Answer:
7.33 rounded
Explanation:
Speed = distance divided time
S = d/t
Suppose a Rollerblade racer finished a 132 meter race in 18 seconds. What is the average speed of the Rollerblade racer?
S = 132 divided 18
Speed = 7.33 rounded
<span>When you bring a charged object, such as your balloon, near a neutral object that is classified as an insulator, than a temporary charge is induced in the neutral object. If the charged object is positive, then electrons in the neutral object will be attracted toward the charged object, creating a temporary imbalance of charges in the neutral object.</span>
The correct answer for the question that is being presented above is this one:
Phi = BAsin(theta)
<span>1. Phi(i) = BA </span>
<span>2. Phi(f) = 0 </span>
3. EMF = N(phi(i)-phi(f))/deltat
Here are the follow-up questions:
<span>1. What is the total magnitude Phi_initial of the magnetic flux through the coil before it is rotated? </span>
<span>2. What is the magnitude Phi_final of the total magnetic flux through the coil after it is rotated? </span>
<span>3. What is the magnitude of the average emf induced in the coil?</span>
Answer:
v = 42.33 m/s
Explanation:
The time difference between two pulses that are emitted by Police is observed in the interval

now the speed of the electromagnetic wave is given as

now the distance traveled by them



so distance of speeding vehicle covered for round trip of wave is 38.1 m
now for one trip it is given as d = 19.05 m
now the speed of the vehicle is given as
