducted extensive astronomical observations to investigate and refine Kepler's laws. He measured the gravitational pull on objects at different distances from the earth. These measurements showed that the gravitational force decreases as the square of the distance between the objects increases. The force of gravity that pulls objects towards each other is inversely proportional to the distance between them squared.

In short, Newton used Kepler's laws of planetary motion and astronomical observations to demonstrate that the gravitational force between two objects is inversely proportional to the square of the distance between their centers.

As the pressure ratio rises, the thermodynamic efficiency of the Brayton cycle stays the same.

The Brayton cycle is a thermodynamic cycle commonly used in gas turbine engines, such as jet engines and power plants. It consists of four processes: intake/compression, combustion, expansion, and exhaust.

The thermodynamic efficiency of the Brayton cycle is given by the ratio of the net work output to the heat input. Mathematically, efficiency (η) is defined as η = (work output / heat input). In the Brayton cycle, the net work output is proportional to the difference in enthalpy (H) between the exit and inlet states of the compressor and turbine, while the heat input is proportional to the enthalpy change in the combustion process.

The pressure ratio in the Brayton cycle is the ratio of the exit pressure of the compressor to the inlet pressure of the compressor. As the pressure ratio increases, the compression process becomes more efficient, resulting in higher pressure and temperature at the turbine inlet. This, in turn, leads to an increase in the expansion work output. Simultaneously, the heat input also increases due to the higher temperature at the turbine inlet.

Since the net work output and heat input increase proportionally with the pressure ratio, the thermodynamic efficiency, defined as the ratio of these two quantities, remains constant. Therefore, as the pressure ratio rises in the Brayton cycle, the thermodynamic efficiency stays the same.

Joe was experiencing sensory adaptation, while individuals with damage to their visual cortex who could still identify object sizes were engaging in parallel processing. Sally is likely using a visual cliff apparatus to study children's fear of heights.

Joe's experience of not noticing a difference in the weight of the bag of leaves until the end suggests sensory adaptation. Sensory adaptation is the phenomenon where our sensory receptors become less responsive to constant or repetitive stimuli over time. In this case, Joe initially claimed the bag of leaves was not heavy because his sensory receptors adapted to the weight. However, when he noticed a sudden change in weight, he attributed it to the presence of rocks, indicating a difference threshold.

In the second scenario, individuals with damage to their visual cortex should theoretically not be able to see objects presented to them because the visual cortex plays a crucial role in processing visual information. However, when they were able to identify which cup was larger, it indicates that the brain engages in parallel processing. Parallel processing is the ability of the brain to simultaneously process multiple aspects of a stimulus or task. In this case, even though the individuals' visual cortex was damaged, other visual processing pathways or areas in the brain were able to contribute to the identification of object sizes.

Sally's use of a device to determine if children will continue to crawl past a visible edge suggests that she is using a visual cliff apparatus. The visual cliff apparatus is a device used in psychological studies to assess depth perception in infants and young animals. It typically consists of a glass or  plexiglass surface with a visible drop-off, creating the illusion of a cliff. By observing the behavior of children when faced with the visual cliff, researchers can gain insights into their perception of heights and their fear response. The visual cliff apparatus helps to assess if children have developed depth perception and if they perceive the visible edge as a potential danger.

K = 60 - 0/0.3 - 0.2

K = 60/0.1

K = 600 N/m

We want to find the value of the diameter that corresponds to the top 45% of the distribution.

To find this value, we need to calculate the z-score corresponding to the top 45% of the distribution. The z-score represents the number of standard deviations a value is from the mean. We can use the z-table or a statistical calculator to find the z-score associated with a cumulative probability of 0.45.

In this case, the z-score is approximately 1.645. Using the formula z = (x - μ) / σ, we can rearrange it to solve for x (the diameter we are looking for).
