Answer:

collapse, condensation and accretion

Explanation:

According to the nebula hypothesis all the bodies in our solar system began as a giant cloud of molecular gas and dust, something happened about 4.57 billion years ago which caused the cloud to collapse (collapse).  

  After the collapse pockets of dust and gas came together to form denser regions (condensation). this denser regions pulled in more matter and conservation of momentum caused it to begin rotating and then heating up due to increasing pressure. Most of the material ended up in a ball around the center which and the rest of the matter flatten out into disk (protoplanetary disc) around it (accretion).

A 3.9 kg ball traveling towards a soccer player at a velocity of -3.5 m/s rebounds off the soccer player's foot at a velocity of
Tresset [83]

Answer: 2.92 s

Explanation:

Given

Mass of ball is m=3.9\ kg

The initial velocity of the ball is u=-3.5\ m/s

Velocity after the rebound is v=15.9\ m/s

Force during the contact is F=25.9\ N

We know, change in momentum is Impulse

\Rightarrow F\cdot \Delta t=m(\Delta v)

\Rightarrow 25.9\cdot \Delta t=3.9(15.9-(-3.5))\\\\\Rightarrow \Delta t=\dfrac{3.9\times 19.4}{25.9}=2.92\ s

Thus, the force is applied for 2.92 s

beks73 [17]

Answer:

Yes, it is reckless. This is because it is the responsibility of the pilot to make sure that the direction of the propeller blast is away from people or other aircraft and in a safe direction.

Explanation:

Yes, it is reckless to let the propeller blast face people and other aircraft. This is because it is the responsibility of the pilot to make sure that the direction of the propeller blast is away from people or other aircraft and in a safe direction. People and other aircraft can be injured by the debris and the rocks that are scattered by the engine of the aircraft.
