Explanation:
he formula for IMA of a first-class lever is effort-distance/resistance-distance.
Stored mechanical energy is energy stored and awaiting to be used and mechanical energy is the energy that was stored being used.
Answer:
the storm knocked down trees creating a dam blocking the path for water to move
Explanation:
gold is usually found in pure form because it is not reacting with other chemicals naturally.
Just use the Heisenberg Uncertainty principle:
<span>ΔpΔx = h/2*pi </span>
<span>Δp = the uncertainty in momentum </span>
<span>Δx = the uncertainty in position </span>
<span>h = 6.626e-34 J s (plank's constant) </span>
<span>Hint: </span>
<span>to calculate Δp use the fact that the uncertainty in the momentum is 1% (0.01) so that </span>
<span>Δp = mv*(0.01) </span>
<span>m = mass of electron </span>
<span>v = velocity of electron </span>
<span>Solve for Δx </span>
<span>Δx = h/(2*pi*Δp) </span>
<span>And that is the uncertainty in position. </span>
