Answer:
a.) -147V
b.) -120V
c.) 51V
Explanation:
a.) Equation for potential difference is the integral of the electrical field from a to b for the voltage V_ba = V(b)-V(a).
b.) The problem becomes easier to solve if you draw out the circuit. Since potential at Q is 0, then Q is at ground. So voltage across V_MQ is the same as potential at V_M.
c.) Same process as part b. Draw out the circuit and you'll see that the potential a point V_N is the same as the voltage across V_NP added with the 2V from the other box.
Honestly, these things take practice to get used to. It's really hard to explain this.
Answer: hello some parts of your question is missing attached below is the missing information
The radiator of a car is a type of heat exchanger. Hot fluid coming from the car engine, called the coolant, flows through aluminum radiator tubes of thickness d that release heat to the outside air by conduction. The average temperature gradient between the coolant and the outside air is about 130 K/mm . The term ΔT/d is called the temperature gradient which is the temperature difference ΔT between coolant inside and the air outside per unit thickness of tube
answer : Total surface area = 3/2 * area of old radiator
Explanation:
we will use this relation
K =
change in T = ΔT
therefore New Area ( A ) = 3/2 * area of old radiator
Given that the thermal conductivity is the same in the new and old radiators
The statement which best characterizes the relationship between a general contractor and a construction manager is that; A construction manager subcontracts a general contractor to perform <em>work</em>.
A construction project manager is saddled with the responsibility of overseeing the planning and delivery of construction projects.
- In essence, they ensure that work is completed on time and within budget. Other functions include organising logistics, delegation of work and tracking of spending.
A general contractor otherwise known as the prime contractor is responsible for the day-to-day oversight of a construction site,<em> employment of labour, management of vendors and trades, and most importantly, the communication of information to all involved parties throughout the course of a building project.</em>
- <em>Ultimately</em><em>,</em><em> </em><em>the </em><em>relationship</em><em> </em><em>between</em><em> </em><em>a </em><em>general contractor and a construction manager is that; A construction manager subcontracts a general contractor to perform work.</em>
