When is an orbital body going it’s slowest? When it is closest to the object it orbits or farthest? Kepler’s Second Law states that the line […]

The coyote’s top speed in km/min is ##1.2 km/min##. ##1 mi=1.609 km## ##1 h=60 min## Multiply the speed in mi/h times the conversion factors from the […]

A longitudinal wave is contracting with the direction of motion not across like ocean waves. A wavelength ##lambda## is measured from contraction to contraction. Example: Sound […]

I found that depends on the ratio of the two masses only. I tried considerng ##p## (along ##x##): Before: ##0## After: ##m_1v_1+m_2v_2## and together: ##0=m_1v_1+m_2v_2## so: […]

Stefan Boltzmann constant= ##5.670373 10^-8 kg *s^-3* K^-4##

Kilo means thousand. So 5 kilometers is 5000 meters.

I got: ##19.8m/s and 9.9 m/s## but check my maths! Have a look:

As the temperature is increased the gas becomes more ideal and the same is true if the pressure is decreased/volume increased. As temperature increases or decreases […]
