B) The respiratory system would fail, and then the entire organism would suffer.
Answer:
a) 0.0875A
b) 2.06*10^-6m/s
Explanation:
given
Diameter, d = 2.6mm = 0.0026m
Charge, Q = 420C
Time, t = 80mins = 80*60s = 4800s
Concentration of electrons, n = 5*10^28
To find the current, recall that q = it
Therefore, i = Q/t
Current, i = 420/4800
i = 0.0875A
To get the drift velocity, recall that I = n*q*Vd*A
A = πd²/4
A = π*0.0026²/4
A = 5.3*10^-6m²
Then, Vd = I/nqA
Vd = 0.0875/(5*10^28 * 1.6*10^-19 * 5.3*10^-6)
Vd = 0.0875/42400
Vd = 2.06*10^-6m/s
Note, low Vd causes low current.
Therefore, the current is 0.0875A and the Vd is 2.06*10^-6m/s
C is a correct answer. Because at the bottom, a moving pendulum have the fewest potential energy
Answer:
<em>Fission</em> means breaking.
The process of combining two small nuclei is called <em>fusion</em>.
Explanation:
The process of breaking a heavy nuclei to form two or more lighter nuclei is called <em>Fission</em>.
The heavy nuclei ,like Uranium, are bombarded with slow moving electrons, which are known as thermal electrons. On bombarding, the nuclei disintegrates to form two or more smaller nuclei releasing a huge amount of energy in the process. Fusion is a exothermic process.
The process of fusion is used in nuclear reactors.
Example:
The process of combining two lighter nuclei to form a heavier nuclues is called Fusion.
Energy is released or absorbed during the process.
Fusion takes place in the sun.
We ran out of fuel would be the correct answer - gas is too <span>ambiguous and could be understood and gasoline.</span>
