Answer:
120 km/h
Explanation:
This is a case of a parabolic motion. For this kind of motion the horizontal component of the velocity does not change in the complete trajectory. That is:
Then, the velocity of the ball at the moment in which the catcher caught the ball is:
the velocity of the ball is 120 km/h.
I believe they lose and gain they slowly even out use a periodic table for help
Answer:
Moving electrons by cringing the object near another charged object ... This means that there is a different number of protons and electrons ... the attraction or repulsive electrostatic force between positive and negative charges ... the amount of charge on the particle and the distance between the particles ... fixed in position.ation:
Answer:
0.39AU = 58344000 [km] or 58.500.000 [km]
Explanation:
This is a problem that consists simply in converting units:
AU = astronomic unit
![1 [AU] = 1.496*10^{8} [km]\\0.39 [AU] = x\\\\Therefore\\x = \frac{0.39*1.496*10^{8} }{1} \\x = 58344000[km]](https://tex.z-dn.net/?f=1%20%5BAU%5D%20%3D%201.496%2A10%5E%7B8%7D%20%5Bkm%5D%5C%5C0.39%20%5BAU%5D%20%3D%20x%5C%5C%5C%5CTherefore%5C%5Cx%20%3D%20%5Cfrac%7B0.39%2A1.496%2A10%5E%7B8%7D%20%7D%7B1%7D%20%5C%5Cx%20%3D%2058344000%5Bkm%5D)
Using v=u+at, Where v is final velocity(m/s), u is initial velocity(m/s), a is acceleration(m/s^2) and t is time(s).
v = 0 + 3.2*6
v=19.2 m/s.
