The value of the diameter of the hydrogen atom as we have it in this experiment is accurate because it is very close to the true value.
<h3>What is accuracy?</h3>
The term accuracy refers to how close the measured value is to the true value. The true value is the same as the accepted value. In this case, the true value of the diameter of a Hydrogen atom is 10 nm.
The fact that is observed value is obtained to be 10.1 nm implies that the value of the diameter of the hydrogen atom as we have it in this experiment is accurate because it is very close to the true value.

The oxygen attracts the shared electrons more strongly than the hydrogen atoms do.
Momentum is conserved after the collision
Momentum of 2 Kg before collision = 2 * 3 = 6
Momentum of 4 kg before collision = 4 * -3 = -12
so 6 + -12 = 2 * -4 + 4 *x where x is velocity of 4kg marble.
4x - 8 = -6
4x = 2
x = 0.5
Velocity of 4 kg marble is 0.5 m/s after collision
The 2 kg marble will move in the opposite direction to which it was moving before the collision.
