Hello!
The kind of gas cloud that is most likely to give birth to stars is a cold, dense gas cloud.
Stars are formed in giant molecular clouds, called "star nurseries". These are regions with molecular Hydrogen, Helium, and little amounts of other elements. These are cold and dense regions, and the gas cloud collapses, forming a protostar. The protostar gradually heats, powering nuclear reactions in its center, which increases the temperature even more and giving birth to a star.
Have a nice day!
First, let's calculate the total mechanical energy when the block is at rest and the spring is compressed 5 cm:
Now, let's use this total energy to calculate the velocity when the spring is compressed by 2.5 cm:
Therefore the speed is 1.026 m/s.
Explanation:
Most waves appear complex because they result from two or more simple waves that combine as they come together at the same place at the same time—a phenomenon called superposition. Waves superimpose by adding their disturbances; each disturbance corresponds to a force, and all the forces add
