A proton moves in a circular orbit of radius 65 cm perpendicular to a uniform magneticfield of magnitude 0. 75 t
stepan [7]

The speed of the proton is \rm 4.7 \times 10^7 \ meter \ per \ second.

<h3>What is the speed of the proton? </h3>

For the speed of a proton that has been accelerated from rest, we would apply the work-energy theorem:

A proton moves in a circular orbit with a radius of 65 cm that is perpendicular to a uniform magnetic field of magnitude 0.75 T.

The speed of the proton is given by the following formula;

\rm V=\dfrac{2\pi R}{T}\\\\V=\dfrac{2 \times  3.14 \times  0.65m }{87.4ns}\\\\V =4.7 \times 10^7 \ meter \ per \ second

Hence, the speed of the proton is \rm 4.7 \times 10^7 \ meter \ per \ second.

A seasonal index for a monthly series is about to be calculated on the basis of three years’ accumulation of data. The three pre
yarga [219]

Answer:

0.684

Step-by-step explanation:

According to the scenario, computation of the given data are as follows

Seasonal index = Average value for July ÷ Average over all months

Where, Average value for July = ( 110 + 150 + 130 ) ÷ 3

= 390 ÷ 3 = 130

And, average over all months = 190

So by putting the value in the formula, we get

Seasonal index = 130 ÷ 190

= 0.684211 or 0.684

Hence, approximate seasonal index for July is 0.684.
