A boy is flying a kite. His kite string is extended 50 meters long. The boy is 1.7 meters tall, and the angle of elevation of the kite to the boy's hands is 12°. How high is the kite flying above the ground?

Answers

Answer:

12.1 meters

Explanation:

Please check the attached image for a diagram of the question

We are given the value of the hypotenuse and we are to determine the value of the opposite side. Thus, we would use sin

Sin = opposite / hypotenuse

sin 12 = opposite / 50

0.2079 =  opposite / 50

opposite =  0.2079 x 50 = 10.4 meters

height of the kite above the ground = 10.4 + 1.7 = 12.1 meters

Radiation is a concern with travelling away from the Earth.
What kind of radiation is concerning to astronauts in this journey? ( the trip to Mars)

Answers

Answer:

ionizing radiation

Explanation:

the radiation from the sun is ionizing.

Mark Brainliest please

Answer:

Ionising radiation

Space radiation is made up of three kinds of radiation: particles trapped in the Earth’s magnetic field; particles shot into space during solar flares (solar particle events); and galactic cosmic rays, which are high-energy protons and heavy ions from outside our solar system. All of these kinds

It comes

Space radiation can cause radiation sickness and other health problems. These effects are classified as either acute, which have immediate impacts on humans, or chronic, which affect humans over longer periods of time.

Radiation on Mars

Radiation exposure on the surface is 30 µSv per hour during solar minimum; during solar maximum, dosage equivalent of this exposure is reduced by the factor two (2). If the settlers spend on average three hours every three days outside the habitat, their individual exposure adds up to 11 mSv per year.

Space radiation is made up of three kinds of radiation: particles trapped in the Earth’s magnetic field; particles shot into space during solar flares (solar particle events); and galactic cosmic rays, which are high-energy protons and heavy ions from outside our solar system. All of these kinds of space radiation represent ionizing radiation.

Why is Ionizing Radiation More Dangerous than Non-Ionizing Radiation?
While non-ionizing radiation is damaging, it can easily be shielded out of an environment as is done for UV radiation. Ionizing radiation, however, is much more difficult to avoid. Ionizing radiation has the ability to move through substances and alter them as it passes through. When this happens, it ionizes the atoms (knocks electrons out of them) in the surrounding material with which it interacts.

Ionizing radiation is like an atomic-scale cannonball that blasts through material, leaving significant damage behind. More damage can also be created by secondary particles that are propelled into motion by the primary radiation particle.

The particles associated with ionizing radiation in space are categorized into three main groups relating to the source of the radiation: galactic cosmic rays, solar flare particles, and radiation belt particles (Van Allen Belts) trapped in space around the Earth.

Differentiate between renewable and non-renewable resources. Give examples of
both. What are the dangers in depending too much on non-renewable resources?

Answers

Renewable resources can be replaced by natural processes as quickly as humans use them. Examples include sunlight and wind.

Nonrenewable resources exist in fixed amounts. They can be used up. Examples include fossil fuels such as coal.

Greenhouse gas emissions

Perhaps the most well-known impact of using non-renewable energy sources is the emission of greenhouse gases, in particular carbon dioxide and methane, which contribute to climate change [1]. Different types of non-renewable energy fuels emit different levels of greenhouse gases.

Describe how the rotation of Earth around its own axis and its revolution around the sun affect sunrise and sunset. Explain why will this be different from outer space.

Answers

Answer:

since earth rotates on a tilted axis we experience night and day, and also different seasons. while being tilted on our axis we can experience longer days and shorter night when pointing towards the sun (summer), and shorter days and longer night pointing away from the sun (winter). you would experience a difference in space because you wouldn't be rotating on a axis any more. you would experience the same night and day patterns every day.

B. Executive leaders would have to be chosen from the legislative
branch.
C. An elite group would have to take control of the government.
D. An assembly of all citizens would have to take control from an

Answers

Answer: B. Executive leaders would have to be chosen from the legislative branch.

Explanation:

A parliamentary democracy is one where the executive government is controlled by the party that has the largest representation in the nation's legislative branch, the Parliament.

To be a parliamentary democracy therefore, an executive leader would have to be chosen from the legislature by the members of the party in the majority. This ensures that the legislature and the executive work closer together. Countries like Britain and Israel are parliamentary democracies.
