Answer:
The inverse(opposite) relationship between absolute pressure and the volume of a gas. This is known as Boyle's law.
Explanation:
The temperature must be kept the same in a closed system.
Answer:
a) 264.74 N
b) 91.15 N
c) 20.12°
Explanation:
Given:
Angle between the rope and the vertical, θ = 19°
Tension in the rope, T = 280 N
For the system to be in equilibrium,
The net force in vertical as well as in horizontal direction, should be zero
Therefore,
a) For Vertical direction
Weight of the child = vertical component of the tension
W = T cosθ ..............(1)
or
W = 280 cos19° = 264.74 N ............(a)
b) For horizontal
force on the child, F = T sinθ .............(2)
or
F = 280 sin19° = 91.15 N
c) Now, on dividing (1) and (2), we have
W/F = Tcosθ/Tsinθ
or
tanθ = F/W
now, for F = 97 N
tanθ = 97/264.74 = 0.3663 (W from (a))
or
θ = tan⁻¹(0.3663)
or
θ = 20.12°
Answer:
t= 27.38 mins [this the time taken by the enzyme to hydrolyse 80% of the fat present]
Explanation:given values
Half life of lipase t_1/2 = 8 min x 60s/min = 480 s
Rate constant for first order reaction
k_d = 0.6932/480 = 1.44 x 10^-3 s-1
Initial fat concentration S_0 = 45 mol/m3 = 45 mmol/L
rate of hydrolysis Vm0 = 0.07 mmol/L/s
Conversion X = 0.80
Final concentration S = S_0(1-X) = 45 (1-0.80) = 9 mol/m3
K_m = 5mmol/L
time take is given by
![t= -\frac{1}{K_d}ln[1-\frac{K_d}{V_m_0}(k_mln\frac{s_0}{s}+(s_0-s))]](https://tex.z-dn.net/?f=t%3D%20-%5Cfrac%7B1%7D%7BK_d%7Dln%5B1-%5Cfrac%7BK_d%7D%7BV_m_0%7D%28k_mln%5Cfrac%7Bs_0%7D%7Bs%7D%2B%28s_0-s%29%29%5D)
all values are given and putting these value we get
t=1642.83 secs
which is equal to
t= 27.38 mins [this the time taken by the enzyme to hydrolyse 80% of the fat present]
