The image shows the relationship between temperature and speed of sound in air. The x-axis of the graph shows the temperature in degrees Celsius, and the y-axis shows the speed of sound in meters per second. The line on the graph shows that the speed of sound increases with temperature. For every 1 degree Celsius increase in temperature, the speed of sound increases by about 0.6 m/s.
The speed of sound in air is also affected by other factors, such as humidity and air pressure. However, temperature is the most important factor affecting the speed of sound.
The speed of sound at the lowest temperature in the image is 330.4 m/s, which is at -1°C.
The speed of sound at the highest temperature in the image is 358.0 m/s, which is at 45°C.
The temperature at which the speed of sound is slowest is -1°C.
The temperature at which the speed of sound is fastest is 45°C.
Yes, temperature affects the speed of sound. The speed of sound increases with temperature. This is because the molecules of a medium vibrate faster at higher temperatures, and this allows sound waves to travel more quickly.

3. Explain what forces the Egyptians had to overcome when building the pyramids
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
But how did the Egyptians overcome the extreme friction of dragging such massive things through the sandy desert, some of which weighed more than 9,000 pounds? Researchers at the University of Amsterdam have come up with a very simple solution to the friction problem: they utilised water.
The pyramids were not built by slaves, contrary to common perception. Archaeologists discovered the ruins of a purpose-built town for the hundreds of labourers who constructed the renowned Giza pyramids about 4,500 years ago.
The Egyptians had to overcome the force of friction while dragging the big blocks of stone and the force of gravity while uplifting the large stone structure to a greater height when building the pyramids.
What is friction?Friction is a type of force that resists or prevents the relative motion of two physical objects when their surfaces come in contact.
The friction force prevents any two surfaces of objects from easily sliding over each other or slipping across one another. It depends upon the force applied to the object.
Thus, while constructing the pyramids, the Egyptians had to fight against the forces of gravity and friction as they lifted the massive stone edifice to a greater height.

A murder has been committed and you are a juror at the trial. The prosecuting attorney has presented evidence that the victim put up a struggle and injured her assailant, drawing blood, prior to her demise. Blood typing was completed and the blood type matches the defendant's blood type. The prosecuting attorney states that this evidence is proof that the defendant is guilty of murder. As a juror, do you think the defendant is guilty of murder based on this evidence? Why or why not? If not, what other evidence do you think is needed?
The fact that the blood type matches that of the defendant is no proof that the defendant is guilty as charged.
There are about four blood types that people can have, these blood types are; A, B, AB and O. Everybody must posses one of these blood types. A person's blood type is determined through laboratory tests.
The prosecuting attorney was wrong in concluding that the defendant is guilty as charged only based on the blood type evidence. different people could have the same blood type. Only DNA analysis can conclusively prove that the defendant is actually guilty as charged.

What is a longitude?The term Longitude has been refered as the horizontal lines that are the measurement east or west of the prime meridian. Longitude are the imaginary lines that divide the Earth. Longitudes are also called the meridians, which run from north to south pole to pole but they measure the distance east or west.
The hypothesis that the species diversity is greater at lower latitudes than higher latitudes because low-latitude habitats are older would be supported if speciation rates were: the same at high and low latitudes.
Species diversity can be defined as the number of species, present in an area or the ecosystem. More are the number of species, more diverse is the area is. The richness and functionality of an ecosystem is estimated through its diversity.
Therefore,longitudes are the horizontal lines which divide the Earth.

Focusing on body mechanics is important for athletes as it improves their effectiveness, and technique, and reduces the risk of injury is a true statement.
1. According to Newton’s second law of physics, if there are two objects of equal size but object A is heavier than object B, then the statement that is true is option C: Object A will require more force to be set in motion but will travel faster than object B. Newton's second law of motion states that acceleration is directly proportional to the force applied and inversely proportional to the object's mass. Since both objects are of equal size but object A is heavier, it will require more force to be set in motion. However, once in motion, it will have more inertia and travel faster than object B.2. The statement "For athletes, a focus on body mechanics improves the effectiveness of their efforts" is True. Body mechanics refers to the way in which the body moves and maintains balance while performing a physical task. Athletes need to have proper body mechanics to achieve maximum efficiency and reduce the risk of injury. By focusing on their body mechanics, athletes can improve their technique, reduce unnecessary movements, and improve their overall performance. Good body mechanics can also help to prevent injury and reduce wear and tear on the body. Therefore, a focus on body mechanics is essential for athletes to maximize their performance while minimizing their risk of injury. In summary, Newton's second law states that a heavier object requires more force to be set in motion, while a focus on body mechanics can improve the effectiveness of athletes' efforts.For more questions on Newton's second law

Think about an object to which you have applied a force to change its velocity. Now think about an object that has a smaller or larger mass than that object. Answer the following prompt:
Describe a situation in which the force required to change the velocity of an object changes based on the mass of the object.
Describe a simple experiment you could perform that would generate data to provide evidence that the change in an object’s motion depends on either the forces on the object or the mass of the object.
Answer:
Explanation:
F=ma

Which does not take the direction of the motion into account?
Displacement
Distance
velocity
Velocity and displacement take direction of motion into account while distance does not take direction of motion into account.
Vector quantities take into account both magnitude and direction of motion while scalar quantities only take the magnitude of motion into account. In describing the motion of an object, we use terms such as; velocity, distance, displacement etc.
Looking at the options provided in the question, displacement and velocity are vectors hence they take the direction of motion into account. Distance is a scalar quantity hence it does not take direction of motion into account.

Explanation:
The forces act on skateboard when we push it are , external force of 500N and friction force because of the surface.
What is the Newton's First law of motion?The stationary object will remain stationary or the subject in the motion will keep its motion until or unless the external force is not applied .
What will happen when we apply 500 N external force to the skateboard?We know the only force which is going to oppose the applied 500N force is the friction force due to surface.First as we will apply the external force the skateboard and the box will start gaining the velocity and the accelerationAfter some time because of the friction force the skateboard and the box will start losing its velocity because of the friction force and the combined mass they are having and at the end it will stop moving forward. it is also depends on their mass also.If we put different types of objects on the skateboard then the time period of lost of velocity will be different .If we put object having more mass then the combined system (skateboard + object ) will start losing its velocity quickly . and visa versa for the object having less mass.So, by the Newton's first law of motion we can understand this concept.
