Auhf antenna is oriented at an angle of 47o to a magnetic field that changes at a rate of 0.23 t/s. what is the induced emf of the antenna if it has a diameter of 13.4 cm? o 5.4 mv ? 2.2 ? 0027 ?

Induced emf,

Explanation:

It is given that,

Rate of change of magnetic field,

A UHF antenna is oriented at an angle of 47° to a magnetic field, θ = 47°

Diameter of the antenna, d = 13.4 cm

Radius, r = 6.7 m = 0.067 m

We need to find the induced emf of the antenna. It is given by :

Where

= magnetic flux,

So,

B = magnetic field

So, the induced emf of the antenna is 2.2 mV. Hence, this is the required solution.

scorpions are,

c.arachnids

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders

happy to

pls mark as brainliest.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
