Answer:
Explanation:
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC), a process known as rectification. Rectifiers have many uses including as components of power supplies and as amplitude modulation detectors (envelope detectors) of radio signals. Rectifiers are most commonly made using solid state diodes but other type of components can be used when very high voltages or currents are involved. When only a single diode is used to rectify AC (by blocking the negative or positive portion of the waveform), the difference between the term diode and the term rectifier is simply one of usage. The term rectifier describes a diode that is being used to convert AC to DC. Most rectifier circuits contain a number of diodes in a specific arrangement to more efficiently convert AC power to DC power than is possible with only a single diode.

Answer: the earth
Explanation: Earth exerts a gravitational pull on the moon 80 times stronger than the moon's pull on the Earth. Over a very long time, the moon's rotations created fiction with the Earth's tugging back, until the moon's orbit and rotational locked with Earth.
and that's why the earth pulls the moon
The Earth pulling on the moon and the moon pulling on the Earth exert the same amount of force on each other due to Newton's third law of motion.
In terms of force, the Earth pulling on the Moon and the Moon pulling on the Earth exert the same amount of force on each other. This is because of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. So, while the Earth's gravitational force pulls the Moon towards it, the Moon's gravitational force also pulls the Earth towards it with an equal amount of force.
Newton's third law of motion states that for every action, there is an equal and opposite reaction. In the context of the gravitational interaction between the Earth and the Moon, the forces they exert on each other are equal in magnitude and opposite in direction.
The Earth pulls on the Moon with a gravitational force, and, according to Newton's third law, the Moon simultaneously pulls on the Earth with an equal gravitational force. These forces are sometimes referred to as "action and reaction pairs." The force that the Earth exerts on the Moon is often called the gravitational attraction of the Earth on the Moon, and vice versa.

Explanation:
From the question we are told that
The mass of the stone is
The height above the top of the water is
The depth of the well is
The gravitational potential of the stone before it was released is
substituting values
The gravitation potential of the stone when it reaches the bottom of the well is
The negative shows that the potential energy of the stone as compared to the earth is reducing
substituting values
The change in the systems gravitational potential is
substituting values
Answer:
The change in momentum is
Explanation:
From the question we are told that
The mass of the probe is
The location of the prob at time t = 22.9 s is
The momentum at time t = 22.9 s is
The net force on the probe is
Generally the change in momentum is mathematically represented as
The initial time is 22.6 s
The final time is 22.9 s
Substituting values
Answer:
doubling the size of the tax more than doubles the deadweight loss while less than doubles the revenue generated
Explanation:
(a)
The quantity of rooms rented before tax, Q1 = 1000 rooms.
The quantity of rooms rented after the imposition of tax Q2 = 900 rooms.
Size of the tax = $10
Price paid by buyer = $108
Price received by seller = $98
Deadweight loss = 1/2 x (Q2 — Q1) x (size of the tax)
Deadweight loss = 1/2 x (1000 — 900) x ($10) = $500
Tax revenue generated = size of tax * (Q2) = $10 x (900) = $9000
b)
The quantity of rooms rented before tax, Q1 = 1000 rooms
The quantity of rooms rented after the imposition of tax, Q2 = 800 rooms Size of the tax = $20
Price paid by buyer = $116
Price received by seller = $96
Deadweight loss = 1/2 x (Q2 — Q1) x (size of the tax)
New Deadweight loss = 1/2 x (1000 — 800) x ($20) = $2000
Thus, dead weight loss quadruples post doubling the size of tax. New Tax revenue generated = size of tax x (Q2) = $20 x (800) = $16000 Thus, revenue generated less than doubles post doubling the size of tax.
Answer:
Explanation:
Students must push harder on the handle when the leads of the generator are connected across the wire with the lowest resistance.
This is because turning the handle at a given constant rate produces a constant voltage across the leads, regardless of what is connected to the leads.
So, when turning the handle at a constant rate, lab students must push harder in case where there is a greater current through the connected wire.
