4 0

Answer:

The electromagnetic radiation with the shortest wavelength are gamma rays.

Explanation:

Photons are the particles that constitute light and its kwnow that lights propagates as electromagnetic waves.

The electromagnetic spectrum is the distribution of radiation due to the different frequencies at which it radiates and its different intensities, that radiation is formed by electromagnetic waves, which are transverse waves formed by an electric field and a magnetic field perpendicular to it.

The distribution of the radiation in the electromagnetic spectrum can also be given in wavelengths, but it is more frequent to work with it at frequencies, the highest being that of gamma rays, followed by X-rays, ultraviolet rays and the visible region , and those of lower frequencies, which correspond to infrared, microwave and radio waves.        

The energy given for each wavelength can be found by means of the following equation.

E = h\nu  (1)

but c = \lambda \cdot \nu

\nu = \frac{c}{\lambda}

E = \frac{hc}{\lambda}   (2)

Where E is the energy, h is the planck's constant and \lambda is the wavelength.

                   

So, it can be see in equation 2 that when the wavelength increases the energy decreases (inversely proportional).

Hence, the electromagnetic radiation with the shortest wavelength are gamma rays.

A transformer has a primary voltage of 115 V and a secondary voltage of 24 V. If the number of turns in the primary is 345, how
Nata [24]

Answer:

C. 72

Explanation:

Transformer: A transformer is an electromagnetic device that uses the property of mutual inductance to change the voltage of alternating supply.

In a ideal transformer,

Vs/Vp = Ns/Np ............................................. Equation 1

Where Vp = primary voltage, Vs = secondary voltage, Ns = Secondary turn, Np = primary turn.

Making Ns the subject of the equation,

Ns =(Vs/Vp)Np .......................................... Equation 2

Given: Vs = 24 V, Vp = 115 V, Np = 345.

Substitute into equation 2

Ns = (24/115)345

Ns = 72 turns.

Thus the number of turns in the secondary = 72 turns.

The right option is C. 72

What do we call an object displaced by an unbalanced Force,
Accelerated object,


And we also know that,
Due to acceleration, An object displaces.

But I'll use Newton's 1st law to prove it,
Which is, An object will remain in rest or in uniform motion until it is compelled by an external Force.

As per the his law,
The cat will remain on the dashboard of that moving car until it is compelled by Air Force (external Force).

Likurg_2 [28]

Answer:

The magnetic field strength is 3.9 x 10⁻³ T

Explanation:

The equation for the magnetic field strength produced by a long straight current-carrying wire is written as;

B = \frac{\mu_o I }{2\pi r}

Where;

μ₀ is constant = 4π x 10⁻⁷ N/A

I is the maximum current = 20 A

r is the radius of the wire = 2.053/2 = 1.0265 mm = 1.0265 x 10⁻³ m

Substitute in this values into the equation above;

B = \frac{4 \pi X10^{-7} X 20}{2\pi X 1.0265X10^{-3} } \\\\B =3.9 X10^{-3} T

Therefore, the magnetic field strength is 3.9 x 10⁻³ T
