Answer:

Diode

Explanation:

The rectifier is a device which is used to convert alternating current into direct current.

There are two types of rectifiers.

Half wave rectifier and full wave rectifier.

To convert alternating current completely into direct current, full wave rectifier is used.

A rectifier consists of diode.

As we know that equivalent resistance of a capacitor for an AC circuit is given as

X_c = \frac{1}{\omega C}

so here for an AC circuit capacitor will provide less resistance to AC component of the current

While for DC as we know it has ZERO frequency

so we will have large resistance

so here we will have to use capacitor as a filter circuit which will separate AC component of current from the DC current

So correct answer will be

CAPACITOR

A train is moving in the positive direction down a track. First the train speeds up, and then it slows down. What is its acceler
tatuchka [14]
C.

The train first sped up, giving it a positive acceleration in the beginning. This eliminates D since that choice states that it begins with a negative acceleration. This also eliminates B since that choice states that the train only had a negation acceleration.

Next, the train slows down, giving it a negative acceleration. We’re looking for the answer choice that starts with a positive acceleration and ends with a negative one. This makes C the correct answer. Hope this helps!

A 105 kg astronaut carrying a 16 kg tool bag finds himself separated from his spaceship by 18 m and moving away from the spacesh
Ratling [72]

Answer:

T=22.5sec

Explanation:

From the question we are told that:

Mass of astronaut m_a=105kg

Mass of tool m_t=16kg

Distance d=18m

Velocity of separation v_s= 0.1m/s

Velocity of tool bag v_t=4.5m/s

Generally the equation for momentum is mathematically given by

 P=mv

Therefore

Initial Momentum before drop

 P_1=0.1(105+16)

 P_1=12.1

Initial Momentum after drop

 P_2=-16(4.5)+105V

Therefore

Since P_1=P_2

 -72+105V=12.1

 V=0.8m/s

Generally the equation for Time T is mathematically given by

 T=\frac{d}{V}

 T=\frac{18}{0.8}

 T=22.5sec

What is 1113.28 in a sig fig?
Afina-wow [57]

Answer:

6 significant figure

Explanation:

The digits 111328 all are 6 figures with no figure being zero, neither zero after the other digits. In this case, all the numbers are significant and since they are only six numbers, then this is a six significant figure. In case we add another zero after digit 8, the zero is not significant but if added either infront of 8 or 2, the zero becomes significant.

An ice cube of mass 50.0g can slide without friction up and down a 25.0 degree slope. The ice cube is pressed against a spring a
sergejj [24]

Answer:

Explanation:

Given

mass of ice cube m=50 gm

inclination \theta =25^{\circ}

Spring constant k=25\ N/m

initial compression x=0.1 m

Suppose Initially the cube is at the datum  and it moves h height after release

So Elastic Potential Energy of Spring will convert to Potential Energy of cube

\frac{1}{2}kx^2=mgh

\frac{1}{2}\times 25\times (0.1)^2=50\times 10^{-3}\times 9.8\times h

h=0.255 m

so final Potential Energy will be =mgh=0.05\times 9.8\times 0.255=0.125 J

Initial Potential Energy=0 J

B.Initially spring is at compression so energy associated with it is its Elastic Potential Energy i.e. 0.125 J

Final Energy=0 J
