Complete Question

A step-up transformer is connected to a generator that is delivering 197 v and 113 A. The ratio of the turns on the secondary to the turns on the primary is 600 to 5. What is the voltage across the secondary

Answer:

The voltage is $V_s = 23640 \ V$

Explanation:

From the question we are told that

The voltage is $V_p = 197 \ V$

The current is $I = 113 \ A$

The number of turn on the secondary is $N_s = 600 \ turns$

The number of turn on the primary is $N_p = 5 \ turns$

Generally from the Transformer Turns ratio equation

$\frac{N_s}{N_p} = \frac{V_s}{V_p}$

=> $\frac{ 600}{ 5} = \frac{V_s}{197 }$

=> $V_s = 23640 \ V$

An Airbus A320 jetliner has a takeoff mass of 75,000 kg. It reaches its takeoff speed of 82 m/s (180 mph) in 35 s. What is the t

timofeeve [1]

Answer:

175.5 kN

Explanation:

We find the acceleration of the Airbus A320 jetliner from,

a = (v - u)/t where u = initial velocity of jetliner = 0 m/s (since it starts from rest), v = final velocity of jetliner = 82 m/s and t = time for velocity change = 35 s

So a = (v - u)/t = (82 m/s - 0 m/s)/35 s = 82 m/s ÷ 35 s = 2.34 m/s²

Now, the thrust of the engines on the jetliner T = ma where m = mass of jetliner = 75,000 kg and a = acceleration of jetliner = 2.34 m/s²

T = ma

= 75,000 kg × 2.34 m/s²

= 175500 N

= 175.5 kN

Light from a helium-neon laser (λ=633nm) passes through a circular aperture and is observed on a screen 5.80 mm behind the apert

Helga [31]

Explanation:

Whenever the light passes through hole or slit then it tends to bend that is actually a diffraction. It will then made the interference pattern of light and dark bands that due to constructive and destructive interference.

So by using the equation of diffraction,

dsinA = nL

SinA is a geometric component it can be written as,

$d\frac{y}{x} = nL$
