Answer:
The average thickness of the blubber is<u> 0.077 m</u>
Explanation:
Here, we want to calculate the average thickness of the Walrus blubber.
We employ a mathematical formula to calculate this;
The rate of heat transfer(H) through the Walrus blubber = dQ/dT = KA(T2-T1)/L
Where dQ is the change in amount of heat transferred
dT is the temperature gradient(change in temperature) i.e T2-T1
dQ/dT = 220 W
K is the conductivity of fatty tissue without blood = 0.20 (J/s · m · °C)
A is the surface area which is 2.23 m^2
T2 = 37.0 °C
T1 = -1.0 °C
L is ?
We can rewrite the equation in terms of L as follows;
L × dQ/dT = KA(T2-T1)
L = KA(T2-T1) ÷ dQ/dT
Imputing the values listed above;
L = (0.2 * 2.23)(37-(-1))/220
L = (0.2 * 2.23 * 38)/220 = 16.948/220 = 0.077 m
Neither of the technicians are correct.
<h3>Who is a technician?</h3>
A technician simply means an individual who looks after the technical equipments in a company.
In this case, the teeth of the synchronizer are not rounded, the synchronizer can be reused. This shows that he is incorrect likewise technician B.

Answer:
No I don't think NASA is a waste of time. I don't think its a waste of time because NASA is exploring what is beyond Earth and its important to know about Space.
Explanation:
Answer:
Rf=470 ohms R1=10ohms, Schmatic is attached
Explanation:
For non-inverting amplifiers
Gain= 1+(Rf/R1)
480=1+(Rf/R1)
470=Rf/R1
if Rf=470Ω and R1=10Ω
then,
47=47
Answer:
Total kinetic energy= 400 puondal foot
Kinetic energy per unit mass= 8 (poundaul foot/lb)
Explanation:
To determine the total kinetic energy of the block we use the equation:
Kinetic energy = (1/2) × m × (v^{2}) = (1/2) × (50lb) × (4 foot/s)^{2}) =
= 400 poundal foot
To establish the kinetic energy per unit of mass we must simply divide the value of the total kinetic energy obtained previously by the mass of the block obtaining:
Kinetic energy per unit mass= (400 poundal foot) / (50lb) =
= 8 (poundaul foot/lb)
