The answer is unbalanced because the numbers 100n and 300n don’t equal each other. If the answer was balanced the numbers would have to equal each other. Also, the answer net force would only be the answer if we were adding the numbers. I hope this helped you! :)
Answer:
110.4 v
Explanation:
Find the equivalent resistance of the two parallel circuits
R1 and R2 in parallel = R1 * R2 / (R1+ R2) = <u>1 ohm </u>
similarly R4 and R5 = <u>4.77 ohms</u>
Now you can add the three resistances into one (R3=10)
1 ohm + 10 ohm + 4.77 ohm = 15.77 ohms
Now
V = IR
V = 7 amps * 15.77 ohm = 110.4 v
Answer:
Explanation:
The mass balance is an application of conservation of mass, to the analysis of physical system. This is given in an equation form as
Input = Output + Accumulation
The conservation law that is used in this analysis of the system actually depends on the context of the problem. Nevertheless, they all revolve around conservation of mass. By conservation of mass, I mean that the fact that matter cannot disappear or be created spontaneously.
Answer:
Charges,
Explanation:
Given that,
Radius of the balls is 2 mm
The force of repulsion acting on the balls, F = 2.75 N
The separation between the spheres, d = 5.33 cm = 0.0533 m
The force of repulsion between charges is given by :






So, the charge on the spheres is
. Hence, this is the required solution.
For the given all options we can find the respective quantity
whenever we have to relate slope of a graph then it is always derivative of quantity on Y axis with respect to X axis
while if we need to find the area of the graph then it is integral of quantity on Y axis with respect to x axis
A. The area under that object's velocity-time graph
this shows area of velocity time graph =
= displacement
so its not correct
B. The slope of that object's position-time graph
This shows slope of position time graph =
= velocity
so this is correct for velocity
C. The slope of that object's velocity-time graph
This shows slope of velocity time graph =
= acceleration
D. The area under that object's position-time graph
this shows the area of position time graph = 
this is no physical quantity
So option B is correct
