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:
7500 m/s
Explanation:
We can use the equation velocity of a wave equals wavelength times frequency. Therefore, v = wavelength*f = (25 m)(300 Hz) = m/s7,500
The answer is
D. in a straightforward, objective manner
Answer:
Surface area of the dog is changes from A to 3A
Explanation:
It is given that surface area of dog is increased by factor 3 in a period of 4 year
We have to find the change in dog's relative surface area in the given time period
Let initially the surface area is A
As the surface area is increased by a factor of 3
So surface area after 4 year = 3×A = 3A
So surface area of the dog is changes from A to 3A
