How can we reduce the ripple factor of a bridge recitifier from 0.48 to 0.1 approximately ?
padilas [110]
U can try to use capacitor , the value of capacitor depends on circuit

ripple factors signifies the ac components, by def its ratio of rms value of ac component to value of dc component
so in order to reduce use of a capacitor which denies the sudden changes in voltage, which is the charracteristic of Ac signals

hope this helps

How fast and in what direction must galaxy A be moving 17 an absorption Line found at 500 nm for a stationary galaxy 1s shifted
emmainna [20.7K]

Answer:

v = 0.22 c and wavelength is decrease so galaxy A is move away from stationary galaxy

v = 0.095 c and wavelength is increase so galaxy B come toward stationary galaxy

Explanation:

Given data

found = 500 nm

shifted A = 400 nm

shifted B = 550 nm

to find out

How fast and in what direction is galaxy

solution

we use here formula  that is

(λ) shifted = √(1-β / 1+β)  (λ)found

1-β / 1+β =  (4/5)²         ..................1

1-β / 1+β =  16 / 25

β = 0.22

v/c = 0.22

v = 0.22 c

here wavelength is decrease so galaxy A is move away from stationary galaxy

and

here according to equation 1

and we use shifted 550 nm

so

1-β / 1+β =  (5.5/5)²

1-β / 1+β =  30.25 / 25

β = 0.095

so  v/c = 0.095

v = 0.095 c

here wavelength is increase so galaxy B come toward stationary galaxy

A pitcher tosses a baseball in the positive direction with a speed of 12 m/s. If the ball stops after 4 seconds, what is the ave
meriva

Answer:

option c is correct

Explanation:

we know that time rate of change of velocity is called acceleration

so a=v/t

a=12/4

a=3m/s²

In a science fiction movie, a lone astronaut with a mass of 75 kg is stranded outside their spaceship with a thruster pack that
irinina [24]

Answer:

Explanation:

The momentum will be conserved .

M₁ V₁ =M₂V₂

2.3 x 15 = 75 x V

V = .46 m/s

velocity of astronaut will be 0.46 m/s after the throw of wrench .

Impulse = change in momentum

= 75 x .46 - 0

= 34.5 kg m/s

Impulse = force x time

34.5 = force x .12

force = 34.5 / .12

= 287.5 N

average acceleration

= force / mass

= 287.5 / 75

= 3.83 m /s²
