Answer:

$^{214} _{83} Bi$ → $^{210}_{81}Tl$ + $^4_2He$

Explanation:

$^{214} _{83} Bi$ → $x$ + $^4_2He$

Subtract the $^4_2He$ from the $^{214} _{83} Bi$

214 - 4 = 210

83 -2 = 81

Therefore, $x$ <em> </em>= $^{210}_{81}Tl$

An old streetcar rounds a flat corner of radius 6.80 m, at 18.0 km/h. What angle with the vertical will be made by the loosely h

Answer:

$\alpha =20.564^{o}$

Explanation:

Given data

Radius R=6.80 m

Velocity v=18 km/h =5 m/s

First we need to set up for Force in vertical (y) and horizontal (x)

∑Fy=0=TCosα-W

∑Fx=ma=Fc=TSinα

Solve Vertical force equation for T,substituting mg for W

$TCos\alpha -W=0\\TCos\alpha=W\\TCos\alpha=mg\\T=(mg/Cos\alpha)$

Substitute expression for Fc and T into horizontal force and simplify it we get

$Fc=TSin\alpha\\ where\\Fc=(mv^{2}/R )\\So\\(mv^{2}/R )=(mg/Cos\alpha )Sin\alpha\\(mv^{2}/R )=mg*tan\alpha\\ tan\alpha =\frac{v^{2} }{Rg}\\ \alpha =tan^{-1}(\frac{(5m/s)^{2} }{(6.80m)(9,8m/s^{2} )} )\\ \alpha =20.564^{o}$

What are barriers to physical fitness and activity?

vagabundo [1.1K]

Barriers to physical fitness and activity may be someone's health (they may have a disease that prevents them from exercising). Other than this, there really is no limit to whom can exercise.

Hope this helps!
