A magnetic field directed along the x-axis changes with time according to B (0.06t2+2.25) T, where t is in seconds. The field is

Gemiola [76]

Answer:

$E = 2 \times 10^{-3} V$

Explanation:

As we know that rate of change in flux will induce EMF

So here we can

$EMF = \frac{d\phi}{dt}$

now we have

$EMF = \pi r^2\frac{dB}{dt}$

now we also know that induced EMF is given by

$\int E. dL = \pi r^2\frac{dB}[dt}$

$E (2\pi r) = \pi r^2\frac{dB}{dt}$

$E = \frac{r}{2}(\frac{dB}{dt})$

now plug in all values in it

$E = \frac{0.0133}{2}(0.12 t)$

$E = 8 \times 10^{-4} (2.50) = 2 \times 10^{-3} V/m$

A forest ranger might be ranked as being high in what type of intelligence?

Drupady [299]

<h2>Answer:</h2>

<u>A forest ranger might be ranked as being high in </u><u>Naturalistic</u><u> intelligence.</u>

<h2>Explanation:</h2>

Naturalistic intelligence is the type of intelligence that relates the activities of people that how sensitive an individual is to nature and the world. Zookeepers, biologists, gardeners, and veterinarians are among those people who have a higher capability of having high naturalist intelligence. Similarly a ranger who is fighting in forests must also be kept in the same category and he might be ranked as being high in the field of Naturalistic Intelligence.
