Answer:
Nerve and muscle function and fluid balance
Explanation:
:)
The resistance of the piece of wire is
where
is the resistivity of the copper
is the length of the piece of wire
is the cross sectional area of the wire
By substituting these values, we find the value of R:
Then, by using Ohm's law, we find the potential difference between the two points of the wire:
Answer:
The correct option is;
Biochemist → Archivist → Civil Engineer → Engineering Technician
Explanation:
1) Biochemist require the completion of a science degree or applied science degree, while biochemist usually hold a PhD to perform research independently, while entry level positions in the profession require a masters or bachelors degree
The PhDs usually require about 5 years to complete, after obtaining the masters degree
2) The general educational requirement to become an archivist is a master's degree in the fields of library science, history, public administration, political science, or archival science, which requires the completion of a bachelors degree followed by the completion of the masters degree which is thus 4 to 6 years
3) Civil engineer title is awarded to holders of a bachelors degree in Civil Engineering which gives the strong mathematical and science background required in the profession usually. The Civil Engineering program duration is five years
4) The engineering technician consist of 8.2% with masters degree, 42.0% have bachelors degree, while it is also possible to become an engineering technician with a GED or a high school degree
Therefore, the usual duration of study to become an engineering technician is two years of an associate degree program.
Answer:
A) Energy is dissipated into heat and sound energy due to Friction
B) The energy goes into heat and sound energy due to friction again, otherwise the cart would accelerate due to an unbalanced force. Therefore, we know there's friction, and the friction causes energy loss.
Answer:
d = 142.5 m
Explanation:
This is a vector exercise. Let's calculate how much the boat travels in the 40s
d₀ = 
t
d₀ = 0.75 40
d₀ = 30 m
Let's write the kinematic equations
Boat
x = d₀ + t
x = 0 + 
t
At the meeting point the coordinate is the same for both
d₀ + t = t
t ( - ) = d₀
t = d₀ / ( - )
The two go in the same direction therefore the speeds have the same sign
t = 30 / (0.95-0.775)
t = 150 s
The distance traveled by man is
d = t
d = 0.95 150
d = 142.5 m
