Answer:
Explanation:
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.
Answer:
The mass of the skateboard is 1.25 kg.
Explanation:
We have,
Mass of dog, m = 5 kg
Initial speed of dog, u = 2.5 m/s
Initial speed of skateboard, u' = 0 (at rest)
The dog jumps onto the skateboard and both the dog and skateboard move with a speed of 2.00 m/s. It is the common speed of the dog +skateboard, V = 2 m/s. We need to find the mass of the skateboard. Using conservation of momentum as :

m' is mass of skateboard

So, the mass of the skateboard is 1.25 kg.

Therefore, the ball has a velocity of 4m/s.
Answer:
The only parameter that changes is mass m
It is only necessary to calculate the ratio Eh/Ee

The kinetic energy of the heavy paricle is three times the kinetic energy of an electron
