Hold up, hee-haw, whoa ! Back it up.
-- When Galileo decided to point his toy telescope at things
in the sky, he discovered moons circling the planet Jupiter.
Right now, in 2016, something like 65 moons of Jupiter are
known. Galileo saw four of them. You can see those too, if
you have binoculars and you know how to find Jupiter in the sky.
-- The Moons aren't "on" Jupiter; they follow orbits around it,
at some considerable distance from it.
-- Galileo didn't 'discover' Jupiter. Jupiter is quite visible to
the unaided eye, and has been for several thousand years.
That's a big part of the reason why Galileo decided to give it
a look-see with his telescope.
Answer:
6.67 meters per second
Explanation:
Velocity is defined as the distance covered divided by the time it took to cover that distance. In your case the car traveled 200 meters in 30 seconds therefore its velocity is: ![velocity = \frac{distance}{time} = \frac{200 m}{30 s} = 6.6666666 \frac{m}{s}](https://tex.z-dn.net/?f=velocity%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D%20%3D%20%5Cfrac%7B200%20m%7D%7B30%20s%7D%20%3D%206.6666666%20%5Cfrac%7Bm%7D%7Bs%7D)
This periodic fraction can be rounded to 6.67 m/s
Now, if they ask you what is the answer in meters per minute, you can give an integer value for your answer simply by using the equivalent of 30 seconds to minutes in the velocity formula:
![velocity = \frac{200 meters}{0.5 minutes} = 400 \frac{m}{min}](https://tex.z-dn.net/?f=velocity%20%3D%20%5Cfrac%7B200%20meters%7D%7B0.5%20minutes%7D%20%3D%20400%20%5Cfrac%7Bm%7D%7Bmin%7D)
Answer:
Physical property
Explanation:
Physical characteristic of matter is not associated with the changes in its chemical composition.Some of these properties are color and density that can be observed without altering the physical state of the matter.Other physical properties such as freezing and melting are observed when a change in physical state of matter. When there is not change in the identities of substances contained in the matter then that's a physical change property.
Answer:
How to find the maximum height of a projectile?
if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest. ...
if α = 45°, then the equation may be written as: ...
if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
