Explanation:
It is given that, the field near a typical pulsed-field machine rises from 0 T to 2.5 T in 200 μs
Change in magnetic field,
Change in time,
Diameter, d = 2.3 cm
Radius, r = 0.0115 m
Emf is induced in the ring as the field changes. It is given by :
E = 5.19 volts
So, the emf induced in the ring is 5.19 volts. Hence, this is the required solution.
Answer:
the maximum intensity of an electromagnetic wave at the given frequency is 45 kW/m²
Explanation:
Given the data in the question;
To determine the maximum intensity of an electromagnetic wave, we use the formula;
=
ε₀cE
²
where ε₀ is permittivity of free space ( 8.85 × 10⁻¹² C²/N.m² )
c is the speed of light ( 3 × 10⁸ m/s )
E is the maximum magnitude of the electric field
first we calculate the maximum magnitude of the electric field ( E )
E = 350/f kV/m
given that frequency of 60 Hz, we substitute
E = 350/60 kV/m
E = 5.83333 kV/m
E = 5.83333 kV/m × (
)
E = 5833.33 N/C
so we substitute all our values into the formula for intensity of an electromagnetic wave;
=
ε₀cE
²
=
× ( 8.85 × 10⁻¹² C²/N.m² ) × ( 3 × 10⁸ m/s ) × ( 5833.33 N/C )²
= 45 × 10³ W/m²
= 45 × 10³ W/m² × (
)
= 45 kW/m²
Therefore, the maximum intensity of an electromagnetic wave at the given frequency is 45 kW/m²

<u>Question: </u>
How much (in US dollars) will we spend properly on fuel on our trip? Express the answer numerically in US dollars to three significant figures.
Let us convert the unit price from the euro to USD. Currently, the exchange rate of 1 euro is 1.13 USD.
The term euro is crossed out.
After currency conversion, the average fuel cost is 1.20119 USD/liter.
We need 6.00 liters of fuel during the trip.
The term liter is crossed out.
We rounded up to three significant figures. Hence, the cost that we will spend on fuel on our trip is as much
<em>Want to follow another way? Let's see.</em>
The term liter is crossed out.
The term euro is crossed out.
We get a similar result, i.e.,
