During the first 6 years of its operation, the Hubble Space Telescope circled the Earth 37,000 times, for a total of 1,280,000,0

00 km. It takes the Hubble Space Telescope about 90 minutes to make one complete orbit. How fast is it traveling (in units of km/min)? Remember, distance = time x speed. Round your answer to the nearest integer and don't include the units for this answer.

Answer:

v = 384km/min

Explanation:

In order to calculate the speed of the Hubble space telescope, you first calculate the distance that Hubble travels for one orbit.

You know that 37000 times the orbit of Hubble are 1,280,000,000 km. Then, for one orbit you have:

d=\frac{1,280,000,000km}{37,000}=34,594.59km

You know that one orbit is completed by Hubble on 90 min. You use the following formula to calculate the speed:

v=\frac{d}{t}=\frac{34,594.59km}{90min}=384.38\frac{km}{min}\approx384\frac{km}{min}

hence, the speed of the Hubble is approximately 384km/min

Two protons, starting several meters apart, are aimed directly at each other with speeds of 2.00 * 105 m>s, measured relative
victus00 [196]

Explanation:

Since, the two protons are at the initial state of point a and point b. Hence, total mechanical energy at point a and point b is as follows.

           U_{a} + K_{a} = U_{b} + K_{b}

or,           K_{a} = U_{b}  

where,   K_{a} = kinetic energy of two protons

So,      2(\frac{1}{2}mV^{2}_{a}) = \frac{1}{4 \pi \epsilon_{o}} \frac{|e|^{2}}{r_{b}}

       r_{b} = \frac{1}{4 \pi \epsilon_{o}} \frac{e^{2}}{mV^{2}_{a}}

Putting the given values into the above formula we will calculate the value of r_{b} as follows.

      r_{b} = \frac{1}{4 \pi \epsilon_{o}} \frac{e^{2}}{mV^{2}_{a}}

                = (9.0 \times 10^{9} Nm^{2}/C^{2} \frac{(1.602 \times 10^{-19}^{2} C}{1.67 \times 10^{-27} kg \times 2 \times 10^{5}}

                = 3.45 \times 10^{-12} m

Now, we will calculate the maximum electric field as follows.

      F = \frac{1}{4 \pi \epsilon_{o}} \frac{|e|^{2}}{r^{2}_{b}}

         = 9.0 \times 10^{9} Nm^{2}/C^{2} \frac{(1.602 \times 10^{-19}C)^{2}}{3.45 \times 10^{-12}}

         = 0.194 \times 10^{-4} N

Therefore, we can conclude that the maximum electric force that these protons will exert on each other is 0.194 \times 10^{-4} N.
