Answer:

<em>Gamma rays with high energies</em>

<em>Explanation:</em>

<em>The frequency of t most  energetic bursts has been estimated at about</em>

<em>3.0 × 1021 Hz.  The light speed estimated to be  is 3 × 108 m/s</em>

<em>R=Then the wavelength of the gamma rays is</em>

<em>c = 3.00 x 10^8 m/s </em>

<em>f = 3.0 x 10^21 Hz </em>

<em> λ = c/f </em>

<em>λ = 3.00 x 10^8 / 3.0 x 10^21 </em>

<em>λ = 3.0 x 10^-13 nm</em>

Answer: of gamma rays with high energies.

Explanation:Gamma-ray bursts are extremely energetic explosions that have been observed in distant galaxies. They are the brightest electromagnetic events known to occur in the universe.

The frequency of the most energetic bursts has been measured at around 3.0×1021 3.0 × 10 21 Hz.

A velocity selector in a mass spectrometer uses an electric field of 4.4 x 105 V/m. What magnetic field strength (in Tesla) is n
Brut [27]

Answer:

  B = 9.16 10⁻²  T

Explanation:

The speed selector is a configuration where the electric and magnetic force has the opposite direction, which for a specific speed cancel

       q v B = q E

       v = E / B

       B = E / v

Let's calculate

      B = 4.4 10⁵ / 4.8 10⁶

      B = 9.16 10⁻²  T

Consider a 150 turn square loop of wire 17.5 cm on a side that carries a 42 A current in a 1.7 T. a) What is the maximum torque
ankoles [38]

Answer:

(a) 328 Nm

(b) 79.35 Nm

Explanation:

N = =150, side = 17.5 cm = 0.175 m, i = 42 A, B = 1.7 T

A = side^2 = 0.175^2 = 0.030625 m^2

(a) Torque = N x i x A x B x Sinθ

For maximum torque, θ = 90 degree

Torque = 150 x 42 x 0.030625 x 1.7 x Sin 90

Torque = 328 Nm

(b) θ = 14 degree

Torque =  150 x 42 x 0.030625 x 1.7 x Sin 14

Torque = 79.35 Nm
