There are six steps on the formation of a solar system. 1) solar nebula
2) planetesimals form. 3) planetesimals accrete into protoplanest 4) terrestrial planets form 5) gas giants form 6) formation or organization of smaller objects (moon, asteroids, comets)
Answer:
Explanation:
Magnetic field is oriented downwards . area of loop is decreasing so downward flux is decreasing . To increase the downward flux , current induced will be clockwise so that flux generated by induced current increases the downwards flux . It is in accordance with Len'z law.
moving,
the sun is a different "observer"
I think to an observer outside the train, the speed of the ball will actually look like more than the speed of the train.

The force of friction is equal to the product of the vertical force applied by the surface to the object in the coefficient of friction.

In this question ,
surface vertical force = Weight of the object
Thus ;
svf = ( mass ) × ( gravity acceleration )
_________________________________
If gravity acceleration is 10 :
svf = 10 × 10 = 100 N
So ;
frictional force = 100 × 0.20
frictional force = 20 N
##############################
If gravity acceleration is 9.8 :
svf = 10 × 9.8 = 98 N
So ;
frictional force = 98 × 0.20
frictional force = 19.6 N
