Answer:
What is velocity?
v = d/t = distance / time you need to know this formula !
= 10 m/ 4 s = 2.5 m/s
Explanation:
Answer:
A. acceleration
Explanation:
Acceleration is the increase of motion, it is the rate at which an object changes its velocity.
Well, one example is that the weight of the rider puts downward force on the motorcycle, which is absorbed by the suspension or shocks or something.
Answer:
Comets
Explanation:
Comets are planetary celestial bodies consisting of ice and dust, sometimes rocky particles formed in the region of the solar system. Long-period comets propagate towards the Sun by gravitational perturbations caused by passing stars. Some comets usually hyberbolic comets, move through the inner Solar System prior to entering the interstellar region. Short period comet lies beyond the orbit of the Neptune.
The Jovian planets include Jupiter, Saturn, Uranus, and Neptune.
Therefore, leftovers of comets (planetesimal bodies) formed in the region of the solar system that are now occupied by the Jovian planets is due to the dusty particles associated with the comets.
Explanation:
The tangential speed of Andrea is given by :
![v=r\omega](https://tex.z-dn.net/?f=v%3Dr%5Comega)
Where
r is radius of the circular path
ω is angular speed
The merry-go-round is rotating at a constant angular speed. Let the new distance from the center of the circular platform is r'
r' = 2r
New angular speed,
![v'=r'\omega'\\\\v'=(2r)\omega\\\\v'=2r\omega\\\\v'=2v](https://tex.z-dn.net/?f=v%27%3Dr%27%5Comega%27%5C%5C%5C%5Cv%27%3D%282r%29%5Comega%5C%5C%5C%5Cv%27%3D2r%5Comega%5C%5C%5C%5Cv%27%3D2v)
New angular speed is twice that of the Chuck's speed.
