the radius of the tires on a particular vehicle 0.62m if the tires are rotating 5 times per second, what is the velocity of the
tankabanditka [31]
Circumference of the tire = (2 pi) x (radius)

                                     =  (2 pi) x (0.62 meter)

                                     =    3.9 meters

If the tire never slips or skids, then the speed of the vehicle is

             speed  =  (distance)  /  (time to cover the distance)

                       =  (5 x 3.9 meters)  /  1 second

                       =     19.48 meters/second   .

                    (about 43.6 miles per hour)  .

We can't say anything about the vehicle's velocity, because we have
no information about the direction in which it's heading.

suppose a scientific team is trying to recreate the energy producing reactions that occur in the sun. what would they need for t
valentina_108 [34]

For energy producing reactions they need Hydrogen atoms, heat, and pressure for the experiments.

<u>Explanation:</u>

The initial step of the Hydrogen combination process: a core of Deuterium (2H) is shaped from two protons with the discharge of an antielectron and a neutrino. In the fundamental Hydrogen combination cycle, four Hydrogen cores (protons) meet up to make a Helium core.

An atomic combination response is characterized as the response wherein at least two lighter cores consolidate together to shape heavier cores with the arrival of high measures of vitality.

Combination can possibly give the sort of baseload vitality expected to give power to our urban communities and our enterprises. Maintainability: Fusion powers are generally accessible and almost limitless.

A bystander observes the musicians heading toward each other. When musician #1 is 100 m away, the intensity is 1.24 x 10-8 W/m^2
777dan777 [17]

Explanation:

Given that,

Distance 1, r = 100 m

Intensity, I_1=1.24\times 10^{-8}\ W/m^2

If distance 2, r' = 25 m

We need to find the intensity and the intensity level at 25 meters. Intensity and a distance r is given by :

I=\dfrac{P}{4\pi r^2}.........(1)

Let I' is the intensity at r'. So,

I'=\dfrac{P}{4\pi r'^2}............(2)

From equation (1) and (2) :

I'=\dfrac{Ir}{r'^2}

I'=\dfrac{1.24\times 10^{-8}\times 100}{25^2}

I'=1.98\times 10^{-9}\ W/m^2

Intensity level is given by :

dB=10\ log(\dfrac{I'}{I_o}), I_o=10^{-12}\ W/m^2

dB=10\ log(\dfrac{1.98\times 10^{-9}}{10^{-12}})

dB = 32.96 dB

Hence, this is the required solution.

In the 1920s what did Edmund hubble notice about the galaxies
zlopas [31]
Hubble noticed that the galaxies were moving away from us, which meant the universe was expanding.

This is why constellations change over time. In some years, the Big Dipper won't actually look like a dipper anymore.
