Answer:

Who Discovered Gadolinium Gadolinium was only discovered in 1880 by a Swiss chemist called Jean Charles Galissard de Marignac.

Explanation:

When analyzing samples of two minerals which contain small amounts of gadolinium, didymium and gadolinite, he discovered spectroscopic lines that were unrecognisable. Every single element has distinctive spectroscopic lines so he knew he had discovered a new element, and called it gadolinium after Finnish chemist Johan Gadolin.

kotykmax [81]

Getting someone to help you push your car out of a snowdrift.  You both get on the same end of it and push in the same direction.  Another beautiful example is a Tug-o-War, where you might have 50 people (!) all exerting force on the rope in the same direction.

E4.Suppose Galileo’s pulse rate was 75 beats per minute. How many beats per second is this? What is the time in seconds between
Umnica [9.8K]

Answer

given,

Galileo's pulse rate = 75 beats per minutes

Beats per second

1 minutes = 60 s

pulse rate = \dfrac{75}{60}

                  = 1.25 beats/s

times in second

t = \dfrac{1}{1.25}

      t = 0.8 s/pulse

distance of the object

initial velocity = 0 m/s

s = ut + \dfrac{1}{2}gt^2

s = \dfrac{1}{2}\times 9.8\times 0.8^2

      s = 3.14 m

distance in feet

  1 m = 3.28 ft

 3.14 m = 3.14 x 3.28 ft

             = 10.3 ft

distance in feet is equal to 10.3 ft.
