Fermentation is an aerobic process which means it uses oxygen. anaerobic is a process with out oxegyn
Answer:
(A) Torque required is 21.205 N-m
(b) Wok done will be equal to 1199.1286 j
Explanation:
We have given moment of inertia 
Wheel deaccelerate from 135 rpm to 0 rpm
135 rpm = 
Time t = 8 sec
So angular speed 
and 
Angular acceleration is given by 
Torque is given by torque 
Work done to accelerate the vehicle is
Answer:
Explanation:
a ) Let T be tension in the horizontal cable .
Taking torque about hinge of weight and tension
45000 x 7 x cos37 = 3.5 sin 37 x T
T = 119431 N
b ) If R be the reaction force on the hinge
R sin 37 = 45000 ( vertical force balancing each other )
R = 74775 N
c ) The direction of R will be along the bridge
d ) Moment of inertia of bridge
I = Ml² / 3 = (45000 / 9.8 ) x 14² / 3
= 300000.
When cable breaks , the weight creates a torque about the hinge will creates angular acceleration
Torque by weight about the hinge
= 45000 x 7 x cos 37
= 251570
angular acceleration = torque / moment of inertia
= 251570 / 300000
= .84 radian / s²
There are 4 questions related to this problem:
1 If the half-life of the drug is 7.3 hours, what fraction of the drug remains in the patient after 24 hours?The amount of the drug is halved every 7.3-hour period, and 24 hours equals 24/7.3 of these halving periods.
So the portion of the drug left over after 24 hours is (1/2) ^ (24/7.3) = 0.10224 2 Write a general expression for the amount of the drug in the patient immediately after taking the nth dose of the drug
One method is to combine the residual amounts from each amount, when the nth dose arises; this will contain adding a finite geometric series
So the total amount of the drug immediately after the nth dose, in mg, is An = 40+ 40(0.10224) + 40(0.10224)^2 + ... + 40(0.10244)^(n-1)
An = 40[1 - (0.010224)^n]/(1 - 0.10224)
3 Write a broad expression for the quantity of the drug in the patient directly before taking the nth dose of the drug
Pn = An – 40
= 40(0.10224) + 40(0.10224)^2 + ... + 40(0.10244)^(n-1)
= 40(0.10224) [1 - (0.10224)^(n-1)]/(1 – 0.10224)
= 4.0895 [1 - (0.10224)^(n-1)]
4 What is the long-term minimum amount of drug in the patient?
= lim n-->infinity of Pn
= lim n-->infinity of 4.0895[1 - (0.10224)^(n-1)]
= 4.0895(1 - 0)
= 4.0895 mg.
Answer:
a .(b+c) = a.b+a.c
Explanation:
As the three vectors are perpendicular to each other, one of them must lie perpendicular to the plane containing the other two vectors…say a lies perpendicular to the plane of b and c.(b + c )gives another vector which lies in same plane of c and b .
