A 4.00 kg object is moving at 5.00 m/s NORTH. It strikes a 6.00 kg object that is moving WEST at 2.00 m/s. The objects have a completely inelastic (stick together) collision. The velocity of the 4.00 kg object after the collision is

2.33 m/s

Explanation:

Given

4 kg mass is moving towards North at

and 6 kg mass is moving towards the west at

They collide inelastically i.e. stick together

Conserving momentum in the horizontal direction(west)

Conserving momentum in the vertical direction(North)

Net velocity is the vector sum of two velocities whose magnitude is given by

The velocity of 4 kg mass will be the same as the combined mass because both the mass are moving together.

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

happy to

pls mark as brainliest.

c)as speed changes, wavelength and frequency change.

everything changes!
