Deciliter = 1/10 of a liter
Milliliter = 1/1000 of a liter
So, there are 100 milliliters in one deciliter
Answer:
R = 73.25 m
Explanation:
We have,
Initial speed of the ball is 27 m/s
It is projected at an angle of 40 degrees
The maximum range of the ball is given by :
![R=\dfrac{u^2\sin2\theta}{g}](https://tex.z-dn.net/?f=R%3D%5Cdfrac%7Bu%5E2%5Csin2%5Ctheta%7D%7Bg%7D)
Plugging all the values we get :
![R=\dfrac{(27)^2\sin2(40)}{9.8}\\R=73.25\ m](https://tex.z-dn.net/?f=R%3D%5Cdfrac%7B%2827%29%5E2%5Csin2%2840%29%7D%7B9.8%7D%5C%5CR%3D73.25%5C%20m)
So, the maximum range of the ball is 73.25 m
Answer:
yes
Explanation:
the brain perform two separate tasks at the same time
<span>THIS IS A GAS PHASE REACTION AND WE ARE GIVE PARTIAL PRESSURES . I WRITE IN TERMS OF P RATHER THAN CONCENTRATION :
lnPso2cl12=-kt+lnPso2cl1
initial partial pressure Pso2cl12 the rate constant k and the time t
lnPso2cl12=(4.5*10-2*s-1)*65*s+ln (375)
so lnPso2cl12=3.002
we take the base e antilog:
lnPso2cl12=e3.002
Pso2cl12=20 torr
we use the integrated first order rate
lnPso2cl12=3.002=k*t+ lnPso2cl12=3.002
we use the same rate constant and initial pressure
k=4.5*10-2*s-1
Pso2cl12=375
Pso2cl12=1* so2cl12
Pso2cl12=37.5 torr
subtract in Pso2cl12 grom both side
lnPso2cl12- lnPso2cl12=-kt
ln(x)-ln(y)=ln (x/y)
ln (Pso2cl12/Pso2cl20)=-kt
we get t
-1/k*ln(Pso2cl12/Pso2cl20)=t
t=51 s</span>
