Answer:
In symbols, the magnitude of the attractive force F is equal to G (the gravitational constant, a number the size of which depends on the system of units used and which is a universal constant) multiplied by the product of the masses (m1 and m2) and divided by the square
Answer:
Explanation:
The speed of light in a vacuum is approximately 3×10⁸ m/s.
In water with η=1.33:
v = (3×10⁸ m/s) / 1.33
v = 2.26×10⁸ m/s
In glass with η=1.50:
v = (3×10⁸ m/s) / 1.50
v = 2.00×10⁸ m/s
Answer:A satellite maintains its orbit by balancing two factors its velocity the speed it takes to travel in a straight line and the gravitational pull that Earth has on it. A satellite orbiting closer to the Earth requires more velocity to resist the stronger gravitational pull.

Answer:
b a model of water temperatures in the oceans
Explanation:
A conceptual model is a means of representing abstract theories, with the aim of helping the audience form mental pictures about the subject being discussed. Most of these models utilize diagrams to help form a better understanding of the subject.
In geothermal explorations, water temperatures can be represented using plane or cross sectional views to demonstrate the varying temperatures of water. This is a useful guidde in the exploration proceess and helps any who read the illustrations to form a better understanding of the process and conditions.
in magnets the polarities are exact opposites and in nonmagnetic object the are not so they don't have a magnetic attraction
