A 7.77 kg mass is moving due west at 7.77 m/s. A second mass of 8.88 kg is moving due south at 8.88 m/s. What is the magnitude o

masya89 [10]

Answer:

8.362m/s

Explanation:

Given data

Mass m1= 7.77kg

Velocity v1= 7.77m/s

Mass m2= 8.88kg

Velocity v2= 8.88m/s

Apply the law of conservation of momentum for inelastic collision we have

m1v1+m2v2= (m+m2)V

7.77*7.77+ 8.88*8.88= (7.77+8.88)V

60.3729+78.8544= 16.65V

139.2273= 16.65V

Divide both sides by 16.65

V= 139.2273/16.65

V= 8.362m/s

Hence the final velocity is 8.362m/s

The following figures show four stages that occur during the formation of a one-solar-mass star. Rank these stages based on thei

Stolb23 [73]

Answer:

The four stages that occur during the formation of a one-solar-mass star are as follows:

Explanation:

The formation of the Red dwarf which is also one of the celestial entities inside the galaxies as, the formation of the more gradual body of the mixture of different gasses having a imaginable low temperature. As this whole process leads to the formation of the main sequence star.
When the different masses of the mixtures of the gases combines to form a very celestial body then it leads to the composition of each component inside the celestial body to acquire a very flattened form of structure leading to the flattened disk with radiation properties. As the Protostar with jets is formed which means that still the star is in the process of collecting the right amount of materials for its bodily development.
The star formation does take a very swift form of development when all the required number of factors are there to satisfy the formation of the star, as these star nurseries are able to collect the right level or optimum amount of energy for its formation.As, these contracting cloud trapping the infrared light or radiation inside it.
Now, after the different conditions and terms for the formation of the star are satisfied then the mass or shape which the different components of the star body takes place is the molecular cloud fragment.

People living at Earth’s equator are traveling at a constant speed of about 1,670 km/h as Earth spins on its axis. What are thes

Vlada [557]

The people living around the equator experience acceleration. Acceleration is the change in speed or/and direction. When on a rotating body, the speed does not change it is only the direction that changes as it rotates.When on a rotating body you do not have to change speed but only direction. In a normal situation when you are traveling on a circle you will never have a straight line.
