A diverging lens has a focal length that has a magnitude of 37.0 cm. An object is placed 20.0 cm in front of this lens. Calculate the magnification.

Iwould think it is temperature, silica, oxides (gases)

The  moon has  insufficient gravity to retain an  atmosphere. we conclude that the moon has no atmosphere  because its gravitational field is too weak to  have  retained any  atmosphere  that it had over times comparable to the age of the solar system.

I’m not sure about this question
