Sometimes a new experimental result may seem to go against a well-established scientific theory. Which statement BEST describes
MrMuchimi
The best thing to do in this case is to redo the experiment and re record the info, it has to be precise and accurate so you also have to check if your procedure is correct. If the results are both accurate and precise then you have to report your findings to the committee of that specific field. <span />

Which one of the following phrases best describes the electric potential of a charged particle?
vfiekz [6]

Answer:

D.The potential energy per unit charge

Explanation:

Electric potential of a charged particle:

It is scalar quantity because it has magnitude but it does not have direction.

It is the amount of work done required to move a unit positive charge from reference point to specific point in the electric field without producing any acceleration.

Mathematical representation:

V=\frac{W}{Q_0}

Where W= Work done

Q_0= Unit positive charge

Other formula to calculate electric field:

V=\frac{KQ}{r}

Where K=\frac{1}{4\pi \epsilon_0}

It can be defined as potential energy per unit charge.

Hence, option D is true.

Recall the raisin cake model of the universe. Our universe is expanding between the galaxies. You measure the recession velocity
Rina8888 [55]

Explanation:

Recession velocity of a galaxy is related to the distance at which the galaxy is located. This relationship is given by the hubble constant, as follows:

v_r=HD

Hubble constant is aproximate 70\frac{km/s}{Mpc} and 1 megaparsec (Mpc) is 3.26*10^6 light years. Rewriting for D:

D=\frac{v_r}{H}

For galaxy A:

D=\frac{2000\frac{km}{s}}{70\frac{km/s}{Mpc}}\\\\D=28.57Mpc\\\\D=28.57Mpc*\frac{3.26*10^6ly}{1Mpc}=9.31*10^7ly

For galaxy B:

D=\frac{6000\frac{km}{s}}{70\frac{km/s}{Mpc}}\\\\D=85.71Mpc\\\\D=85.71Mpc*\frac{3.26*10^6ly}{1Mpc}=2.79*10^8ly
