Dec 26, 2016 · The total length of the road is 125 km We can rewrite this problem as: 60% of what is 75 km? "Percent" or "%" means "out of 100" or "per 100", Therefore 60% can be written as 60/100. When dealing with percents the word "of" means "times" or "to multiply". Finally, lets call the number we are looking for "l". Putting this altogether we can write this equation and solve …

Mar 24, 2018 · "Velocity" = "Displacement"/"Time" "75 km = 75000 m" "1.5 hours = 5400 sec" Applying the formula "Velocity" = "75000 m"/"5400 s" = "13.89 m/s"

Jul 17, 2016 · The reciprocal of the Hubble constant H_0, 1/H_0 is an estimate of the age of our universe, after conversion of units for parity. The explanation gives the computational details.. 1/(Hubble constant) is an estimate for the age of our universe. A recent value of the Hubble constant H_0 is 71 km/sec/mega parsec. 1 mega parsec = 10^6 parsec and 1 parsec = …

Mar 4, 2017 · A car traveling 95 km/h is 210 m behind a truck traveling 75 km/h. How long will it take the car to reach the truck? Physics 1D Motion Displacement and Velocity

Aug 20, 2015 · It lies 75-1000 km (46-621 miles) above the Earth. Free electrons in this layer help in the conduction of electricity in this sphere. Mesosphere - The mesosphere starts at 50 km (31 miles) above Earth's surface and goes up to 85 km (53 miles) high. As you get higher up in the mesosphere, the temperature gets colder.

Nov 16, 2017 · A farmer wants to wall off his four-sided plot of flat land. He measures the first three sides, shown as A, B, and C in the figure, where A = 4.99 km, B = 2.46 km, and C = 3.23 km and then correctly calculates the length and orientation of the fourth side D. A: What is the length of the vector D in kilometers?

Apr 11, 2015 · To calculate the de Broglie wavelength for a particle, or for a tennis ball for that matter, just use the equation p = h/(lamda), where p - the momentum of the atom; h - Planck's constant - 6.626 * 10^(-34)"m"^(2)"kg s"^(-1) lamda - wavelength; Momentum can be expressed as p = m* v, where m - the mass of the particle; v - the speed of the particle. So, starting with …

Oct 21, 2016 · The train speed is 70 km/h, - how long does it take the car to pass it - how far will the car have traveled in that time? An automobile traveling 90 km/h overtakes a 1.5-km-long train traveling in the same direction on a track parallel to the road.
