What is the potential difference vab between points a and b when the switch s is open?

1 answer:

3 0

Assuming is a closed circuit when the switch is closed, it would be the strength of the battery in the circuit, assuming a and b were points at each end of the circuit. Depending on the specifics of the circuit, this could change, you could add more batteries together or it could reduce based on resistance if there's a viable current path still open while the switch is open.

Using hooke's law find the elastic constant of a spring that stretches 2 cm when 4newton force is applied to it

Kay [80]

Answer:

2N/cm

Step-by-step explanation:

According to the Hooke's Law, the force required to extend or compress a spring is directly proportional distance you can stretch it, which is represented as:

$F=kx$

where, $F$ is the force which is stretching or compressing the spring,

$k$ is the spring constant; and

$x$ is the distance the spring is stretched.

Substituting the given values to find the elastic constant $k$ to get:

$F=kx$

$4=k(2)$

$k=\frac{4}{2}$

$k=2$

Therefore, the elastic constant is 2 Newton/cm.

The angular width of localizers varies between ______ and ______ degrees in order to provide a signal width of approximately 700

natali 33 [55]

Answer: 10 and 35 degrees

Explanation: Localizers width below 10 degree and 35 degree signal arc is unreliable and considered unusable for navigation and as a result, aircrafts may loose alignment
