A)At 5.5sec car is at rest because the distance is same as at 5.0sec .
B) At t= 2sec where the distance covered by a car is 20m.
The speed of the car is 10m/s
C) Average speed
4/Savg= 0.14+6.4+5.8+5p.27
Savg = 0.227 m/s

Rubbing both pieces cause each piece to have a negative charge.
When two parts have the same they repel each other, so holding one piece up tot he end of the other piece would push it away.
Because one piece is held in the middle by a string, it would rotate the piece in a circle.
If they held the piece to the other end of the one held by a string it would start to rotate in the opposite direction.
Answer:
White light contains seven colors, which are separated by the prism.
White light reacts with chemicals in the air to produce seven colors.
Explanation:
It was first observed by Sir Issac Newton, that when white light is passed through a prism, an elongated, coloured patch of light is obtained on a screen placed behind the prism. The seven colours obtained constitute the spectrum of white light.
In nature, white light is separated into its constituent wavelengths when white light interacts with substances in the atmosphere.
As per law of Heisenberg uncertainty law
product of uncertainty in position and uncertainty in momentum will be constant
now plug in all data
So above is the uncertainty in velocity of the object
Answer:
newton's 2nd law
Explanation:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
