What are newtons laws?

Answers

Explanation:

Newton's 1st law: An object in motion stays in motion, and an object at rest stays at rest, until acted upon by an unbalanced force.

Newton's 2nd law: Force equals mass times acceleration.

Newton's 3rd law: For every action, there is an opposite and equal reaction.

What is one of Kepler's laws of planetary motion?

Answers

The Kepler laws of planetary motion are:

1) The planets revolve around the Sun following elliptical orbits, in which the Sun occupies one of the two focii

2) A line segment connecting the Sun with the center of each planet sweeps out equal areas in equal intervals of time --> this means that the speed of the planet changes according to its distance from the Sun: the closer to the Sun, the faster the planet

3) The square of the orbital period of the planets is proportional to the cube of the semi-major axis of the orbit. In formula

and the constant in the equation has the same value for every planet orbiting around the Sun.

Which of the following is considered to be a vector?

A. Temperature
B. Mass
C. Velocity
D. Time

Answers

Answer:

10. B. 30 kg.m/s

16. B. Elastic collision

20. Velocity

Explanation:

10. Momentum is simply the product of mass and velocity of an object. So it can be soved with the equation:

p = mv

Where:

p = momentum (kg.m/s)

m = mass (kg)

v = velocity (m/s)

Your problem gives you the following:

m = 15 kg

v = 2 m/s

p =?

So just fill in what you know:

p = mv

(Video) Balloons in the Air: Understanding weather and climate

p = (15kg)(2m/s) = 30 kg.m/s

16. Elastic collision occurs when two objects collide and no loss in energy occurs after collision. Supposing that the balls are very bouncy, let's say they bumped into each other and they bounce-off of each other. If there is no loss in speed on both ends, that means that this is an elastic collision.

20. To differentiate vector and scalar quantity, just remember that vectors have direction. Both quanitites show magnitude, but vector quantities indicate the direction the magnitude is going. Among all the choices, it is only velocity that is considered as a VECTOR quantity.

FAQs

What does a weather balloon do? ›

Weather balloons are the primary source of data above the ground. They provide valuable input for computer forecast models, local data for meteorologists to make forecasts and predict storms, and data for research.

What weather data do they get from a weather balloon? ›

These observations include vertical profiles of temperature, humidity, wind speed and direction, atmospheric pressure, and geopotential height.

What is the purpose of launching a weather balloon quizlet? ›

A weather balloon is launched into the atmosphere by meteorologists. When the balloon reaches an altitude where it is neutrally buoyant, it transmits information about weather conditions to monitoring stations on the ground.

How can a weather balloon be used to predict future weather conditions in a location? ›

Thanks to weather balloons, officials can prepare for a weather disaster hours before it strikes. Weather balloons collect and send the following critical data back to the ground: wind speed, wind direction, air pressure, air temperature, relative humidity, cloud type, and GPS location.

What happens when weather balloons rise? ›

As the balloon rises, the gas inside the balloon expands because the atmospheric pressure surrounding the balloon drops. The atmosphere is 100 to 200 times less dense at the float altitudes than on the ground.

How accurate is a weather balloon? ›

On average, the balloons make it around 20 miles high before they burst. Airplanes only fly between 6 and 7 miles high. According to NWS meteorologist Francis Kredensor, the data the balloons send back is some of the most accurate in the world of weather.

What sensors are on a weather balloon? ›

People use a radiosonde, hanging on a string underneath the balloon, to measure atmospheric data for making an accurate weather forecast. The radiosonde carries sensors to collect observation including the gathering of air pressure, temperature, and relative humidity.

What are the advantages of using weather balloon rather than an aircraft? ›

Fewer errors as the aircraft movement/heat could affect the data from the sensors. If the air balloon is checking wind speed it is floating/constant speed therefore more accurate. Safer, in the event of severe/extreme weather conditions due to the weather balloon not being manned.

What is the reason why a balloon will pop in the atmosphere? ›

Pressure decreases as we go up in the atmosphere so when the helium balloon rises up the pressure inside the balloon becomes more than the pressure outside and so the balloon first expands and then finally bursts.

What was the purpose of the hot air balloon when it was invented? ›

In 1874 Jean Pierre Blanchard successfully flew across the English channel using hydrogen. Ballooning made major advances through scientists and because of war. Gas balloons were used by the french as lookouts and were often called the spies of the sky.

What is used to predict weather changes? ›

Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists.

What are the things used to predict the weather? ›

Land-based weather stations around the world and automatic stations observe the atmospheric pressure, wind direction and speed, temperature of the air, humidity, clouds, precipitation and visibility using standard weather instruments such as the barometer, wind vane, anemometer, thermometer, psychrometer or hygrometer ...

What factors determine the altitude at which a weather balloon will burst? ›

The atmospheric temperature, pressure, air density, size of balloon, amount of fill, payload mass and many other factors contribute to what altitude a balloon can reach.

What is the explanation of a balloon? ›

A balloon can be defined as an inflatable flexible bag filled with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. Modern balloons are made from materials such as rubber, latex, polychloroprene, metalized plastic or a nylon fabric. Long before there was something as stretchy as rubber, balloons existed.

What is the balloon experiment? ›

SCIENCE: When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon. The more gas that is created, the larger the balloon will inflate.

He told that the debris recovered was not a weather balloon, and claimed it did not come from this planet. This example is from Wikipedia and may be reused under a CC BY-SA license. She claimed the pieces looked like a weather balloon.

What happens to weather balloons when they come down? ›

Eventually, the weather balloon will pop and the parachute, string, and radiosonde land back on the Earth surface. All items used in a launch are biodegradable except for the radiosonde, which if found, can be returned to the National Weather Service.

How far can a balloon travel? ›

The balloon can only rise up until the atmosphere surrounding it has the same weight as the helium in the balloon. This happens at about a height of 20 miles (32 kilometers) above Earth's surface. So, this is as far as a helium balloon can rise.

Why do weather balloons get bigger? ›

Answer: The volume of the gas is inversely proportional to the pressure at a given temperature according to Boyle's law. As the weather balloon ascends, the pressure tends to decrease. As a result, the volume of the gas inside the balloon or the size of the balloon is likely to increase.

Can anyone fly a weather balloon? ›

Do weather balloons hit planes? ›

A: Yes, I have seen several weather balloons while in flight. There have been cases where weather balloons have been struck by airplanes. Usually there is no damage to the aircraft, but occasionally to the weather instruments. It's a rare occurrence.

Who invented the weather balloon? ›

What are balloons used for remote sensing observation of? ›

Balloons are used for remote sensing observation (aerial photography) and nature conservation studies. The first aerial images were acquired with a camera carried aloft by a balloon in 1859. Balloon floats at a constant height of about 30 km.

What is a fun fact about weather balloon? ›

Weather Balloon Facts
  • The Upper Air Observing Program of NOAA started back in the 1930s.
  • Balloons are either filled with helium or hydrogen, both of which are lighter than air.
  • The radiosonde is exposed to temperatures as low as -130˚F during its flight.
  • Balloon expands as it rises due to the lack of pressure.

Can you pop a weather balloon? ›

Not your average party balloon

As the balloon soars into the atmosphere, they expand to the size of a two-story house. Eventually, the pressure inside the balloon becomes too great for the balloon, and it pops.

What color are weather balloons? ›

Three different colors provide easier sighting under varying weather conditions. The natural color has the greatest visibility on clear days; red is easiest to see in scattered clouds; and black is best for overcast conditions.

What are the advantages of ballooning? ›
