False! The ability to cause change is energy, not matter. <span />
Answer:
Explanation:
Since the particle is experimenting a constant acceleration, the displacement can be found by using this formula:
Since 
, the equation is simplified to this form:
Then, the displacement is now isolated:
Terms are replaced herein:
Answer: If the force stays the same, the acceleration would decrease
Answer:
This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge. For example, when you shuffle your feet across a carpet, electrons can transfer onto you, building up a static charge on your skin.
Explanation:
This is because the rubbing releases negative charges
Answer:
θ = 41.8º
Explanation:
This is an internal total reflection exercise, the equation that describes this process is
sin θ = n₂ / n₁
where n₂ is the index of the incident medium and n₁ the other medium must be met n₁> n₂
θ = sin⁻¹ n₂ / n₁
let's calculate
θ = sin⁻¹ (1.00 / 1.50)
θ = 41.8º
