Alpha particles which have a charge +2e and mass 6.64 ✕ 10−27 kg are initially at rest and are fired directly at a stationary lead nucleus (charge +82e) at a speed of 1.95 ✕ 107 m/s. determine the distance of closest approach (in fm) before the alpha particle reverses direction. assume the lead nucleus remains stationary. assume the alpha particles are initially very far from a stationary lead nucleus.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

false

explanation:

boats, things on boats luggage are way more heavy then water.

b would be the answer
