A1.30 kg skateboard is coasting along the pavement at a speed of 6.64 m/s when a 0.680 kg cat drops from a tree vertically downward onto the skateboard. what is the speed of the skateboard-cat combination?

Explanation:

The principle of conservation of linear momentum states that if the sum of forces acting on a system is zero, its linear momentum remains constant over time. So, in this case we have:

The cat drops downward, so their initial speed horizontally is zero(). The skateboard and the cat collide and stick together, so their final speeds are the same():

explanation:

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the
