<span>The full wave rectifier is a circuit that converts an ac voltage into a pulsating dc voltage </span><span>by using every half-cycle of the input voltage.
Including a full-wave rectifier in an AC circuit will yield a  </span>continuous direct current.
A full wave rectifier consists of two diodes, one for each half of the wave and a multiple winding transformer.

You pull straight up on the string of a yo-yo with a force 0.24 N, and while your hand is moving up a distance 0.17 m, the yo-yo
Alex

Answer:

The transnational kinetic energy of the yo-yo is 0.083 J.

Explanation:

Given that,

Force=0.24 N

Distance in up= 0.17 m

Distance in down = 0.26 m

Mass of yo-yo = 0.057 kg

Initial speed = 2.4 m/s

Suppose we find the increase in the transnational kinetic energy of the yo-yo

The transnational kinetic energy is equal to the change in potential energy.

We need to calculate the transnational kinetic energy of the yo-yo

Using conservation of energy

\Delta K.E=(mg-F)h

Where, F = force

h = height

m = mass of yo-yo

Put the value into the formula

\Delta K.E=(0.057\times9.8-0.24)\times0.26

\Delta K.E=0.083\ J

Hence, The transnational kinetic energy of the yo-yo is 0.083 J.

A large rocket has a mass of 2.00×10⁶ kg at takeoff, and its engines produce a thrust of 3.50×10⁷ N. Find its initial accelerati
Kazeer [188]

Answer:

17.5 m/s²

1.90476 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

Force

F=ma\\\Rightarrow a=\frac{F}{m}\\\Rightarrow a=\frac{3.5\times 10^7}{2\times 10^6}\\\Rightarrow a=17.5\ m/s^2

Initial acceleration of the rocket is 17.5 m/s²

v=u+at\\\Rightarrow \frac{120}{3.6}=0+17.5t\\\Rightarrow t=\frac{\frac{120}{3.6}}{17.5}=1.90476\ s

Time taken by the rocket to reach 120 km/h is 1.90476 seconds

Change in the velocity of a rocket is given by the Tsiolkovsky rocket equation

\Delta v=v_{e}\ln \frac{m_0}{m_f}

where,

m_0 = Initial mass of rocket with fuel

m_f = Final mass of rocket without fuel

v_e = Exhaust gas velocity

Hence, the change in velocity increases as the mass decreases which changes the acceleration

Heya!!!


Answer to your question:
C.
Energy transferred to a machine equals energy transferred from it.

Law of conservation of energy states that total energy of an isolated system remains constant
Energy can neither be created nor be destroyed. Machine follows the same rule.

Hope it helps ^_^
