3 0
Connection to Big Idea about energy: Gravity creates gravitational potential energy. Gravitational energy relies on the masses of two bodies and their distance.

Connection to Big Idea about the universe: Gravitational force is exerted by all objects with mass throughout the Universe. It is what keeps the Earth and the planets in orbit around the Sun, and our Solar System in orbit around the centre of the Milky Way. Gravity is one of the forces involved in the birth of stars, their evolution and finally their death.

Connection to Big Idea about Earth: The gravitational force is responsible for many physical properties of Earth and consequently it affects the existence and the properties of living creatures on it. For instance, the existence, the chemical composition and the structure of Earth’s atmosphere was determined by Earth’s gravitational force.

Describe how computer climate models help scientists understand possible future climate changes. How reliable are these computer
ExtremeBDS [4]
To predict future climate, scientists use computer programs called climate models to understand how our planet is changing. Climate models work like a laboratory in a computer. They allow scientists to study how different factors interact to influence a region's climate.


Now a new evaluation of global climate models used to project Earth's future global average surface temperatures over the past half-century answers that question: most of the models have been quite accurate.

a machine is used to lift crates of oranges has an efficiency of 65%. if the machine provides 1300 newtons through a distance of
mylen [45]

Given data

  efficiency (η) = 65 %

                        = 0.65

  Machine provides (Work done by the machine) = 1300 × 50

                                                                                 = 65000 J

  efficiency (η) = work done by the machine ÷ work supplied to the machine

               0.65 =  65000 ÷ Input work

              Input work = 100000 J

                                = 100 KJ

Satuarated solution changes into unsatuarated by heating give reason​
Crazy boy [7]

Answer:

Due to application of heat on a saturated solution, the interparticle space increases due to increase in the kinetic energy of the particles which allows more solutes to dissolve in the solution thereby making it unsaturated.
