Answer:
E=1.969 × 10¹¹ Pa
Explanation:
The formula to apply is;
E=F*L/A*ΔL
where
E=Young modulus of elasticity
F=Force in newtons
L=Original length in meters,m
A=area in square meters m²
ΔL= Change in length in meters,m
Given
F= 8000 lb = 8000*4.448 =35584 N
L= 5 in = 0.127 m
A= 0.7 in² =0.0004516 m²
ΔL = 0.002 in = 5.08e-5 m
Applying the formula
E=(35584 * 0.127)/(0.0004516*5.08e-5 )
E=1.969 × 10¹¹ Pa
Answer:
The voltage needed to accelerate the electron beam is 2.46 x 10^16 Volts
Explanation:
The rate of electron flow is given as:
q = 1015 electrons per second
The total current is given by:
Total Current = (Rate of electron flow)(Charge on one electron)
Total Current = I = (1015 electrons/s)(1.6 x 10^-19 C/electron)
I = 1.624 x 10^-16 A
Now, we know that electric power is given as:
Electric Power = Current x Voltage
P = IV
V = P/I
V = 4 W/1.624 X 10^-16 A
<u>V = 2.46 x 10^16 Volts</u>
Answer:
The fraction of isotope 1 is 50.7 % and fraction fraction of isotope 1 is 49.2 %.
Explanation:
Given that
Weight of isotope 1 = 78.918 amu
Weight of isotope 2 = 80.916 amu
Average atomic weight= 79.903 amu
Lets take fraction of isotope 1 is x then fraction of isotope 2 will be 1-x.
The total weight will be summation of these two isotopes
79.903 = 78.918 x + 80.916(1-x)
By solving above equation
80.916 - 79.903 = (80.916-78.918) x
x=0.507
So the fraction of isotope 1 is 50.7 % and fraction fraction of isotope 1 is 49.2 %.
Answer:
Diphtheria.
Explanation:
Diphtheria can be defined as an acute or highly contagious (infectious) disease of the upper respiratory tract and the nose. It is characterized by the inflammation of the mucous membrane, as well as causing hindrances to proper breath and ingestion through the formation of a false membrane in the throat of living organisms.
Diphtheria is a bacterial disease caused by bacillus Corynebacterium diphtheria excreting a potent toxins in the blood that spreads easily. Therefore, if not treated on time, it could lead to a fatal heart attack, nerve damage or paralysis and death in some cases. Some of the symptoms of diphtheria are fever, sore throat and breathing disorder.
Hence, diphtheria is a disease which affects the throat of living organisms such as humans.
Additionally, diphtheria can be prevented through the use of vaccines or immunization.
