A wire that is 0.86 meters long is moved perpendicularly through a constant magnetic field of strength 0.035 newtons/amp·meter a
GaryK [48]
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec
emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v

The electric potential at a certain location from a point charge can be represented by V. What is the value of the electric pote
adoni [48]
<h2>Answer:</h2>

If you triple the charge, the electric potential is 3V.

<h2>Explanation:</h2>

If you triple the charge, the electric potential is 3V. Put another way, the value of the electric potential at the same location is tripled if the strength of the charge is tripled.

<em>But why this is true?</em>

Well, the potential V due to a single point charge q is:

V=\frac{1}{4\pi\varepsilon_{0}}\frac{q}{r}

If the strength of the charge is tripled means that our new q1=3q, therefore:

V=\frac{1}{4\pi\varepsilon_{0}}\frac{3q}{r}

V=3\frac{1}{4\pi\varepsilon_{0}}\frac{q}{r}

So you can see that in fact if you triple the charge, the electric potential is 3V.

How long will it take a car to go from 0 to 45 km/hr if they are accelerating at 5 km/hr/s?
Mandarinka [93]

Answer:

9 seconds

Explanation:

acceleration =  \frac{final \: speed - initial \: speed}{time \: taken}

5km/ hr/ s =  \frac{45 - 0 (km/ h)}{t}

cross multiplying

5t = 45 secs \\ t = 9 \: secs

it will take 9secs for the car to go from 0 to 45 km/ h
