Why are asteroids and comets important to our understanding of solar system history?

Physics
1 answer:
Alecsey [184]3 years ago
8 0

Answer:

Explained

Explanation:

It is widely believed among the space scientist that Asteroids and comets are the remains of the material that has formed our solar system. By studying Asteroids and comets can get information pre era of our solar system, because the asteroids came being at the start of the solar system. The chemical composition, the size and the process of formation of proto stellar nebula. The impact of collision of asteroid on Earth lead to the extinction of Dinosaurs. Previously it was believed that water come on Earth because of comets, but later proved that water come into being on Earth because of Asteroids.

The metric unit of force is the
grandymaker [24]

The unit of force is the 'Newton'.

1 newton is the force that accelerates 1 kilogram of mass
at the rate of 1 meter per second-squared.

                   1 N  =  1 kg-m/s²

-- A force of 1 pound is about  4.448 newtons.

-- A force of 1 newton is about  3.6 ounces.

A 10 kg blue cart moving to the right at 25 m/s collides with a 17 kg red cart moving in the opposite direction at 16 m/s. If, a
scoray [572]

Answer:

24.8m/s

Explanation:

Given data

m1= 10kg

u1=25m/s

m2=17kg

u2=16m/s

v1=10m/s

v2=??

Applying the conservation of linear momentum

m1u1+m2u2=m1v1+m2v2

substitute

10*25+17*16=10*10+17*v2

250+272=100+17v2

522=100+17v2

522-100=17v2

422=17v2

Divide both sides by 17

v2= 422/17

v2= 24.8 m/s

Hence the velocity of the red cart is 24.8m/s in the opposite direction of the blue cart

An example of kinetic energy is a _____.
zhenek [66]

Answer:

An example of kinetic energy is a <u><em>car coming to a stop</em></u>

Explanation:

Kinetic energy is the energy that a body or system possesses due to its movement. In physics this energy is defined as the amount of work necessary to accelerate a body of a certain mass and in rest position, until reaching a certain speed. This energy obtained will remain unchanged as long as this body does not vary its speed. That is, kinetic energy measures how many changes an object that is moving can cause.

<u><em>An example of kinetic energy is a car coming to a stop</em></u>. If the car is moving and comes to a stop, there is a change in speed, therefore in movement, eventually producing a change in kinetic energy. This energy depends on the mass of the body, in this case the car, and the speed.  As the speed decreases, the kinetic energy will decrease.
