Answer:
The force required will be "300 N".
Explanation:
The given values are:
Mass of object,
m = 300 kg
Acceleration,
a = 1 m/s
Now,
The force will be:
⇒
On substituting the values, we get
⇒
⇒
speed of point A is given as
here r = distance from the axis
so here we have
now the distance of point A and B is 0.71 m
while the distance of axis from point A is 0.91 m
so distance of axis from point B will be given as
now for the speed of point b is given as
so end point B will move with speed 37.26 m/s
Answer:
a)54L/min
b)0.845
Explanation:
a) A x V=
where suffix 1,2,3 refers to the three pipes.
=27L/min+16L/min+11 L/min
=54L/min
b) A x V=54L/min => x v
d= 2 cm
x v = 54
v= x
-> x =27L/min => x
= 1.3cm
x = 27
= x
Next is to find the ratio of speed i.e
x / x =>
= 0.845
X -> Y + 2Z
So there are 2 different particles. 1 mol of X produces
1 mol of Y and 2 moles of Z.
Kps = [Y] [Z]^2
We will call “s” (solubility) the molarity of X
So the molarity of Y+ is also “s” (same number)
And the molarity of Z is “2s” (twice as much)
Kps = s*(2s)^2 = s*4s^2=4s^3
If s is multiplied by 2:
Kps = 4*(2s)^3=4*2^3*s^3=4*8*s^3
So Kps is multiplied by 8.
100 years are in 1 century
so if its moving 1km per year that means it would take 10,000 years and to make that into centuries you would divide 10,000 by 100
it would take 100 centuries
