Answer:

A. The frequencies of EMR it emits depend on its temperature

B. It emits only one frequency of EMR

C. It absorbs most of the EMR it receives

Explanation:

  • A blackbody is an object that absorbs most of the electromagnetic spectrum of energy that falls on it.
  • According to law to reradiates most of the available energy back on top the outer space at an efficiency of 100% and thus radiation may be in the visible range of temperature than are in 1000K.

Both Josef Loschmidt and Amedeo Avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios
lbvjy [14]

The  Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound.

<h3>What is the  Avogadro’s number?</h3>

The  Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound. The numerical value of the  Avogadro’s number is obtained as 6.02 x 10^23 and consists of the atoms, molecules and ions in the compound.

The scientist Josef Loschmidt strengthened the  Avogadro’s number  by  obtaining the number of particles in one cubic centimeter of gas under standard conditions.

Calculate the magnitude of the particle accelerator's magnetic field that causes an ionized helium atom (+2q e) with a momentum
trasher [3.6K]

Answer:

The magnetic field of the particle is 1.5 T.

(C) is correct option.

Explanation:

Given that,

Momentum of particle p=4.8\times10^{-16}\ kg m/s

Radius = 1.0 km

Charge of the particle q=2\times1.6\times10^{-19}\ C

We need to calculate the magnetic field

Using relation of radius of path in magnetic field

r=\dfrac{mv}{qB}

Here mv = p

B=\dfrac{p}{qr}

Put the value into the formula

B=\dfrac{4.8\times10^{-16}}{1000\times2\times1.6\times10^{-19}}

B=1.5\ T

Hence, The magnetic field of the particle is 1.5 T.
