5. They’re used to find the temperature of stars. - Visible

6. They have energy. - Both

Explanation:

The magnetic spectrum consists invisible and visible part of the spectrum. The invisible part consists of radio waves. These are waves used for radios, tvs, and cellphone communications. They satisfy all the properties of transverse waves.

The visible part comes from light. This is the part that is visible to the naked eye. Examples are ultraviolet rays, the sun, neon lights etc. To determine how hot something is, the visible portion is used. The brighter the object, the hotter it is.  Thus, the brightness of the stars can be determined by the color of the light emitted. The visible rays satisfy all the properties of transverse waves. However, light is considered a dual nature - it has wave and electron-like properties.

Answers

A sudden drop in the temperature is a sign that the weather may change for the worse for the temperature balance become vulnerable, it may cause strong storm. This change is due to the change in air, water and the resulting pressure gradients that stimulate the movement of air masses. 

A sudden drop in the temperature is a sign that the weather may change for the worse. Long-term changes in temperature are referred to as weather patterns.

What is a weather change?

Long-term changes in temperature and weather patterns are referred to as weather changes. These movements might be due to natural causes, such as oscillations in the solar cycle.

An oncoming cold front is signaled by a reduction in air pressure and temperature. Severe weather, such as heavy rain, hail, destructive wind gusts, lightning, and even tornadoes, are caused by these fronts.

A sharp decrease in temperature indicates that the weather is about to shift for the worse, putting the temperature balance at risk and may be resulting in a violent storm.

This shift is caused by changes in the air, water, and the pressure gradients that follow, which encourage the movement of air masses.

Hence the sudden drop in the temperature is a sign that the weather may change for the worse.

1) With your pneumatic system, how do you think your results would have been affected if there had been a leak in the tubing?
2) Given your observations for this investigation, would you rather ha a hydraulic braking system Or a pneumatic braking system in your car. Explain.

Answers

a leak means air escapes, so the car wouldn't brake.  
Final answer:

A leak in the tubing of a pneumatic system would decrease its efficiency. A hydraulic braking system would be preferred for a car.

Explanation:

If there had been a leak in the tubing of a pneumatic system, the results would have been affected. A pneumatic system uses compressed air to transmit force, and if there is a leak, a decrease in pressure would occur. This would result in a decrease in the efficiency of the system, as the force applied may not be transmitted properly.

Based on the observations and the information provided, it is likely that a hydraulic braking system would be preferred for a car. A hydraulic system, like the one used in hydraulic brakes, utilizes an incompressible liquid to transmit force. This ensures that the force is transmitted efficiently without any loss due to compression or leaks.

Explain the difference between strength,muscular endurance and power

Answers

muscular endurance is the ability of a muscle or muscle group to exert force to overcome a resistance. Strength is the amount of work you can do with your muscles at one time. Power is when you use your muscles to perform high intensity movements in short bursts.

The difference between strength, muscular endurance, and power include:

Strength simply means the ability of a muscle to be able to generate force against resistance. On the other hand, power simply means a large amount of force that can be generated quickly. Muscular endurance simply means the ability of muscles to be able to exert force against a particular thing for a period of time.

Strength has to do with one repetition while power has to do with several repetitions. Muscular endurance involves constant repetition.

It should be noted that power, strength, and muscular endurance are forms of muscular ability.

Final answer:

In physics, another term for the position of an object is 'displacement'. Displacement refers to the change in position of an object in relation to a reference frame, and specifies the direction of movement.

Explanation:

In the field of physics, another term for the position of an object is displacement. Displacement refers to the change in position of an object in relation to a reference frame. For instance, if an object moves to the right relative to a whiteboard, its position, or displacement, changes.

To illustrate, imagine an airplane in motion. To describe the position of a passenger in the airplane, you would use the airplane, not Earth, as the reference frame. Therefore, the passenger's displacement could be toward the rear or front of the airplane.

The key point to remember is that displacement not only refers to the change in position, but also specifies the direction of the movement. It's therefore considered a vector, and can be either positive or negative, depending on the chosen positive direction.

In order to get the bike to move and stay moving, what friction must be overcome

Answers

Friction is the resistance offered against the motion of one surface over the other. This is because, at the microscopic level, each surface has hills and valleys i.e. the surfaces are not completely smooth and hence the roughness of one surface locks over the other and restricts its motion. There are two kinds of friction: static friction and kinetic friction. When the object is at rest, static friction acts. While the object is in motion, kinetic friction acts. Static friction is greater than the kinetic friction because a larger force is required to change the state of rest to motion. You must have experienced that if you do not accelerate the bike while its in motion, it would slow down and eventually stop. In order to get the bike moving, initially static friction must be overcome and thereafter, kinetic friction to make it stay in motion.

What was the average speed of the hummingbird flying from one feeder to the other?

Answers

Answser: 8 m/s


Explanation:


Sally performed an experiment, in which she handled two variables:


distance between the feeders, andtime to fly from one feeder to next.

The distance is fixed, so she only measured it one time and it was 24m.


She timed 10 trials and calculated the average time of 3 seconds. So, you will use this time fo calculate the average speed of the hummingbird flying from one feeder to the other, using the formula:


speed = distance / timespeed = 24 m / 3 s = 8 m/s.

Hence, the result is 8 m/s.

problems with solar energy include

Answers

the inability of current technology to capture large amounts of the Sun's energy the inability of current technology to store captured solar energy inconsistencies in the availability of the resource lack of demand for solar energy.

Final answer:

The problems with solar energy include its intermittency and the high upfront cost of battery storage systems. The production of photovoltaic cells generates hazardous waste, and deployment of large-scale solar systems can harm undeveloped habitats. Also, solar energy cannot directly power all sectors like cars and airplanes due to its diffuse nature.

Explanation:

There are a number of challenges and problems associated with the use of solar energy. Some primary issues include its intermittency, as solar energy capture is not constant, and can be particularly low during the nighttime or in seasons with less sunshine. This inconsistency can be offset by battery storage, but such storage solutions add substantial cost, need regular maintenance, and require the environmentally unfriendly process of battery replacement.

Another concern is the environmental impact of photovoltaic (PV) cells, the main technology for generating solar energy. The process of manufacturing PV cells requires the use of chemicals and solvents, generating some hazardous waste. Besides, the deployment of large-scale solar arrays in undeveloped areas or fragile ecosystems like deserts can cause habitat destruction. Solar thermal systems, another form of solar energy, also pose problems as they use potentially hazardous fluids for heat transfer and need significant amounts of water for cleaning and cooling.

Finally, solar energy can't directly power some sectors and applications such as cars and airplanes due to its diffuse nature, making it not entirely substitutable with other energy sources. While the sun provides an abundant source of energy, transitioning to a solar-powered society poses significant challenges.

n the picture of a planet in orbit around its star area a is double that of area b. What is true of the time the planet takes to travel A1A2 as compared to B1B2

Answers

The Kepler's laws predict the planetary motion, so there are three laws for this, namely:

1. The orbit of a planet is an ellipse with the Sun (the sun is a star!) at one of the two focus.

2. A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.

3. The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.

So, let's use second law. The Sun sweeps out equal areas during equal intervals of time means that if A = B, the time the planet takes to travel A1A2 is equal to the time the planet takes to travel B1B2, but given that A = 2B, then takes twice the time to travel A1A2 compared to B1B2.

Final answer:

The bird population often benefits from the removal of predators, as seen with the decrease in bird species due to introduced predators like the brown tree snake in Guam. However, ecosystem dynamics can be complex, and the overall impact of predator elimination can vary.

Explanation:

Based on the information provided, the bird population does seem to benefit from the elimination of predators such as rattlesnakes. For instance, in habitats where predatory snakes were introduced, such as the brown tree snake in Guam, there were significant declines in native bird populations. This indicates that predators can have a drastic effect on bird populations. Without the presence of such predators, bird species that were previously preyed upon could potentially recover in numbers.

The example given of the Yellow-billed Cuckoo shows that bird nesting preferences, and indirectly population health, can be influenced by habitat quality. A healthier habitat without the stress of predation can lead to increased bird populations. However, each ecosystem is unique, and the role of predators can be complex. In some cases, predators can control populations of species that might otherwise explode in numbers and disrupt the balance of the ecosystem, so the benefit to bird populations upon the removal of a predator can vary.

In summary, while the elimination of a predatory species like rattlesnakes can lead to the recovery of certain bird populations, the overall effect in an ecosystem may be complex and is dependent on numerous factors including habitat health, availability of food sources, and absence of other predators or stressors.
