Answer:

Meteor

Explanation:

Meteoroids are small fragments of rock from the debris of an asteroid that is outside of the Earth's atmosphere. When one of this fragments of rock cross in the orbital Earth's path, it will start to enter the Earth's atmosphere and it will ignite as a consequence of the friction between the rock and the atmosphere, and due to its velocity it will be seen as a streak of light of different colors on the celestial sphere depending on the chemical composition in that particular place of the atmosphere. In that scenario, a Meteor is gotten.        

 

On the other hand, a Meteorite is gotten if that Meteor doesn't completely disintegrate in the atmosphere and is capable to reach the ground.

Alex_Xolod [135]

Answer:

\theta_2 = 15.8degree

Explanation:

given data:

\theta_1 = 28.7 degree

accoding to the snell's law

n_1*sin\theta_1=n_2*sin\theta_2

where n1 is refracting index of air = 1

n2 is refracting index of glass = 1.55

putting all value to get angle mad by incident ray with normal

\theta_2 = \frac{1*sin28.7^{o}}{1.55}

\theta_2 = 15.8degree

A 620 kg moose is standing in the middle of a train track. A 10,000 kg train moving at 10 m/s is unable to stop and the moose en
ddd [48]

Answer:

This is an example of Inelastic colission

Explanation:

Step one:

given:

mass of moose m1 = 620 kg

mass of train m2= 10,000kg

Initial velocity of moose  u1= 0 m/s

Initial velocity of train v1 = 10m/s

combined velocity of the system is given as v

Applying the conservation of momentum equation we have

m1u1+ m2u1= (m1+m2)V

substitutting we have

620*0+10000*10= (620+10000)V

100000= 10620V

divide both sides by 10620

V = 100000/10620

V=9.41m/s

The velocity of the moose after impact is 9.41m/s
