Answer:
The law of conservation of energy
Explanation:
From diagram 2, only half of the cycles of alternating current can pass from the unknown component.
It has to be a diode because a diode can only allow current flow in one direction in circuits.
They are both sites of new cell formation.

I am going to assume that there is a typo for the number of joules of energy. Doing a google search for this exact question showed this question multiple times with a value of 4942 joules which makes sense given how close the "o" key is to the "9" key. Because of this, I will assume that the correct value for the number of joules is 4942. With that in mind, here's the solution.
The gravitational potential energy is expressed as the mass multiplied by the height, multiplied by the local gravitational acceleration. So:
E = MHA
Solving for M, the substituting the known values and calculating gives:
E = MHA
E/(HA) = M
4942/(6.15*9.8) = M
4942/60.27 = M
81.99767712 = M
Rounding to 3 significant figures gives 82.0 kg</span>
Answer:
The object displacement is 0 meters.
Explanation:
Because the expression for the object position as function of time is:
At t= 3.0=t2 seconds the x-position of the object is:
and at t=1.0=t1 seconds the x-position of the objects is:
The total displacement () of the object between t2 and t1 is the difference between x(3.0s) and x(1.0s):
The displacement of the object is zero!!!
