Why does a Parallel Circuit still continue to function after a switch turns off one bulb but continues to pass through the secon

sertanlavr [38]

Explanation:

In short, when we switch off a branch, the remaining branch still forms a complete circuit with the battery, so electricity still pass through the remaining branch.

Technically speaking, the voltage in each branch is the same, and the resistance of the light bulb remains unchanged (neglect effect of temp.) by V=IR, the current should remain unchanged after switching off the other branch.

The acceleration of the boat is $2 m/s^2$ (eastward)

Explanation:

We can solve this problem by using Newton's second law, which states that:

F = ma (1)

where

F is the net force on a body

m is its mass

a is its acceleration

First of all, we have to find the net force acting on the boat. We have:

- The force of the motor, 100 N eastward

- The force of the air resistance, 60 N westward

So the net force is:

F = 100 N - 60 N = 40 N (eastward)

Now we can apply eq.(1), using:

F = 40 N

m = 20 kg (mass of the boat)

and solving for a, we find the acceleration:

$a=\frac{F}{m}=\frac{40}{20}=2.0 m/s^2$

And the direction is the same as the net force (eastward).

A jet plane travels at 40.8 km at an average speed of 340 m/s calculate how long this journey took- giveyour answer to the neare

Tju [1.3M]

Answer:

$2\ \text{minutes}$

Explanation:

d = Distance traveled = 40.8 km

s = Speed of jet = 340 m/s

Time is given by

$t=\dfrac{d}{s}$

$\Rightarrow t=\dfrac{40.8\times 10^3}{340}$

$\Rightarrow t=120\ \text{s}$

$\Rightarrow t=\dfrac{120}{60}=2\ \text{minutes}$

The time taken to complete the journey is $2\ \text{minutes}$ .
