You need to design a 60.0-Hz ac generator that has a maximum emf of 5500 V. The generator is to contain a 150-turn coil that has
olchik [2.2K]

Answer:

So magnetic field will be equal to 0.1144 T  

Explanation:

We have given frequency f = 60 Hz

Maximum emf e = 5500 volt

Number of turns N = 150

Area A=0.85m^2

Emf generated in ac generator is given e=NBA\omega sin(\omega t)

For maximum emf sin(\omega t)=1

So maximum emf will be equal to e=NBA\omega

B=\frac{e}{NA\omega }=\frac{5500}{150\times 2\times 3.14\times 60\times 0.85}=0.1144T

So magnetic field will be equal to 0.1144 T

Over a span of 6.0 seconds, a car changes its speed from 89 km/h to 37 km/h. What is its average acceleration in meters per seco
faltersainse [42]

Answer: Average acceleration is -2.407 \frac{m}{s^{2}}

 

Explanation:

Average acceleration is equal to change in velocity divided by time taken

therefore, a=\frac{Vf-Vi}{t}

=> a=\frac{37-89}{6}\times \frac{5}{18}\frac{m}{s^{2}} = -2.407 \frac{m}{s^{2}}
