What is the most likely reason that Mendeleev placed tellurium before iodine?

Physics

Ilya [14]3 years ago

Mendeleev watched that tellurium has compound properties like different components in its gathering, and he didn't realize that neutrons cause the more noteworthy nuclear mass. Mendeleev expressed that he anticipated that tellurium would have a lower nuclear mass than iodine.

A child is sliding down a slide at the playgound. is mechanicalenergy conserved
Flauer [41]

No. Mechanical energy is not conserved.  There's quite a bit of friction on the slide.  So some of the potential energy is lost to heat on the way down, and the child arrives at the bottom with hot pants and less kinetic energy than you might expect.

michael kicks a ball at an angle if 36* horizontal. its initial velocity is 46 m/s. Find the maximum height it can reach, total
MAVERICK [17]

(a) At its maximum height, the ball's vertical velocity is 0. Recall that

{v_y}^2-{v_{0y}}^2=2a_y\Delta y

Then at the maximum height \Delta y=y_{\mathrm{max}}, we have

-\left(\left(46\,\dfrac{\mathrm m}{\mathrm s}\right)\sin36^\circ\right)^2=2\left(-9.8\,\dfrac{\mathrm m}{\mathrm s^2}\right)y_{\mathrm{max}}

\implies y_{\mathrm{max}}=37\,\mathrm m

(b) The time the ball spends in the air is twice the time it takes for the ball to reach its maximum height. The ball's vertical velocity is

v_y=v_{0y}+a_yt

and at its maximum height, v_y=0 so that

0=\left(46\,\dfrac{\mathrm m}{\mathrm s}\right)\sin36^\circ+\left(-9.8\,\dfrac{\mathrm m}{\mathrm s}\right)t

\implies t=2.8\,\mathrm s

which would mean the ball spends a total of about 5.6 seconds in the air.

(c) The ball's horizontal position in the air is given by

x=v_{0x}t

so that after 5.6 seconds, it will have traversed a displacement of

x=\left(46\,\dfrac{\mathrm m}{\mathrm s}\right)\cos36^\circ(5.6\,\mathrm s)

\implies x=180\,\mathrm m

Waves A and B have the same speed, but wave A has a shorter wavelength. Which wave has the higher frequency?
Nuetrik [128]
Frequency and wavelength are inversely proportional.
A shorter wavelength implies a higher frequency.
