Explanation:
why is it difficult for a car to round a curve at high speed
Answer:
Because the force required to produce this acceleration equals the mass of the car x acceleration, the group of the car is the same but the acceleration is a lot more hence a much bigger force is required. So this is why it's harder for cars to corner at a high speed rather than lower.
Answer:
Vehicles are heavy and have a lot of inertia. This means that if you drive too fast on a curve, your vehicle will keep going straight instead of going around the curve, no matter how hard you drive or slow down to keep it in your lane. Centrifugal force creates a strong outward pull on your vehicle. So all you need to do is slow down before entering a corner. Reducing your speed when you are already on a bend can cause your car to skid.

You left some papers on a picnic table in the park on a windy, sunny day. When you returned, the papers were scattered all over the park. What can you conclude about the flow of energy in this situation?
The heat energy from the sun was transformed to sound energy, which moved the papers.
The heat energy from the sun was transformed into kinetic energy, which moved the papers.
The mechanical energy in the wind was transferred to the papers, which caused the papers to move.
The mechanical energy in the wind was transferred to the table, which caused it to shake and move the papers.
Answer: Option c
Explanation: Wind has kinetic energy to move objects from their places. It is vastly used across the world for the production of electricity.
By turning the kinetic energy of moving air into electrical, the wind is used to generate power. Wind drives the rotor blades of contemporary wind turbines, which transform kinetic energy into rotational energy. A shaft transmits this rotational energy to the generator, which generates electrical energy. More than a century ago, the first wind turbines appeared. After the electric generator was developed in the 1830s, engineers began experimenting with harnessing wind power to create electricity. However, modern wind power is thought to have been invented in Denmark, where horizontal-axis wind turbines were built in 1891 and a 22.8-meter wind turbine started operating in 1897. Wind power generation occurred in the United Kingdom and the United States in 1887 and 1888.

The air currents across the continents would determine the distribution of the air.
What are air currents?Air currents across the continents are primarily driven by temperature differences and the rotation of the Earth. The warm air near the equator rises and flows towards the poles, while the cooler air near the poles sinks and flows towards the equator.
This creates large-scale circulation patterns known as Hadley cells, Ferrell cells, and Polar cells. These cells are responsible for the trade winds, westerlies, and easterlies, respectively. Additionally, there are also local winds caused by differences in terrain, such as sea breezes and valley breezes.

What two gases in the atmosphere do animals and plants need to breathe and grow?
Answer: Explanation:
Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.
Which of the following is an example of an unbalanced force?
(A) A ball on the grass
(B) A book sitting on a table
(C) A chair leaning on the wall
(D) A stroller being pushed
Answer:
d
Explanation:
because the motion is changing as it slows down mark brainliest to help me out :)
The example of an unbalanced force is a stroller being pushed. The correct option is D.
What is unbalanced force?An object is said to be acted upon by an unbalanced force only when an individual force is not balanced by a force of equal magnitude and direction.
Unbalanced forces are caused by a forward force or thrust and a frictional force opposing each other.
Friction is an opposing force to motion. It occurs whenever two surfaces rub against each other, such as when you rub your hands together or apply the brakes on a bike or car.
Forces that are balanced are those that are opposite in direction and equal in size.
Equilibrium is defined as the presence of balanced forces. There is no change in direction when forces are balanced.
As here pushing a stroller is not balancing the force as the force applied is more than the opposing one.
Thus, the correct option is D.

Explain how Galileo proved that his model was correct and that Ptolemy’s was not correct.
Answer:
Written below.
Explanation:
Despite his many attempts, Galileo could not prove that the earth went around the sun. However, he was able to prove that the Ptolemaic model was incorrect, after he made telescopic observations of Venus. He discovered that Venus went through a full set of phases, like our moon. This could only happen if Venus went around the sun. In the Ptolemaic model, Venus does not go around the sun, and so would not go through all the phases. The diagram below shows how Venus would only go through crescent phases in the Ptolemaic model. (Recall that the phase of Venus will depend on the relative positions of the earth, Venus and the sun.)
In order to see a "full" Venus, the sun must be between the earth and Venus. A "gibbous" Venus is when the sun is sort of between the earth and Venus. When Venus is at its greatest elongation from the sun, then we would see it as a "half." When Venus was even closer to the earth, we would see it as a crescent. All these conditions happen only when Venus goes around the sun, as in the models by Copernicus and Brahe. In the Ptolemaic model, Venus is always between the earth and the sun, so would only show crescents. Even greatest elongation would not give a half Venus, because the triangle made between the sun, earth and Venus would not be a right triangle.
Galileo's studies of motion also led him to discover the basic idea of inertia. He finally figured out that if an object has a velocity, it will maintain that velocity without the need for any other forces. In fact, it takes a force in order to change a velocity. The reason why objects slow down unless they are pushed is that there is a frictional force that acts whenever two objects rub or slide across each other, and this frictional force is what causes things to slow down. As scientists finally began to accept Galileo's ideas of motion, then the big scientific reasons for rejecting a moving earth disappeared, leaving only the religious.
By this time Kepler had discovered that the planets actually orbitted the sun in an ellipse, but I am not sure why Galileo did not mention Kepler. It should also be noted that Brahe had proposed his own hybrid model of the solar system, with the sun orbiting the earth, and all the other planets orbiting the sun. Brahe's model did correctly explain the phases of Venus, and had the earth at rest in the center. For a while in the seventeenth century, the religious astronomers dumped Ptolemy, but clung to Brahe's as a possible model that kept the earth at rest. Science as a whole, however, had moved on and accepted the heliocentric model. Most scientists accepted the heliocentric theory not because there was proof that the earth moved, but because it was the "prettiest" model that explained the observations.
Galileo invented telescope and he observed the movement of planets around stars. From constant observations, he found the earth centric solar system model is wrong and all planet are revolving around sun making it heliocentric.
What were Galileo's contribution to heliocentric models?With the aid of his telescope, Galileo demonstrated that Venus experienced a full cycle of phases, just like the Moon. The first concrete observational evidence that was consistent with the Copernican system but not the Ptolemaic system was given by this observation, making it one of the most significant in human history.
The empirical finding that Venus is always close to the Sun in our heavens is key. As the enlarged image shows, Venus should therefore always be in crescent phase in the Ptolemaic system when observed from Earth because, as it revolves around its epicycle, it cannot ever be too far from the direction of the sun.
The Copernican system was primarily appealing because it simplified how the data were described, but this was the clearest proof yet that the Ptolemaic cosmos was not simply more flawed than the Copernican one.
