Answer:
Explained
Explanation:
It is widely believed among the space scientist that Asteroids and comets are the remains of the material that has formed our solar system. By studying Asteroids and comets can get information pre era of our solar system, because the asteroids came being at the start of the solar system. The chemical composition, the size and the process of formation of proto stellar nebula. The impact of collision of asteroid on Earth lead to the extinction of Dinosaurs. Previously it was believed that water come on Earth because of comets, but later proved that water come into being on Earth because of Asteroids. 
 
        
             
        
        
        
Answer:
i think your answer is this: the objects have no interactive with each other.

Answer:
Explanation:
His Kinetic energy = 1/2 m v^2
v = 5 m/s
m = 75 kg
Ke = 1/2 75 * 5^2
Ke = 937.5 Joules
This will be converted to PE when he reaches the maximum height he reaches. In other words KE = PE
PE = m * g * h
m = 75
g = 9.81
h = ?
PE = 937.5
937.5 = 75 * 9.81 * h
937.5 = 735.75 * h 
937.5/735.75 = h
h= 1.27 meters
 
        
             
        
        
        
Explanation:
A magnetic field can be created by running electricity through a wire. All magnetic fields are created by moving charged particles. Even the magnet on your fridge is magnetic because it contains electrons that are constantly moving around inside
